Sea Surface Temperatures

With global ocean surface temperatures shot way off the charts by mid-March, beyond forty years satellites have monitored sea surface temperatures, we’ve been struggling valiantly to map the changes in sea-surface temperatures, both globally and locally, in satisfactory and meaningful ways. The disruption poised to cascade across the planet in what might be the summer able to make climate change a less contentious issue of politics or partisan polarization. Maps of the remote sensing of surface temperature–sea surface temperature in specific–are shocking as they broker even deeper forms of estrangement, rendering the global temperatures against a baseline of the postwar period. The accumulated data from the first era of remote earth observation by satellite has generated a terrifying picture about which we lack a storyline, or a way to narrate our own relation. The problems of a metageography of impending global collapse that lacks any narrative resolution, more properly, and compels us to attend more closely to the conventions and imagery of how we map sea surfaces to interrogate more closely what we are actually seeing in such maps.

The totality of global warming are nowhere more evident than in the charts of sea-surface anomalies of temperatures, which pool red and orange on the planisphere in unearthly ways, but the correlation of remotely observed temperatures that deviate with standards of a century ago that showed foxing or burning over a decade ago, as the “hotspots” of intense rising temperatures near Greelnaldn, in Hudson’s bay, or off the coast of Maine and Siberia in July 2009 or even more strongly in September, 2011–but demand us to investigate the changing relation of land and sea.

–that have reached such record levels to lead Earth Observatory scientists to describe long-term effects of global warming by diagnosing that the global ocean “has a fever,” with disparities from past averages above three degrees C, not a lexicon of hyperbole, but suggest the inevitability of what early modern physicians would call fast approaching critical days–the discrimination of the moment when the patient will become “critically ill” or persevere, but that challenge us to classify the nature of such critical onset, as the ancient physician Galen felt fevers turn to more severe or worse forms at measurable moments, registering the temporal progression of fevers in his case histories that form the basis for modern clinical records to classify the effects of the fever in its  ‘quotidian’, ‘tertian’ or ‘quartan’ stage. But we sadly seem to lack the same sophistication for record-keeping of global warming, in the age of the Anthropocene. If Galen distinguished fevers by the responses they required from physicians between those that were acute (‘fast’, oxys, or celer) and chronic (‘slow’, chronios, tardus), the action of this oceanic fever requires is particularly acute.

Although Galen suggested that the “best physician” would take care to distinguish and discriminate the causes understanding the imbalances of vital humors that he argued caused illness, the causes that underlie such entirely anthropogenic rises in ocean heat have been increasingly debated and even suppressed, even if there is more than adequate indications that the consumption of energy and burning of extractive fuels have creat4ed and exacerbated temperature anomalies–and little interruption has occurred in the increased extraction of oil and gas under the optimistic slogan of “energy independence”–not actually providing or producing sufficient energy for a nation but exporting more fuels than one imports.

The startling results of remote earth and sea observation stands as an odd counterpart to the iconic “blue marble” that became such a slogan of aspirations to global environmentalism almost a full half century ago. Yet the layers of these mapping tools seem, as the rage for composite forms of IKEA furniture, that arrives in assemblage components, to suggest a readymade far from Marcel Duchamp, as if to respond to the magnification of an imagined “migration crisis” by which the nation is challenged. If that crisis may be in fact false, or imaginary, even if migration rates have changed, and most migrants have arrived in the United States for work. The assemblage of the Border Wall is an elision of the identities and the experiences of migrants themselves, or the routes they travel or their work and trades.

IKEA Börder Wåll (2017)

The layers of our environmental maps of ocean temperature anomalies carry ideological presuppositions leaving us purblind to the massive scale of ecological changes in the global ocean, or ability to steer the results of global warming and planetary change by better grasping its effects, rather than creating indelible images of fear. As the practicalities of building a “Border Wall” with the cheapness Candidate Trump had promised, the proposal to create a readymade Börder Wåll that was a far more affordable option at less than $10 million–exactly $9,999,999,999.99 with a five-year guarantee–used the iconic instructions of the Swedish furniture company to imagine a version able to be assembled by screws and Allen wrenches whose pressboard standing a full ten meters tall. If the more affordable assemblage of the border wall was a potent figure for the political emergence of a salesman with little to offer the nation save the image of security, the layers of the remotely sensed map offer a similarly terrifying othering of the global surface, as if the known world were suddenly at variance from the world that we knew, if not destabilizing the very blueness of the seas.

In the famous “Blue Marble” images taken by those aboard the final Apollo 17 to the moon in 1971, we recognize the continents bathed in a sea of bright blue–continents we recognize from the map, but now see, for the first time, a powerful map, lit by the sun before our eyes. The blue nature of the earth is its most overwhelming aspect, however, unlike a map, as if we can see the sea below sparse cloud cover against the Arabian Peninsula, the Indian Ocean visible from the polar ice cap, with the earth’s other continents for the first time ever: we recognize and identify Africa, Madagascar off its coast, and clouds swirling over the ocean, no nations in evidence. It is othered, but made more recognizable, defined more than by nations by the brilliantly illuminated azure of oceanic blue that seems for all practical purposes to dominate the world’s surface beneath clouds.

The icon of “Apollo’s Eye” soon the most reproduced in world history–an image of technological progress, but also a snapshot from space, taken off-hand at 20,000 miles per hour, a disappearing or receding planet, lit up by the sun, even thought the 70 mm camera on board was not intended for non-scientific ends, and the aweing nature of the film snaphsot was only recognized as it was develped by a film technician as a portrait of the planet. Although its authorship of who reached for one of the several Hasselblad’s not stowed away for more properly “scientific” purposes on the Moon in order to taken one of the great images of space tourism: one of the first remotely “sensed” images of the earth tilting toward the sun’s rays illuminates its blue oceans that are recognizable under swirls of cloud-cover, revealing recognizable continents–Africa; South Asia; Antarctica–from a perspective never before experienced. MODIS satellite reveal show the current oceans no longer as blue, but greenwith phytoplankton as oceans warm the acceleration anthropogenic carbons in the ocean, incubated by human-caused climate change or “planetary warming.” The Blue Marble now definitively receded so that it seems not a Hasselblad image but might be a photoshopped, the seas no longer offer an image of the Blue Marble. And nowhere is the alteration of sea-surfaces evident than in their temperatures, a gradient relatively new to GIS, but all too compelling if also problematic to render in convincing ways. Can we better render the layers of the warming ocean in ways that allow us to better come to terms with the effects of planetary warming?

Blue Marble Photograph by member of Apollo 17 Crew Commanded by Eugene A. Cernan

The Blue Marble image was widely reproduced in global newspapers. But it was only recognized as of interest soon after it was developed by a technician. What NASA called “AS17-148-2272” would be quickly adopted as the “Earth Day” flag. But if it was never definitively credited, and was only in a sense “discovered” by the technician who developed it, its appeal grew as it was consumed by an audience eager to imagine what the members of the space flight teams saw, and as they existed the Earth’s atmosphere. Its immediately recognizable emotive and inspirational power as an image of the earth’s totality as never seen grew, in part, because it was snapped as the winter solstice approached; the full illumination of planet Earth’s vibrant blue oceanic surface appealed as a moral centering, as it became a basis for the Earth Day Flag. Its recognizable nature was not only the crispness of its geographic outlining of continents as they lay and appeared on a terrestrial map,, but, unsurprisingly perhaps, as they echoed and modernized the very claims of divinity that early American environmentalist Henry David Thoreau found as he left Concord ‘s society and his daily job to contemplate the blue waters of Walden Pond he had praised as “cerulean” a hundred and twenty five years earlier, in a wor that was widely read by modern environmentalists in the 1950s and 1960s. The deep blue ocean surfaces from the polar cap of Antarctica to the Mediterranean, around the coast of the entire African continent and stretching to the Persian Gulf, was a counter-map to national maps of borders familiar from school maps, but asking we alter perceptions of the “blue marble” delicately suspended without strings as an image of strength and stability, without any, or at least apparently without any, technological mediation.

But the image of the blueness of those oceans is now undeniably an image that has receded in space, not an eternal image of timelessness, and transcendence, but a definitively receding past, as satellite observations of unprecedented oceanographic detail and range that allowed high-quality ocean color data by the MODIS-Aqua satellite systems announce an inevitably greening of the surfaces of the global ocean. The blue marble icon i, confined to the past, and an artifact of the past, after the anthropogenic alterations of phosphorus and carbons in the global ocean has, in an era of anthropogenic global warming, so boosted phytoplankton populations to recolor the ocean. The new surface ecosystem indicate new variety of microscopic organisms photosynthesizing in the global ocean, and carbon-enriched phytoplankton populations whose abundance in global oceans have “turned the seas green” and “othered” the ocean that was once such a pristine blue.

The iconic call to environmental consciousness map of the blue-drenched seas taken 28,000 miles from Earth at a point where the manned spacecraft crossed the point an Earth fully illuminated by the sun is definitively of the past. Eugene A. Cernan, the commander of the last manned lunar mission who claimed to have taken the photograph claimed to capture the crew’s collective astonishment at the spaceship’s transit before the sun. But he has returned multiple times to the sense of deep surprise by which undoubtedly melancholy window-gazing brought a sudden defamiliarization of earth and disorientation of the observer as much as a feeling of transcendence. It was removed from technology, but made him the most privileged observer of earth with a clarity and simplicity that had in fact been never experienced in history. The placement of himself was as strongly resonant as the fleeting nature of the perspecive, and “Do you know where you are at this point in time and space, and in reality and in existence, when you can look out the window and you’re looking at the most beautiful star in the heavens — the most beautiful because it’s the one we understand and we know, it’s home, it’s people, family, loved, life — and besides that it is beautiful?” The stunning image comprehending oceans and continents with “no strings holding it up,” “in a blackness that is almost beyond conception” in a soothing defamiliarization of awe.

The “blue marble” immediately hat was reproduced globally in print newspapers was an icon of globalism and an image of transcendence before it was an icon of environmentalist Earth Day that would spur a new consciousness of those blue waters’ preciousness and purity by showing them as if they were indeed Walden Pond. The photograph registered an oceanic expanse that appears timeless, and so intensely blue, a pocket of living life that might be modern version of Henry David Thoreau’s praise of the transcendent vitality of Walden Pond’s “cerulean” blues that reflected the sky so intensely as a mirror. (Let’s dwell a bit on this comparison: if Thoreau described the pond as “the landscape’s most beautiful and expressive feature” as “earth’s eye,” “looking into which one the beholder measures his one nature,” and his most prized companion during in “this mode of life” away from Concord, as he grew “suddenly sensible” of a sufficient space nature afforded, we are filled with dread at maps of rising surface temperatures that seem to bode an end to seasonality.) The awe the Apollo 17 Commander Eugene Cernan claimed to be compelled to snap the first image of the earth’s surface, entirely illuminated by the sun’s rays from Apollo 17, the south pole tilted sunward before the winter solstice and oceans illuminated as a seat of life seem a modern updating of Henry David Thoreau’s sensation of being in a privileged site of contact with the divine at Walden Pond. (Cernan’s claim was contested, but he felt the image akin to a re-centering of self.)

The Apollonian view that was communicated globally became an icon of technological progress and of re-familiarization of the earth. This was so much so was this the cast that the image that was reproduced globally with an unprecedented rapidity–a signe of the new globalization of the news–became adopted as an icon of the ecological movement of the first Earth Day, first observed two years previous in 1970, as if to acknowledge how the photograph taken by Cernan or another of his crew effected a changed relation to global space. In sharp contrast, the planispheric image of the increases in global temperatures is a deep dread, provoking an absence of orientation or storyline: dread is the only word for viewers’ disorientation before maps of rising surface temperatures that reveal the disparity of recent global temperatures from the recent past. Is it any coincidence that the seaborne Sargassum proliferated in the mid-Atlantic in record-setting ambient ocean water?

They bode an end not only to seasonality, but the vitality of the global oceans–if not the vitality of the habited world itself. Nowhere is this more apparent than the slick of petroleum that have appeared at the great site of marine diversity and vitality–the Gulf of Mexico–that has become a hub of the offloading of global oil supplies to the Americas for processing, seen as a “chokehold” for daily maritime oil transport of the 56.5 million barrels that traveled on maritime routes–about 63% of world’s total oil production. Indeed, the critical maritime routes for the global transit of oil were long referred to as “chokepoints”–

The registering of land temperatures monitored from satellites at a closer distance has created far more terrifying images of defamiliarization this summer and in recent years. The temperatures anomalies is hard to recognize as anything like a map that we might easily recognize, and indeed push the boundaries between cartography and art. If all art may be about estrangement–ostranenie for Russian formalist literary critic Victor Shklovsky and his circle–or “defamiliarization” of the known, the estrangement of global warming temperatures area shocker and an artistic narrative we do not know what to make of save as a learning model for the entrance into the new era of the Anthropocene.

If the politics of estrangement was for Shklovsky rooted in a new sense of life become art, and a revolutionary estrangement of self, global warming seems the utmost in estrangement, although what living through global warming honestly remains hard to come to terms or conceive. It is, for one, outside of our familiar narratives, save the apocalyptic, and we may tend to the apocalyptic as a result. But, this post will suggest, the danger is in a sense deeper than a failure of narrative alone and in ways that we may take a clue from the Russian formalists themselves to understand: for the formal presuppositions of visualizing and of mapping sea temperatures as continuous with land, and as able to be mapped in the same terms as the anomalies of land temperatures, is an ideologic construct and choice, independent of the content of the global maps of raising temperature: for we flatten the sea temperatures at our own risk. Flattening the ocean expanse as if it were akin to land temperatures ignores the extent to which greater heat that drive increasing global temperatures have been storied within the ocean, and the risks of rapidly cascading nature of changes in ocean temperatures that anthropogenic change has produced.

Indeed, the critical ways that mapping sea surface temperatures and mapping ocean resuources as if they were sites for extraction, akin to land-extraction, has led to an increased dependence and sanctioning of offshore waters for extractive drilling, as nations from Canada to Russia to the United States to Argentina to Mexico aim to expropriate underground reserves of oil to boost their national economies and trade, auctioning off lots to the highest bidde, or subsidizing offshore drilling of gas and oil. These huge anthropogenic changee masked or concealed by relying on the relatively surperficial maps of remote satellite sensing of sea surface temperatures alone.

By the middle of June, the GIS anomalies of global temperatures from a baseline of my pre-college years revealed how much personal history had intersected with a radical change in global climate. One’s life memories somewhat incredibly and suddenly in synch with global epochs, reminding me of how very unlike global temperatures for most were compared to the normal in my own memory as well as that of the planet–a daunting prospect and possibility indeed to get one’s mind around. (It’s hard, however, not to wince at the echo of the fractured partisan topography in this map of global temperature change, even if the confine of blue to the arctic regions and western and northeastern United States ; the carmine warming temperatures looming over Canada is quite hard to dissociate from the dry forests that ignited in fires across so much of the nation this summer.)

The view from a generation–if not a life perspective–showed a modeled planisphere hard to get one’s mind around, scorched by temperature anomalies, from the ocean off of South America, the arc under the Aleutian Islands, the hot-spot off of west Africa and burn holes of Europe and Siberia. The warming of the global atmosphere was long seen as “one of the most pressing problems of the twenty-first century,” the global maps of heightened atmospheric warming due to elevated carbon levels now a full 50% above preindustrial levels–and larger than ever seen on earth since three to five million years ago–according to paleoclimatic data–make it hard to place the climate changes amplified by greater methane, nitrous oxide, and fluorinated gases. It is a register of the all too human art to burn carbon, if not just a deeply depressing image leaves one drained of any agency; it is hard to stand before it with anything like the exultant transcendence of fifty years previous.

As carbon levels continue to crest above 420 ppm, we look back at the high levels of CO2 fifty million years ago, average temperatures reached about 10°C warmer than today and the planet ice-free, with sea-levels lapping shores two hundred feet higher above current sea-level. One can segment it many ways, but the huge escalation of temperatures of the oceans–which have stored a vast amount the growing heat we experience on earth, or a whopping 93%–moves unlike how heat is experienced in land, but reflects the most densely populated coasts–and densest sites of anthropogenic waste–

–in the global ocean.

The warming of seas were long recognized just several years ago–in relation to a dataset from the twentieth century and first two decades of the twenty-first–in ways that call attention to just how much atmospheric heat the global ocean has absorbed into its own waters in the past century–and how much more it has additionally absorbed, perhaps putting it over the top as a site able to sustain life, in recent years. If death was the “master fear” that philosophy was able to conquer for stoic philosophers from Seneca to later Romans, able to be overcome to conquer fear itself, the increasingly inhospitable global oceans suggest little to meditate upon we have an ability to process save their own evanescence as habitat for life: the images are perhaps not records of a life lived, but are literally the collective residues of “lives lived” in the twentieth and twenty-first centuries. There is no known script of how to live that they offer for virtue or nobility.

We are increasingly pessimistic about our world view, and the maps of global warming fit with an increasingly pessimistic world view that has been seen as a problem of global purpose, at least from the US-led invasion of Iraq in 2003 without debate that after eight years of conflict saw “shock and awe” lead to wide questioning if it was worth fighting. If the 3.4 million aircraft sorties that dropped the equivalent of 640 Hiroshima bombs in Cambodia and Laos had cast a shadow over America’s global purpose for one generations, the burning of 700 out of control oil field fires lit by retreating Iraqi forces as they withdrew from Kuwait under fire: as U.S. and allied troops arrived to defend the fields in a war of a hundred hours, of bombing sorties of air-launched cruise missiles, Iraqis lit wells as they retreated to blanket the air rendered unbreathable for soldiers without gas masks in improvised smoke screens of toxic with particulate matter. As “allied” intervention destroyed an amazing 3,000 tanks and 1,400 armed personnel carriers in a matter of days, with countless other vehicles, the plumes of 700 gushing wells were lit, creating up to 300 oil lakes in the desert whose pollution of the soil is as deep as four meters today, now hardened to sludge leaving lakes that are toxic today, even as almost two and a half million cubic meters of sand were cleared. Concservationists remained concerned about continued effects on humans and the environment.

The very commodity over which the war was fought became an aggressive act for the military advantage, squandering petroleum resources the west valued in an age of ecological aggression the transformed the Greater Burgan oil fields into an anthropogenic inferno. Wells were commandeered in a scorched earth policy of unprecedented scale, an environmental disaster that cost over a billion to extinguish, individual wells only able to be extinguished at a rate of one or two a day, as forces were anticipating billions to reconstruct the fields the United States led “allied” forces to defend. The anthropogenic effects may be obscured by of the sovereignty of Empire, far beyond the bounds of the nation state, and the bounds of the Kuwaiti oil fields.

If the logic of direct intervention in the 100 hour war depended on the myth of effective global military apparatus ready to wage a “just” war, asserting military control over Iraqi and Kuwaiti oil fields in the logic of war, the lighting of oil rigs and gas rigs by retreating troop and bombs improvised a network of resistance, blanketing the region with smoke that made aerial surveillance impossible and useless, and offered deep health risks to those troops with “boots on the ground.” As wells burned they ignited the very source of one of the sources of shipments of crude to be refined in the Gulf of Mexico, where much global petroleum is offloaded. The arrival of petroleum in the Gulf’s dispersed system of refineries and multinational companies was a basis for the extension of “American interests” to a region in the Gulf seen as so critical to the globally extended economy to justify the “just war” by American-led forces. The global web of oil refineries across the coastal region was a way in which the wealth of the United States was preserved and transportation economy fed. If oil spills had declined in recent years in U.S. marine waters, the offloading of forign oil in a network of refineries established in American waters in a site of deepewater oil and gas production was a basis for the extension of American “sovereignty” that had ignored the anthropogenic effects of oil toxins was released in the war, if far beyond the US coasts.

Oil Toxins Pervasive in Gulf of Mexico

If America was stunned that the United States had coordinated the Iraqi invasion of the oilfields in Kuwait, the new source of most oil refined by American oil companies on shore, the war that was fundamentally about blurred borders, and control over the continued flow of extracted petroleum and gas for commodities, the burning oil fields took back the very grounds of production by lighting the oil rigs as torches in the night.

“Kuwait Oil Spill, 1991” by Christopher Gomez (2016)

The anthropogenic scars of the 1991 war with Iraq created warnings of a nuclear winter never to materialize in 1991, burning of hundreds of thousands of barrels released one and a half billion barrels of crude into the environment including “oil lakes” burning for months created but 2% of global emissions. A further hundreds of thousands of barrels of oil from oil field rigs gushed through most of 1991–a record of anthropogenic harm predating Paul Crutzen’s popularization of the concept of a geological epoch distinguishable by its environmental archeology. While the Anthropocene is dated as most evident from the 1950s, as the acceleration of technologies and explosion of atomic bombs left new residues on mountainsides and the planet, the invasion came at the end of the Cold War, at a time when the mobility of troops across the planet had grown in a converse of globalization. The ability to move troops to “invade” or “free” Kuwaiti oil field by aerial bombardment, that mobilized thirty one nation alliance against “military targets” by B-52 strikes and hellfire missiles to prevent Iraq from occupying the oil reserves on which America depended was called a “just war,” but the intervention led to the combustion of eight hundred oil well rigs, three quarters catching fire and burning, and fifty gushing oil onto the ground, until they were capped in October 1991.

The drive to protect oil and gas led to oil fires burning, releasing about 355,000 tons of crude. Their destruction was a retaliation of the sovereign control of speedy troop movements in an intervention that paradigmatically revealed a new sense of Empire asserting sovereign control over Kuwaiti oil fields in a self-defined “just war.” It became a monument of anthropogenic alteration of the landscape by an environmental disaster of new proportions and scale. If the term “boots on the ground” only gained currency in the Invasion of Kuwait, the term that dates in the military from the hostage crisis in Iran suggests the limits and frustration of global mobility, but conceals how the grounds of the region were altered in decisive ways, responding to how the United States showed its readiness to move anywhere in the world with a massive show of force of unprecedented scale, in a new multi-national effort difficult to map or narrate as a story of “boots on the ground,” or to register in the consequences of how multi-national forces intervened in oil fields in Desert Storm.

Operation Desert Storm/U.S. Aarmy

The burning of wells by retreating Iraqi troops left a residue left across the desert sands. Accumulated soot from petroleum refineries and carbon–“tarcrete”–spread as a residue of the war; the dark plumes continued to spew400 metric tons of particulate matter of 2.5μm daily from oil wells with over a hundred million cubic meters of natural gas; sixty to eight million barrels of oil directly entered the Gulf in a major environmental disaster that affected the entire ecosystem, as at least fifty oil wells gushed to the ground and eight hundred were destroyed with explosives, if the total carbon emissions were 2-3% of the global annual anthropogenic burning of fossil fuels and but 0.1% of global CO2 emissions. The local density of soot in the Arabian peninsula lowered climate temperatures by 10 degrees C, and covered extensive areas in Kuwait, Northern Saudi Arabia and the Gulf. Gushing wells flooded the oil fields with lakes of petroleum of up to ten hectares, polluting the Gulf, nearly fifteen thousand million cubic meters of oil leaching in Burgan alone–a site of major air attacks–and 22.5 thousand million in total, much from the armored tanks an munitions were abandoned by soldiers in the desert.

Air Attacks and Major Clashes where Depleted Uranium Rounds Fired into Kuwaiti Oilfields

If the 1991 invasion was a critical starting point in staging a deep environmental estrangement than the rise of the new form of military intervention Negri and Hardt argued epitomized the global interventions for just wars in the new legal formation of Empire. The aggressive American-led military intervention ostensibly to “maintain peace and order” by ensuring the smooth circulation of petroleum extraction from the oil fields of Kuwait and Iraq that were the true targets of western desire. But was the burning of oil wells on the border of Iraq not an active rejection of the claims of this new formation of Empire to the Kuwaiti oil fields? Before a feared economic disintegration of multinational claims, the military intervention and conquest sought to construct a global order superseding time to replace it with “free markets,” Negri and Hardt argued, beginning from the military interventions that precipitated the Gulf War.

In response, Iraqi troops set rigs on fire by wresting control of the very underground deposits of petroleum defined as the economic resources of the region, using the infrastructure of energy companies to upend the peaceful new neoliberal order so blithely unilaterally proclaimed. The consumption by combustion of the gushing rigs that were an infrastructure of global energy networks were appropriated as the sites of resistance against the western “peace-keeping” forces that arrived from the air. Who is to say it was not staging resistance on the ground, from the ground up? The redirected anthropogenic effects of a massive project of extraction as Iraqi troops unexpectedly released improvised smoke-cover undermined the organization of a planned international military intervention of a “just war” monitored from above by satellites as a massive disproportionate show of force and deployment of troops by obscuring it from satellite monitoring from a new theater of war. If the war depended on an effective image and logic of military control over Iraqi airspace, the seven hundred oil rigs that burned as a monument to the Anthropocene offered an improvised network of resistance, blanketing the region with smoke that made air surveillance impossible, subverting mapping military progress by satellite from the ground and subverting the smooth exercise of power over the space of what was define as a Just war against Iraq.

When Oil Fields Burned (1991), Sebastião Salgado/Amazonas

If the months leading up to the invasion of Iraqi-held Kuwait met the criteria of Christian “just war” doctrine formulated by St. Augustine, and refined by the scholastic theologian Thomas of Aquinas, the claims of legitimacy of an invasion to secure peace in the region was closely tied to apocalyptic outcomes: as retreating Iraqi forces lit the abandoned oil fields, even if the feared “Nuclear Winter” or year without summer did not materialize, the dense plumes of smoke spreading hundreds of kilometers from multiple points in oil fields set a new standard of fear in haunting images of burning oilfields streaming black smoke, as periodic oil fires have since haunted the region. The model of imperial authority was maudlin if not blatantly absurd. Could the pastoralism of Kuwaiti shepherd corralling sheep and goats–most of whom are in fact migrant workers from Uttar Pradesh or other Indian states–be more mismatched than against the apocalyptic billowing black clouds that drove streams of particulate matter across the skies?

Was the fear not an attempt to come to terms with the unprecedented global scale of such then-devastating environmental aftermaths? The oil plumes streaming hundreds of kilometers across the horion have provided a topos to which later wars in Iraq and Afghanistan have returned, an image of the iconic burning of oil once stored underground, in reserves–releasing more than twice as many barrels of oil into the Persian Gulf as the Deepwater Horizon would release in the Gulf of Mexico, and spreading eight times as many across the desert.

The jarring image of the burning blazes of the swells in a region defined by its pastoral economy suggested the deeply dissonant historical circularity of the claims to Empire that were at stake across borders, as troops on the ground were sent to defend multinationals’ interests–if with democratic pieties–the first great neoliberal war defined by alleged defense of Kuwaiti sovereignty by a “line in the sand” was the first war of Empire, for Negri and Hardt, in a boundless, universal space: the plumes spreading to international air space–as well as a hazard for those breathing on the ground:

Plumes from Kuwaiti Oil Wells Burning around Kuwait City in April 7, 1991 from Space Shuttle Atlantis/ NASA’s Earth Observatory

The streams of black particulate matter that was so toxic to the lungs of those with “boots on the ground” defending oil fields in Kuwait were grasped in global terms, less in terms of Empire than another global climactic events–if this time released by man, blaming the Iraqi troops for loosing the fires in response to massively disproportionate air fire launched against them for a famously brief hundred hour war entitled “Operation Desert Storm,” a multinational military seizing of oil fields cast as a “just war” but revealing increased global energy dependence on extracted crude.

The black smoke issuing from burning rigs were feared to englobe the world in a “little ice age” akin to the black ash clouds that were emitted into the global atmosphere at the 1883 volcanic explosion of Krakatoa, or four volcanic eruptions that had earlier led to the expansion of the Arctic Sea circa 1275-1300, leading to the expansion of glacial valleys in Europe from the Alps to Norway, in a similarly global cataclysm of man-made origin, and came to be paradigmatic of the definition of barbarism versus civilization, or the economic status quo, or democracy versus totalitarianism. Burning of oil fields, many not fully exhausted or capped until November, 1991, spewed or released petroleum into the desert and river or Gulf for up to eight months, creating new “oil seas” of toxic character, set a stage for the burning of gushing and roaring in future wars in northern Iraq that have colored the desert landscape with a dark anthropogenic pall of thick, dark smoke, repurposing a geography of oil fields as geopolitical tools of, normalizing the burning of 4.6 million barrels/day by 2016-17 whose blanket of fine carbon dust blocked solar rays to cool local temperatures.

Oil Fires in Iraq

The pessimism of purpose in the world extends to the and infects the warming of our global temperatures, as if to condemn us to a history of carbon extraction of which the Gulf War was the iconic turning point. Temperature rise is easily seen as part of a pessimistic world picture we cannot intervene, as if evidence of inevitable products of life of a carbon-burning age, the rise of temperatures. the age was spurred by the billions made from the postwar extraction of carbon-rich fuels have been the stimulus of an overheating planet, bringing temperatures of oceans and land alike–albeit in importantly different ways–to a tipping point, starting from that harrowing moment of apparent apocalyptic images of burning oil wells in 1991, the spewing of tarcrete seemed to confirm the arrival of an age of the Anthropocene before the word emerged in the critical literature–an age defined by the spread of economies of extraction as the dominant means of moving far beyond sovereign bounds.

The increasing quantities of “accidental” spills that have been occurring in the United States since 2010 alone have led to a blossoming of pipeline leaks, shipping accidents, train derailments and industrial disasters that have revealed the downside of the extractive industries the government overabundantly subsidizes and funds: over half the spills were of crude oil, and a further third petroleum products, and a sixth highly flammable gas. The small number of leaks of ammonia and other highly volatile liquids made from petroleum should not detract from their high levels of their toxicity: the greatest number of accidents of costly crude spills whose clean-up can continue for years range from petroleum products such as diesel or gasoline, to liquefied natural gas or crude, have an unsurprising epicenter around the Gulf of Mexico, per Visual Capitalists Preyash Shah, and can include the very liquified CO2 products under high pressure regularly transported in pipelines, commonly used for carbon capture storage. If almost have of such spills have been mapped in Texas (site of 40% of the almost 5,000 spills that were mapped in the twelve years 2010-2022, the leaking of crude and natural gas plumes across the density of offshore platforms along the Louisiana Coast is downright terrifying.

It is all too problematic that the very same companies benefitting form gas and oil extraction are now at work–from Occidental Petroleum to Exxon Mobil to Chevron to Shell–on the unproven Direct Air Capture technologies, misleadingly billed as a means to achieve emissions reduction goals set in the recent Paris Climate Accords and as the corporate ticket to “carbon neutrality.” This is the new gospel of a soft neoliberalism in which the government would outsource aging infrastructure of energy extraction to capture carbon from the air at the very site of its release by energy corporations. If a “soft neo-liberalism” at the edges of the nation state, the expansion of public-private partnerships that extend offshore into Gulf of Mexico, beyond the edges of the nation, are haunted by the terrifying LandSat images of a landscape of hundreds of oil fields burning out of control.

For in reaction to the 1991 arrival of American-led “boots on the ground” forces in Kuwait, who waged all-night battles on the Euphrates, Iraqi troops repurposed the underground reserves of subterranean oil fields to super-abundant Molotov cocktails thrown into the atmosphere far beyond sovereign bounds. The striking televised footage of the global dispersion of carbon ash, that almost replaced teh expectant footage of a ready and easy victory, anticipated the billowing towers of the foormer World Trade Center, belching black smoke from the combusting contents of the tankers of airlines that later flew into the twin towers. If the towers billowing black smoke in lower Manhattan was an icon of the War on Terror and of the Gulf War, the unstoppable release of those hundreds of oil fields senselessly burning oil, as if to reappropriate the crude bound for western tankers in the Gulf, and energy markets abroad, the staking of oil sovereignty in the Atlantic seems to bring the reserves extracted far, far closer to home. T he unpromising and unproven promise of carbon removal by Direct Air Capture seems to rewrite the wounds of Middle Eastern wars of oil sovereignty closer offshore, mapping a new image of petrosovereignty in an age of Empire. Carbon removal is promoted as a way of justifying petroleum and gas extraction in an era of extreme climate change–and climate activists urged to support carbon removal by Direct Air Capture even as oil companies have treat it as grounds to continue drilling, producing and using fossil fuels.

We are argued to have no other option, but our backs are up against the wall if we hope to stay the rising of ocean temperatures. There may be virtue in recycling, but the density of this color spectrum, tending from red to carmine, only illuminate a massive shift on a scale we have no clear ability to presume a personal relation to–or perhaps even the cognitive ability to grasp fully. We stand before these maps haunted by a deep dread, a fear that is perhaps debilitating more than empowered, but perhaps diminished by what has preceded, and with no sense of rational decision–although we are tempted to arrive at many a quick fix to steer back from the apocalypse of warming oceans. Can the deep reds be anything other than a warning of warming to come, a continuation of the global trends of dramatically increased ocean warming and sea surface heat.

The rasterization of the global ellipsoid suggests a dangerous distance from the mechanics of warming, even if it maps the globe on a jarring color ramp we have not seen before, or are likely to be able to interpret. The very etheriality of these raster maps of temperature anomalies are striking as they cast the ocean on a distinctly red color ramp. As if in synchony with the massive waves of coral bleaching in global oceans–whose impact and scale we cannot yet calculate–we find things of the impending nature of ecosystemic colapse that fills with palpable dread, but is more striking in its absence of any fitting narrative. If the story is tragic, and existential in scope, the cognitively disarming nature of these pixellated maps are as strikningly removed from any material basis, and lacks any clear distance to comprehend as it is bereft of any narrative.

It seems the lack of clear narrative, and the alarm of red, leads to such perhaps well-intentioned but tragically desperate cries for help as Just Stop Oil protestors calling for the immediate end of fossil fuels by using orange florescent spray paint to target the neoclassical Radcliffe Camera icon of Oxford’s Bodleian Library, spraying a fluorescent orange on a structure built 1737-1749 to embody Enlightenment ideals. The Palladian domed building might typify the Enlightenment, targeted as if the root of deep ignorance of the consequences of extraction, but also illustrates an inability to imagine any end-game save cessation of use of extractive fuels across the entire global economy. The rugged demand–Just Stop Oil!–suggests a purblind view of the interests at play–is it only government or any government, or isn’t the problem a little more manifold? can orange spraypaint to deface a heritage structure really make a mark, or is it just a muffled cry for help?

Hugh Warwick/October 10, 2023

Welcome to truly desperate times. The intense orange removed by power0hoses hours after a disgruntled Oxford student and his mate seem to have repurposed the immediacy of Nike’s corporate slogan suggest nothing less than an existential sense of the teetering image of the world’s environment that could not but echo the insisted on recent temperature trends that have lasted the lives of the ecological activists, twenty-one and eighteen year respectively, taking a stand against the markedly uncontrolled increased warming of land areas and wildly shifting extremes of seasonal temperature that had led to the expansive melting of arctic regions. Following the alarming colors of temperatures changes NOAA features on the Climate Dashboard, the spread of rising temperatures by over half a degree Fahrenheit/decade are truly causes for alarm.

Climate Dashboard: Changes in Climate Temperature by Decade , 1993-2022

But the deep orange hues of the slogan of the Just Stop Oil folks earnestly demanding “no new oil, no new gas or coal” are calling for a “deliberate disobedience” that the spray-painting of Radcliffe Hall–a symbol of Oxford–inaugurates across three weeks of action from October 29, akin to a reckoning, designed to appeal to students, promises a greater sense of agency and empowerment in a world where “No-one’s going to save us, we have to come together to do that for ourselves” in time for Halloween, as if to grab the steering wheel on a car that has been driving out of control, and force the hand of civil government by collective actions of “deliberate disobedience”– assuming equivalent existential urgency of the dispossessed: “what will the Government do? Concede to our demand, or crack down and arrest us all?” The Oxford protests, on the heels of the spraying of Bristol’s Queens building with the same bright orange paint, urging all faculty and students to join in the “civil resistance,” led to the Oxford student to claim to be “taking action to resist the destruction of my generation,” noting the scale of the climate crisis of which “Oxford academics are fully aware of,” but despite knowledge of fast-approaching “unsurvivable heat and humidity” that will force “hundreds of millions of people will be forced to move, or die” is tantamount to genocide.

Before “the annihilation of everything we care about,” the Oxford student who defaced a site of study by florescent orange paint seemed to interrupt quiescent study. On the heels of the spraying of a building in Bristol’s Queens building with analogously orange industrial paint, asking all university students and faculty to unite in a “civil resistance” to extractive energy, the Oxford undergraduate felt he was “taking action to resist the destruction of my generation” in existential terms, decrying how “Oxford academics are fully aware of the scale of the climate crisis” but ignore it. As a member of Just Stop Oil, a coalition committed to forcing the government to end “all new licences and consents for the exploration, development and production of fossil fuels in the UK,” he was confined of the need to stop a narrative of planetary warming that has an inevitably tragic end.

Have we failed this generation, and indeed failed the cause of climate change, by maps that assume an impending disaster of warming that offer no possibility of change or berth of safety or remove? This seems a Eurocene, to be sure, as much as an Anthropocene, of unconscionable harm to habitat range, environment, and ecosystems as a massive amount of energy has been insistently raising global temperatures by extra unwanted heat. The recent rasterization of our ocean maps–we map less bathymetry than temperature anomalies in the daily coral reef watch–recast the ocean as haunted by color ramps we have never seen before, pressing us to create stories and gain a grasp on what has been happening with the oceans as they warm in dangerous directions across the north.

The liability of such raster maps may lie in their eery ethereality: a pixellated space distances us from the materiality of climate change. For rasterization problematically offers an eerily immaterial way to view global warming unhelpful in its terrifying immateriality, as if blocks of predestined pigment sprayed across the ellipsoid outlines globe at a distance and from on high mark the bleaching of ocean life. It is terrifyingly inappropriate not only in its lack of narrative–if the story is tragic, and it is existential to boot–but cognitively disarming as it is removed from any precedent, wrapping the surface of a globe as if spray-painted across the flat ellipsoid disk we struggle to map to particular losses, filled with forebodings of increaed global warmth.

But we have hard time focussing on the shores as endangered areas by the disproportionately warming global ocean, overwhelmed by data that we are cognitively challenged to process. The late historian John Gillis warned us often of the danger of such assertive and short-sighted “turning one’s back on the sea”–and Gillis was worried that we had done so as a culture and society to our great detriment–rising ocean heat and sea surface temperatures remind us of the disproportionate amount of heat that has been absorbed in global oceans, and the danger of having remade the ocean as a vital habitat. For the shores have been unjustly ignored, as a space whose ecology we might do well to focus as sites suffering from anthropogenic change. We have a hard time focus on the vulnerability of the shores as ecosystems, indeed, so often do we see surging seas as a threat to human habitation of the shoreline, rather than having a broader sense of the threat to the ocean biome as a threat from largely anthropogenic warming. Yet as they are so vulnerable, and so potentially rich with significance as vital membranes of the planet. they are precisely where we must attend with greater atteniotn, as we try to parseunprecedented risks of overheating.

Even as country-based promises to reduce rates of carbon emissions became the talk of the town after the Paris Accords, with few imagining reductions likely for most of the developed world, before the United States withdrew from the global accord, which had pledged to cut 52.4 billion tonnes of emissions, on a global scale, little probability of the reduction to goals by the highest emitters–China; Western Europe (EU); Brazil; Canada; Japan–we face the global impact of planetary warming with few guideposts, precedents, or narratives to process catastrophic climate change.

We risk casting anomalies of surface temperatures and indeed looming rises in surface temperature as but the latest flattening of the world’s surface, eliding differences of land and sea temperatures that fails to come to terms with the cascading consequences and scale of anthropogenic climate change. For the most striking aspects of the rising surface temperatures on the planet may be the rising warmth of ocean waters. And the registering of global waters suggests, not paradoxically, both the liability of a focus of most mapping on the land–and extension of terrestrial coordinates to the oceanic surface, as if the anthropocentric claims of land maps might be extended, with brash or unwarranted assurance, into the ocean, without appreciation of the degree to which oceans have absorbed the great preponderance of anthropogenic heat: does an anthropocentric map of land effectively elide the extent of anthropogenic influences on global surface temperatures? Offering a private record to observe temperature variations that are remotely sensed, we may be foreclosing our relations to our own surroundings, and indeed of the relation of species beyond the human to the oceans as globally vital habitats.

But in mapping temperature rises as part of a continuation of land temperature anomalies, we may not grasp the full extent of the problem–and only risk entering into a climate apocalypse. So, indeed, runs the presuppositions implicit in the newly vaunted technologies of Direct Air Capture (DAC), the neo-liberal promise of carbon sequestration, by projects promising to capture carbon at the sites where it is produced that is being entrusted–bottled at the source!–that seven of the largest oil and gas companies are promoting as a public-private venture to “remove legacy emissions” even as the oceans warmed. For DAV is billed as the new mission of energy companies to use their existing infrastructure in offshore a reas to make good on the danger of the climate scenarios such maps threateningly propose, treating the recent promise of Direct Air Capture, if unproven, as a awaits public funds to “flow into the [existing energy] sector so it can scale,” with Occidental Petroleum floating promises to remove one million metric tons of CO2 every year by what is billed as a model for what the “best, most sophisticated, most committed companies” in the oil and gas businesses who are rooted in extractive industries should do “to preserve our industry over time.” Occidental Petroleum’s CEO is making a rather desperate argument as the nation’s energy companies have their backs up against the wall if they want to continue to emit more carbon, with carbon being the prime contributor to and accelerator of anthropogenic climate change.

For if its technology is unproven, it ostensibly or plausibly offers carbon-based energy companies an basis to sustain DAC can leverage a write-off able to balance out costs of future carbon emissions by using machines on the drawing boards to “pull carbon from the air” of unproven efficiency, erasing future costs of carbon burning, and overlooking the past costs of carbon emissions energy companies have themselves so conspicuously historically contributed.

Fossil Fuel Emissions Inventory per Capita based on 2000 Census/Kevin Gurney and Vulcan Project, Purdue

The unproven technology uses the very tools of extractive industry to inject and store carbon in the earth’s surface, , creating a tool akin to double-entry bookkeeping to balance the costs of future energy develpment against the removal of carbon that may well in the end return to the earth’s atmosphere without ever needing to reduce emissions. “Direct Air Capture” is a new language of soft neoliberalism, fulfilling needs to acknowledge the untenable scale of costs of carbon emissions, but scaling up their own responsibilities to reduce emissions by promises to sequester carbon in underground reserves, of putting the greenhouse gases back where the oil was extracted years ago, and indeed filling up old empty oil mines with carbon reserves in the Permian basin. Although the largest DAC plant removes only 4,000 tonnes of CO2 from the air per year, the logic of an enormous growth of investing in technologies of Direct Air Capture plants could eventually and only by the middle of the twenty-first century extract a full gigaton of the carbon released into the atmosphere.

Global oceans have absorbed a preponderance of anthropogenic heat over the past seventy years– some ninety percent of excess heat that was trapped in the earth’s atmosphere since 1955–that makes them perhaps the clearest single register of the extent of anthropogenic contribution to climate change. Yet our monitoring of sea surface temperature adequate, based on a points, hinders rather than help the scale of climate change that is occurring in the global oceans. It is perhaps a hard pill to swallow, that cannot be sugar-coated, but the deep reds of temperature anomalies present a stronger picture than the levels of temperature rise of the planet’s surface, and its detail demands far more unpacking and deeper drilling into its detail, to use a poor metaphor, to unpack in satisfactory ways.

It is otherwise hard to grasp the alarm registered in the header to this post. The very land-based tools of mapping that have allowed us to track landcover and agricultural productivity by GIS overlays may have been far less helpful in grasping the scale and of the anthropogenic modification of global oceans–and the to grasp the changes in global oceans that will help to process or come to terms with the consequences and scale of rising sea surface temperatures, and the contribution of anthropogenic contributions to rising global temperature that are at risk of changing the global habitat and our relation to the surrounding world at the levels we demand to understand. Fort he very tools of geographic mapping are ones that arose in terms of mapping from the perspective of a state–effectively, of seeing like a state–that led us to understand land use, as much as anthropogenic change. Yet the state has sold increased offshore drilling rights to many oil companies, in ways that have set the stage for planning offshore Direct Air Capture plants in sites like the Gulf of Mexico, increasingly treated by 2018 as a pubic-private density of point-based drilling sites, even as sea temperatures rise. The network of old wells abandoned permanently and temporarily on lands that the the US Government leased to energy corporations suggest a basis for the encouragement of a man-made shoreline tied to an infrastructure of energy extraction by 2018 that was difficult to change or every fully separate ourselves.

GIS layers helped engineer the most effective site of carbon sequestration in offshore regions of the well-mapped geological terrain of the Gulf of Mexico, already crisscrossed by a density of pipelines for optimal sites for low-cost offshore storage of optimal geologic suitability, despite the existence of clear risks of locating extractive industries offshore beside a wetlands that bordered on a rich marine ecosystem that was delicately stuctured as a complex oceanic habitat. The reference points for storing are the cities where workers at the new plants would live–Mobile; Houston; Corpus Christi; Biloxi–rather than the ecologically delicate salt marshes, wetlands, and estuaries that are critical to shorebirds, and spawning sites for crayfish, oysters, shrimp, mink and alligators. The choice sites for subzero storage of the coast of Louisiana lie within the offshore continental shelf, as if an extension of territorial claims of the well-mapped underseas regions long studied by the energy industry.

Favorable Locations for Offshore Storage of Captured Atmospheric Carbon, 2022

This may be the fate of the pointilistically mapped seabed, a weirdly compromised cartographic flattening of the offshore. For the oceans–the very life-giving areas from which we arose, and on whose edges human society long lived–offer the clearest register of the anthropogenic image of human-caused temperature rise, although, perhaps paradoxically or more probably circularly, the deeply anthropocentric systems we have mapped or registered land by a point-based system may be inadequate to register the impact of rising sea surface temperatures on planetary health.

–but how much our recent maps of marine monitoring are not evident as much in point-based registering of anomalies, but specific sites of ocean heat, with a troubling density off the coast of Japan, in the Persian Gulf, and in the Gulf of Mexico,as well as the Eastern Seaboard.

This contribution is difficult to map, or map to satisfaction as the result of human activities. But the stubborn nature of these deep carmine reds suggest, of course, a change that goes far beyond politics, and, if we might be glad for the light blue airbrushing on part of the Arctic Ocean and Greenland’s edge, the ice-free arctic and warming of antarctic ice shield seems much more terrifying signs of where we are headed, with a warming Atlantic–and Gulf of Mexico–a cause for alarm. If Canadian rock singer Neil Young dryly lamented in “Mother Nature on the Run” that 1970s would change the environment of the planet, his dreamy, druggy, hallucinogenic if anthemic call for help paralleled major breaks from the baseline of global temperatures. For from the postwar era through the 1970s, weather changes reveal the deeply disruptive nature of the global climate to which we are headed–and the step difficulties of visually communicating temperature anomalies. Were increasing surface temperature from 1900-2020 already hinting at the consequences of a failure to incorporate rapidly shifting temperatures farmers would faced by the late 1960s, in a 1970 album reflecting on how rising temperatures of the late 1960s and increased pollution created a powerlessness before a changing landscape, parallel to declining agricultural productivity?

If Young was not necessary a student of the Canadian Land Inventory, as a twelve year old set his sites to be an egg farmer–and to be a student of scientific agriculture at the Ontario Agricultural College to “learn to be a scientific farmer” after having tallied the improvised inventory of “Neil Eggs” as he organized sales of a chicken coop in close contact with Ontario farmers before listening to Chuck Berry, Fats Domino, and Elvis Presley replaced his raising chickens and selling eggs. The environmental anthem anticipates Young’s fierce opposition to factory farming since the mid 1980s, shunning venues serving foodstuffs from factory farms–venues “fed by factory farms.” But the oracular nature of the song covered by Patti Smith, after I’d written much of this blogpost, in Golden Gate Park, first made me wonder how the roots of the Canadian Land Inventory was unsuited to measure the changes in sea surface temperatures and indeed offer a meaningful narrative context for global temperature changes.

Extreme heat itself endangers farm workers–most U.S. farmworkers endure dangerous levels of heat three weeks of each year, beyond historical levels of heat exposure, growing to two months by the current century’s close per a recent study of the actual concentration of agricultural workers in America who will suffer from such a shift against the regions that are in upper quartiles for community resilience–suggesting the lack of abilities we will have to absorb or respond to such critical even if apparently “small” changes in temperature across the United States, shifting the productivity of farms in an era of climate change projected under different models or scenarios.

How to include people in the map, or how to include lived experience of other animals? We have perhaps all retreated into the comfort of our own buildings, retiring to contemplate rasterized images of modeled temperature changes in air conditioned rooms. The shifts in temperatures captured by eye-catching rasters offer limited narrative context to process such rapidly accelerating shifts of global surface temperatures. And if we presume to hope to “capture” carbon to turn back such rapid and unsustainable swings of surface temperatures in future years by continuing to allow carbon emissions, we are perhaps allowing ourselves to be the victims of cartographic distortions that fail to register the consequences of how oceans–in ways we have not fully been aware–have been absorbing up to 90% of anthropogenic global warming.

The arrival of July brought the warmest July on record–tempting a bitter riff on Stevie Wonder’s album by calling it “Hotter than Julys” about “making the earth a burning fire,” over a full degree centigrade–1.12°C (2.02°F)–above the 20th-century average of 15.8°C (60.4°F), raising questions of mapping anomalies meaningful, as the monitoring revealed a level of warming so beyond average that one might distinguish record temps warmest as something that the entire planet had not experienced, and that raises questions not only about the world, but our relations to the world–the Umwelt, that zoologists appropriated from idealistic philosophy at the turn if the twentieth century to acknowledge how different species used the senses to map external lived environments –that we are going to be forced to come to terms as our environments reached record heats.

The agency of animals in perceiving the world is less the point of this post, however, than the radical accomodation of Umwelt that such record shifts in ambient land and sea temperatures pose–and how we can recognize and communicate them beyond simple color ramps. The recent record marine temperatures raise questions of the warming of sea surfaces, in fact, that demand to be distinguished as a reservoirs of heat we have perhaps poorly mapped in describing the land-sea continuity of maps–a continuity that was long heralded as a modern innovation of terraqueous cartography in the early modern world–that might be less helpful when it comes to grasping the effects of heating oceans and the rising sea-surface temperatures and oceanic heat waves remote sensing tools currently reveal.

Record Land and Ocean Temperature Percentiles in July, 2023/NOAA

The pinning of heat to pixels renders not political polarization, but even more toxic disturbances of equilibria of global temperatures–but an even more bracing problem of organizing our relation to a rapidly warming world. These quite literal heat maps paint a scary picture of the complex distribution of warming across land and sea over a century of of warming, synthesized from the first era of fairly uniform data in global temperature maps.

But are the rasters tracking warming able to communicate the imbalances of these significant anomalies of global warming by almost three degrees in some spaces of the global ocean–and some a few regions–an increase that follows the yearly rising of surface temperatures from just before 1980. This was the very time that Young–son of a prominent Canadian newspaperman who as a daily columnist for the Globe and Mail had a knack for reporting–was chronicling quite recent spiking in global surface temperatures before 1970 when Neil Young called our attention to the new scale of pressures we put on the planet, at what would be watershed of rising temperatures that only escalated over the next fifty odd years. By some odd coincidence that may not have been that odd, Canadian government began to monitor land-use management in ways that would lead to the formation of early geographic information systems, as Canadian geographer Roger F. Tomlinson began using aerial surveys–using large-scale photogrammetric maps–to create visual information forms bridging computers and geographic data. By collating data about wildlife, forestry and the census to increase agricultural productivity, Tomlinson offered new ways of seeing like a state rather than like a farmer, in ways that claimed a benefit for farmers and farms across Canada..

But data on resources was privileged beyond data on warming–“heat” was not even a category of inventorying land information in maps, at a uniform scale and overlay, in ways that allowed “layers” to be read overlapping factors on a basic dot-grid, able to incorporate census data, that would reduce the manpower for resource mapping beyond the capacities of actual staff. Canadian surveys amassed databanks beyond human abilities to assimilate an inventory of land-use information, able to store information in readily usable form in a computerized inventory of overlapping layers jto process the scale of information overload in maps of environent, land use, and productivity that humans cannot process or analyze in an instant library of statistics stored on tape, but not maps–even as any point on the earth’s surface “can be identified by numbers” to allow a synoptic inventory of land quality to devise new practices of land use.

Tomlinson coined of “Geographic Information Layers”–long before he joined ESRI, down in he San Bernardino Valley outside of Los Angeles on the Pacific coast–as a public respository of land use. The weighty term itself predates a century of rising heat, however, and its inventories largely bracketed temperature and the effects of heat waves’ differently deleterious effects on land and sea. The Canadian government was presented by Tomlinson as the landowner akin akin to a farmer forced to make decisions but who had “hasn’t got too much idea about the climate” or the water on his property he has just inherited, forced to make decisions about how to plant the right seed for his family. The very same questions, he explained in a classic CBC promotional short, were pressing to addressed both by the farmer who inherits a plot of land, but can be extrapolated to the nation’s management of millions of miles across Canada in an inventory.

The result that “the map has been converted into numbers” allowed readings of land quality at every hundred feet across the country, now readily accessed in hours, stored on tape on a grid aligning census tracts, water rights, and the fertility of the soil, placing jdata in the hands of decision makers in a public library of land. By replacing the human eye’s relation to landscape by an interface of soils, climate, topography, wildlife, forest capabilities and census tracts by subdivision in a profile of the nation, map layers were analyzed at multiple scales to zoom in on local land use at points and polygons,–

Saskatchewan’s Land Capaibility for Wildlife, Canadian Land Inventory (1976)

–merging files and coordinates of the Canada Land Inventory that have provided abasis for optimal land use and government investment that offered a tempting basis for similar inventory of the nature of atmospheric changes on a global scale. Yet a farmer’s local knowledge is different in feel and texture than the point-based layers Tomlinson optimistically advocated as a national mapping model–in ways that is not captured in the massive inventory that classified the land.

But the land use inventory presumed a stable definition of “nature,” that he current escalation of temperatures when Neil Young composed his anthemic song about Mother Nature being “on the run” as a fugitive or convict around 1970s, as temperatures started to rise yearly, shifting the crop yields in the data that Tomlinson measured for he Department of Forestry and Rural Development by stacking up layers that would align point-based data for cartographers’ benefit on any land-map.

Neil and his father Scott Young famously lived outside of Toronto, on an Ontario farm, and would have been aware of the Land Use Inventory, but also of the problems of a shifting sense of nature that it did not easily capture in its discrete point-based layers of information. Yet the rising surface temperatures of the late 1960s and later years that won a large and continued audience for Canadian guitarist Neil Young’s anthem in his first great solo record was rooted on working on a farm responded to the increasing anthropogenic nature of rapid temperature change–as much as the fears of nuclear apocalypse and technological advances–that inaugurated an escalation of above-average land temperatures through the first fifth of the twenty-first century far beyond what Young himself had feared or envisioned, difficult to reduce to but a single layer of a map.

We are not cognitively attuned to imbalances, and dramatic departures from the status quo. If cognitive biases that lead us to prefer status quo relations where things remain the same are common basis for poor decision-making, the desire to prefer that things stay the same is an especially pernicious error in assessing the anthropogenic contribution to climate change: we allow ourselves to be seduced to maintain the status quo, to minimize risks, but have occluded the imperative and huge benefits of reducing the disruptive cascade of ecosystemic shifts of such consequence to be impossible to process in terms of the two-color schema of red and blue.

It is hard not to worry that the tools of registering such rapid shifts of surface temperatures offer a poor sense of our relation to the natural world–or help to clarify the rapid shifts in the biological of the world that will be and are experienced by other creatures. For the stark shifts of temperature changes map a misleading balance sheet of environmental change that is oddly distanced from the relation of organism to the planet, or a tally of benefits and costs that occlude the relation of organisms to the to the surrounding world, that should be the true centering of any understanding of climate change. The compromised relation to surrounding environments that the plotting of value in underground deep-sea energy reserves is a distortion privileging the point-based location of value, removed from the oceanic environment or critical dangers of warming waters of the global ocean waters. As the habitats of oceans shift in irreversible ways, the ability of creatures to relate to the world, or to perceive their surroundings, changes, and we are caught, as a deer in the headlights, without a clear way to grasp either the scale or effects of changes in the global ocean.

We trust we still have time to withhold judgment–as if fears of losses of once abundant petrochemicals can occlude an appreciation of potentially hugely favorable gains, driven by fears that declining oil prices might hinder profits to drill over 50-60,000 more new oil wells annually–

200714 Rystad Global Drilled Wells

and as the expansion of inland drilling in the southwest’s Permian basin has continued to expand of every increasing depth, reaching unwarranted heights, driven by demand for profits and continued petrochemical security, driven by the illusion of an abundance of underground petroleum reserves. nd the increased depletion of near-shore wells that were drilled off the Louisiana coast in the Gulf of Mexico back in 1938 have led to the growth of an offshore archipelago of 3,500 platforms off the continental shelf of the United States, and along the continental slope, leading to a boom in wells under a thousand feed of water on federally leased land–deepwater and ultradeep rigs, whose risks challenge notions of environmental responsibility in a larger network of active gas and oil pipelines, processing plants and offshore structures in leased lands on the outer continental shelf.

Perhaps we have little clear ways of registering the scale at which anthropogenic contributions add to the warming of the global ocean, or of planetary seas. We have no clear basis to represent this growing contribution, let alone to narrativize or narrate our own relations to the rapid acceleration of climate change and its multitude of consequences of a warming world. Our maps are not at fault, but have their limits as they reify the conditions we live in–rather than our contribution to them, whose specter is perhaps all too evident in the world’s largest gulf, a marginal sea of the Atlantic whose seaward boundaries provide one of the greatest challenges of coastal management.

The Gulf of Mexico is itself an anthropogenic space, where’s the seamless bridging of land and sea: as well as a proof-of-concept of liabilities of mapping a continuity of land and sea by leasing of federal lots for platforms for extracting oil and gas of increasing depth, far deeper than five to six thousand feet below sea-level. The expansion of deepwater mapping has grown dramatically since 2000, by energy companies growth eager to match demand for gas and oil as abundant in “national” waters; the government is eager to license to ensure the ability to “keep” energy prices down. If the current plans to invest billions in unproven tools of “direct air” carbon-capture promises a reduction of greenhouse grasses and new commitment of industry to greening, by “vacuuming” emissions at their source,” that would allow us to address the “carbon problem” with no change in our consumption of fossil fuels. Even as it promises of erasing the onerous emissions are unproven the promise to allow carbon dependence is widely promoted by energy companies: public funding of Carbon Capture and Sequestration would sanction the continued expansion of the largest offshore energy infrastructure in Texas and Louisiana, and boast the adoption of the best mapped geological region to sequester captured carbon for 559 BN metric tons of carbon storage.

Offshore Carbon Sequestration in the Gulf of Mexico/Helen G. Prieto 

The promise of investing public funds in a boondoggle of corporate “greenwashing” is promoted as the “evolution” of a new American landscape of Carbon Capture and Storage (CCS), by subsidizing Occidental Petroleum to build corporate-sized “direct air” carbon capture and storage plants ready to imagine as a a new national infrastructure dedicated to construct “hubs” of carbon capture to be piped to “injection” sites where it might be stored or “sequestered.” Planned carbon “sequestration” projects are paired with green-lighting bids for offshore sequestration on federal lands lying in one of the most studied geological basins and potential sinks, the Gulf of Mexico–a site of expansive offshore energy infrastructure that is currently promoted as “the largest volume regional geological sinks in the United States for large-scale Carbon Capture and Sequestration.” The region that has a large number of depleted oil fields, already owned or leased by energy companies, essentially, is promoted (and extrapolated) as a bonanza of Gigatons of carbon storage.

The continued mapping of the man-made offshore environment of the Gulf of Mexico is plotted as a prime site to capture of carbon. The transformation of the Gulf of Mexico to a site of future carbon storage fulfills a fantasy of absorbing fossil fuels’ pollution from the skies without reduced dependence on petrochemical fuels, detracting attention from the very edges of marine habitat oil and gas extraction threatens. The very premise of “Direct Air Capture” takes eyes of the maps of global warming and many modeling of the effects of ocean warming.

Proposed “Direct Air Capture” plants would imitate the very functions performed by the very coastal ecosystems–salt tidal marshes; kelp ecosystems; and even the open ocean–or are argued to do so on a broader scale than the sequestering and absorbing of one to two tons of carbon per hectare in existing salt tidal marshes, or the Florida Everglades, whose mangroves and peat soils have huge carbon stocks, and carbon sinks valued at $3 billion, if reduced by pollution and climate change. Spending over $6 billion in carbon capture projects along the Louisiana coast to sequester the carbon produced at refineries, making the state’s coastline into the carbon capture capital of the American South–but suggest the abstraction of costs and balances of carbon in maps of unproven possibilities of capturing carbon across the state, even as ocean temperatures rise at rapid rates.

 Industrial CO2 Emitters against Potential Biomass Residue Availability/Carbon Mitigation Initiative

Yet the seductive promise and premise of carbon capture is perhaps best understood as a way of keeping the actual problems of anthropogenic global warming that has already shifted the qualitative character of our global oceans in increasingly irreversible ways. The operational metaphor of “vacuuming” carbon at sites of emission is billed with unwarranted optimism as a technological fix for states that are notable  CO2 emitters who produce potentially dangerous biomass residue. The trust in technological fixes claim that coal-fueled plants can continue to burn brightly, but stored underground, as more petroleum and gas is removed from the offshore fields by “blue hydrogen” or “green fuels” that claim energy companies can lower their carbon profiles–by giving license to further pollute, and place continued risks and environmental stresses on the Gulf of Mexico. While the coastal forest in the watershed of the Mississippi as it enters the Gulf might sequester two to four tons of carbon/acre, annually, if rehabilitated as a “blue carbon” reserve by conserving, replanting, and restoring coastal forest, black mangroves, and receding salt marsh.

Yet investment flowing to carbon capture diverts funds of energy companies from projects of coastal restoration, that is pressed to reduce massive emissions of greenhouse gasses by energy companies, as we continue to burn increasing quantities of extracted carbon fuels–a decade after the goals for reducing emissions were set, and carbon emissions began to fall nationally. Might we not better call out the illusory promise of DAC not blue-washing, obscuring the effects of prospecting and extraction from global oceans acutely felt at the delicate habitats of coastal edges? For only by looking more at these edges can we fully come to terms with the anthropogenic environments we have created, subsidizing energy companies at the hopes of reducing the prices of energy in national markets in responsible ways, and come to terms with the blinders we have kept on the extent to which we have redesigned the coastal environment of a our “national” ocean of underseas energy reserves for national markets.

The building of projected “Direct Air Capture” plants at a rate of thirty a year from 2020-2050, per the International Energy Associations, and fifty a year from 2030-40, and forty 2040-50, would allow global energy consumption to grow, and the petrochemical plants to expand with them.

Would not such plants–and areas for geological storage of CO2–not be a bonanza for energy providers, as their prohibitive cost would demand public funding to delay and eventually reduce their huge cost, to allow air travel to be a climate-neutral, or of net-zero emissions, while it relies on carbon fuels, and the plants’ own costly operation be run either by renewables or non- or low-carbon fuels. The geography of “renewable energy sources” and “CO2 storage” provide a numbing assurance that erase the salience of the very useful artifacts of these global anomalies, treating the world’s surface as a smooth repository for “storage” of the gasses that accelerate climate change.

Existing Direct Air Capture Plants and Planned CO2 Storage Facilities/International Energy Association

If the hundred and thirty DAC plants are allowed to proceed, they are argued to guarantee net zero emissions by 2050. But the promise that the plants are argued to gain efficiency and reduce costs only by a huge investment of funds in an unproven technology, although we have already begun to cataclysmic effects of a warming oceans. Are we not being invited to adopt a selective amnesia of the huge effects of off-the-charts anomalies of land and sea temperatures and their effects?

This post, ranging widely over ocean space, seeks to given more materiality to the screen-like maps of ocean anomalies that have provided the most common media we rely on to grasp climate change with the necessary detail or grasp. Specific sites provide a basis to drill down these global anomalies onto on a local level. For only by doing so can their dizzying array of detail be fully appreciated and taken stock of for its effects, and the scale of anthropogenic change be appreciated. The useful “baseline” of a land-sea temperature might be appreciated as an artifact of postwar globalization–transverse global grids having been adopted roughly contemporaneously by German Wehrmacht aerial photography and the United States Army Corps of Engineers as the coordinate reference system for global war, due in part to the professionalization of cartographic corps and the challenges of mapping across borders in World War I, pragmatic questions of firing and land-sea coordination, as well as working across the often separate and distinct coordinate systems of European nations. But the very illusion of continuity of land and sea temperatures are less helpful to appreciate the scale of anthropogenic climate change we have witnessed in recent years and over the summer of 2023. Has the imposition of a gridded map of energy extraction helped to ignore the sensitive and intensely rich habitats of the shoreline and coast–watersheds, wetlands, as marshes–as areas of vulnerability and protection?

The question of linking land and sea temperatures in a smooth surface was inherited from the mid-century postwar era. It has informed the presuppositions of weather maps, and is common to the mapping of extreme global temperatures. But the realization of the intense levels of heat stored and sequestered in ocean waters this summer has sent a jolt through the mapping of rising sea-surface temperatures of extreme intensity far beyond normal, raising questions of how to process a global warming monster of heat stored offshore as it presses against the thin margins of cool coastal waters that crash against California’s shores,–are as terrifying as the maps of recent fires’ spread in an overly dry state, or maps of low groundwater levels in California and other regions. Although the California drought in over, it seemed oddly apt if deeply disquieting that the ocean heat wave now threaten the states’ shores in marine infernos lying off of our green shores.

Category 4 (Extreme) Marine Heatwave off the West Coast of the US, nearly 5°C (9°F) above Normal/NOAA

The intense heat wave satellites recently registered off the coast of California, where I live, was unprecedented as it was a weather system where water temperatures peaked almost ten degrees Faherenheit above mortal, has developed off the West Coast of the US, with water temperatures peaking nearly 5°C (9°F) above normal. As much as the Category 4 (extreme) marine heatwave was an event of local shock, it had been advancing across the Pacific Ocean for them. Rather than registering a deceptively flat synoptic view, the image of marine monitoring is a story that exists at multiple scale, the seasonal weakening of colder deep sea waters that cool the coasts in upwellings may bring significantly warmer waters off California’s coast than habitual for Pacific waters, the “Category 4” Marine heat wave risks provoking offshore harmful algal booms, compromising coastal ecosystems, and causing die-offs in coastal waters of mussels and other intertidal species that risk upsetting the marine food web.

The cognitive confusion of ecosystemic disruption is hard to get one’s head around as it exists contemporaneously at multiple scales. Can one map, however, within those layers, the contribution of anthropogenic influences on these stories of cataclysmic change? The complexity of telling a story about ocean warming–let alone a powerful or positive one–seems to be the difficulty of shoehorning the global scale of surface temperature warming in readily graspable terms. While we live locally–mostly–and perceive temperatures in the atmosphere around us, or the immediate ambient surroundings, processing the terrifying range of global temperatures as anomalies places cognitively demands on us as we contemplate the prospect of weather systems we have no means of controlling, if we are wrong to bracket weather systems among circumstances beyond our control. The difficulty of processing the dissonance between how heat is stored and processed on land and at sea, and indeed out the extent to which ocean waters are storing and sequestering ocean heat may offer the clear-eyed appraisal of the extreme weather systems that have shaped the summer of 2023. The inability to come to terms with the cascading effects of such anomalous warming on such a scale is undeniably existential, and we don’t narrativize existential issues well.

Our maps seem to be challenged, and of little help. The very ellipsoid reference system featured in our global weather maps threatens to distance itself from lived world as a pixellated screen by which we witness global warming with alarm, forced to seek moorings before deep red rasters of alarming anomalies, however, that quite convincingly seem to supersede the geopolitical borders of the nation-state, if not raise questions of scales that nation-states seem unable ever to resolve. The red and blue coloration of the regions of America, set in an eerily similar terms to a map of partisan divides, are even less easy to come to terms–if with effects even far more disempowering.

The recent rasterization of our ocean maps–we map less bathymetry than temperature anomalies in the daily coral reef watch–recast the ocean a color ramps than we have seen before. If the massive coral bleaching of this summer has become a token of the sudden nature of ecosystemic collapse of global warming, the loss of coral reefs a microcosm of climate apocalypse, pressing us to create stories and gain a grasp on what has been happening with our oceans and ocean temperatures as they start to warm in dangerous directions across the north.

The liability of such raster maps may lie in their eery ethereality: a pixellated powder distancing us from the materiality of climate change, rasterization is an eerily immaterial way to view global warming unhelpful in its terrifying immateriality, as if blocks of predestined pigment sprayed across the ellipsoid outlines globe at a distance and from on high mark the bleaching of ocean life. It is terrifyingly inappropriate not only in its lack of narrative–if the story is tragic, and it is existential to boot–but cognitively disarming as it is removed from any material basis, but the map is haunted by a lack of distance, wrapping the surface of a globe as if spray-painted across the flat ellipsoid disk, which we struggle to map onto the particulars of the loss of life in the global ocean. As m much as the dark rids of rising anomalies are located in oceans, it is difficult to link the flousescent colors to the tragedy of the blanched reefs of the Florida keys, whose deathly whiteness of long flourishing staghorn coral, and quite vulnerable elk horn coral, seem blanched if not boiled in the heating up of the ambient coastal oceans of which we are suddenly all shocked observers.

The absence of boundaries and sovereign spaces from the map of temperature anomalies tells a great lie of the uneven distribution of warming, apart form the different contributions of individual nations to the release of greenhouse gasses and carbon fuels, and continued extraction of carbon-based fuels that have been the predominant contribution to temperature change. If the ellipsoid without national borders is indeed an icon of globalization, it too handily lacks any accounting or inventory of the contribution of greenhouse gases to climate change. Global warming was long the greatest treat to coral reefs of global oceans, as algae leave–or “jump ship”–from the living tissues of coral polyps, even as ocean acidification has slowed the growth of coral skeletons needed for a vibrant ecosystem. If coral blanching has gained heightened attention as a die-off in our coastal waters, fed by the dramatic images on globally streaming media, global oceans have already been widely impacted by warming since 1950, dramatically decreasing the biodiversity of these delicate and unique habitats in oceans by a stunning 63% since the 1950s. Ocean heat waves of direct anthropogenic creation have dramatically triggered mass coral bleaching events of reefs already compromised by overfishing and inadequate ecosystemic protections.

Global coral reef cover declined quite dramatically below the baseline in the early 1960s in ways witnessed by indigenous cultures who sounded alarms for conserving reefs by a more sustainable blue economy, as if monitoring of reef ecosystems was only registered as coral bleaching approached national waters of economically developed nations. As bleaching has entered the EEZ’s of developed nations, we would do well to take stock of the deep dangers of the myopia of global warming. The scale of global diminishing of reef cover by over 50% from 1957–2007 is parsed by shifting rates of loss of coral coverage ranging from 4.7-6.8%, even as Caribbean countries, Thailand, or Japan saw modest increases in reef health, didn’t gain global attention until it arrived at our geopolitical doorstep, even if long feared. Even as some 90% of living corals in global reefs were lost from 1980 to 2020, projects of coral restoration–suspiciously funded by the United Arab Emirates. But as the recent spate of uncontrolled tragic wildfires across the island of Maui have led to a sudden worry about the entry of carbon into coastal waters on rare coral complexes of long tourist attraction of its pristine beaches, the threats to coral ware only seen once they are on our doorstep. Maintaining the array genetically diverse varieties of twenty species of coral, of over 1,3000 putative genotypes, poses challenges not only for marine sanctuaries but a globalizing world as oceans warm, driven predominantly by global consumption of fossil fuels.

Changing Percentages of Coral Cover In Exclusive Economic Zones, Tyler Eddy, et al, 2021

The shifts in the blue landscapes of coral cover suggest that the cataclysmic collapse of reefs off of Florida’s coast was not so sudden or unexpected on a. global scale. Yet ecological safeguards and monitoring were not yet attended This post suggests some ways to re-materialize those anomalies. By rendering them not only as a wash of rather inevitable ineluctable tides wrapping around the ellipsoid, those pixels might be more clearly cognitively rooted in material geographies of overly rapacious petrochemical extraction of petrochemicals that has given new meaning areas lying in the offshore those coasts. For the spaces that suddenly gained new materiality in the postwar period of a mania of mapping that led to the reordering of the offshore as a national energy market as an abundant mine of carbon energy for the nation led to an accelerated offshore prospecting, as offshore seabeds gained new materiality in maps as a site able to be extracted for growing energy markets that redefine the seabed and seepage of gas and oil into the global ocean.

Yet the immateriality of our rasterized maps of temperature may distance us from our impact of petrochemical harvesting from the largest ecosystem on Earth are heavily impacted by anthropogenic climate change. Their distancing helps us forget that how, on a local to global scale, it is not only the oceans that have formed a reserve for adverse weather systems, but how oceans have long absorbed human-made heat, and change the very shortest that are among the most diverse ecological areas hosting vital ecosystems, whose stable if quite delicate structure may be a site where changes in climate are disproportionately felt. The point-based pixellated maps of measuring temperature change are dangerously thin as they are distanced from the environment of the ocean, and near-coastal, as well as the coastal environments whose wetlands are so critical to shorebirds, migrating birds, coastal species, and other wildlife.

Nearly 400 species of bird live in the Gulf of Mexico–a “super breeder” environment and keystone habitat–of high avian intensity– from the snowy plover, egrets, spoonbills, to bobbies and frigatebirds who nest in the Southern Gulf of Mexico. These bird populations–and other neotropical and neoarctic migrating populations who use the Gulf as a critical flyover stop for feeding. The coastline may be more threatened by plastics and fishing line than oil, the region already threatened by man-made coastal development–it was not even regarded as a critical areas of wetlands threatened by saltwater intrusion (like northern California’s Sacramento Delta or Delaware) or industrial pollution (as New Jersey)–if that changed by 2010. But the sensitivity to coastal development and petroleum extraction revealed by the Deepwater spill with an immediacy few had imagine, leading to a short-lived push for safety standards for oil and gas to protect threatened flyover habitat by which many migrating birds are nourished as they travel north.

Threats to Migrating Birds in Gulf Of Mexico by Population Growth and Coastal Development

Despite the considerable power by which rasters place into relief a synoptic screen of regional temperature anomalies, their totalistic scope is difficult to parse with the necessary patience and specificity. They invite us to register temperature shifts in the global oceans expected to trigger a change in near-coastal habitat, as if the shores–that site where man historically evolved, as well as one the first sites of mapping, seems in danger of being rewritten, in ways that should shift the focus of our worries from sea-level rise.

When Solnit argued we are paralyzed by our inability to tell a story about climate change, she raised objections of failure of narrative is one of not being able to see a possibility for change, or a livable future: in arguing that we risk being paralyzed by a lack of ability to tell a story about climate change that allows us to see clearly, or creatively enough to understand our power to retain a sense of agency before the massive data of climate change, she may be suggesting we are at risk of being cognitively overwhelmed by and drowned in widely circulating stories of die-offs due to warming, as so many desperate signals of all-but-inevitable climatological defeat–in the polar caps, for example, diminished sea ice thickness create a surplus of ice-melt sends far less salty, warmer water into the global ocean, threatening to shift the colder deep-water masses that drive ocean circulation.

Yet is this not also a failure to map the ocean waters in ways that do not leave us drowned in data? Is the circulation of deep-water masses so remote to be difficult to comprehend in how super-saturated colors that call our attention to global warming, of which the appearance of indigo is so striking and so terrifying–as if blue waters peak through the thin ice shelf on the edges of once floating ice. Does the electric blue swirling about the edges of the arctic shelf that call attention to our eyes as a dangerous abnormality not also register the thin ice on which we collectively stand?

We struggle to encompass both the immensity of a global story that does not drown us in disempowerment. We are indeed acutely aware of lacking a story that presents options for responsibility; we have trouble coming to terms with how to find a place for the local or the individual in totalizing maps whose projections cow us before the gears of an altering climate, their data lying on the surface, as it were, in haunting spills of color whose apparent immateriality makes their actual effects difficult to grasp.

The saturated rasters pixellate a world indelibly haunted by climate change, pools of dark ink swirling to create a tipping point of inevitable rupture from the past. As much as mark an environmental “tipping point,” the effects of global capitalism is to conspire to delay ecological consequences and ruptures, effectively testing nature’s ability to absorb shocks as it teeters toward potential collapse. By casting the thinning ice shelf on the edges of as opening an all but inevitable cascading of still greater, future dangers–projections of sea level rise, coastal flooding, erosion, habitat destruction–we fail to render how technologies of energy extraction have changed the ocean, or the long-term testing of the elasticity of nature by testing the limits of the natural world to absorb increased waste and the detritus of consumption, while extracting and appropriating natural wealth of petrochemicals as a national bounty that has no effect on local ecologies.

If the testing of the first atomic bomb by Robert Oppenheimer was long appreciated as heralding modernity in New Mexico’s desert landscaped; effectively black-boxed, the story of the stresses that it exposed the environment and local inhabitants went unquestioned. The increased effects of anthropogenic pollution are however, as Kohei Saito argues, in a rather telling ecological critique of capitalism, no longer able to be absorbed in the world; we attempt to register the shifts in data in maps, all too often, without trying to tell a story of the inroads of natural wealth or the possibilities of environmental regrowth, if not obscuring the very possibility.

The masses of data in current projections of temperature rise appear all too inevitable–unable to be assimilated to a story, because they seem to truly allow little place for us in the world, or might take our focus off of the hopes for diminishing the accelerated sea-surface warming that may alter global ocean circulation and the rise of the global ocean. Indigo tracery served as hieroglyphics of a future melting ice sheet in 2019, in the cutting edge NASA satellite photographs of Earth Observatory that revealed a melting midsummer pooling of indigo waters in ICESat-2, the most sensitive tool yet to measure the surface of the world’s largest ice sheets in Greenland or Iceland–regions that threaten to add significantly to sea-level rise in coming years, as the world is losing over 200 billion tons of grounded ice annually by the thinning surfaces of ice sheets–as if blue indigo ink were pooling on their surface.

And a clipped elevation raster with a blue color ramp of Antarctica, enlisted indigo to register the increasingly low elevations where the Antartican ice shelf currently meets the sea, as a saturation of deep indigo of lower elevations at the ice shelf’s shore. This indigo demands more materiality.

Is it trying to recuperate the pristinity of the indigo ringing the arctic poles in the very first polar projection by Renaissance cartographer Martin Waldseemüller? The haunting Waldseemüller engraving of the arctic oceans and channels feeding unknown blue waters harbor multiple seas of its own, themselves with islands of uncertain edges. The cartographic rebus–itself a microcosm of the compass–offered an enticingly new vantage on a spherical world–imagined a northern ocean still not sufficiently mapped at whose center lay a giant magnetic mountain at “due north,” from which four flowing rivers combine functional reference points of four cardinal directions with the microcosm in an convincing conjectural cartography of areas few Renaissance explorers explored save Martin Frobisher and James Davis, whose nautical accounts were the basis for invented polar isolario not rendered or appreciated with true interest in most Renaissance planispheres.

The newly mapped “glacial ocean” was no longer the site of abundant fantastic islands, but a separate sea lying as if in wait above the northern edges of the world’s continents, whose frozen islands whose edges had not yet been fully mapped, was a remnant of “T-in-O” microcosms, four frozen rivers flowing beyond a multitude of islands whose edges were, enticingly, not yet mapped, and might well be, as Waldseemüller had wanted the readers of his map to imagine, to be inhabited by pygmies. The fantasia of light blue waters and edgeless islands around the poles was one improbably inhabited by pygmies, whose flower-like perspective on the world opened an iridescent fantasia on map colors, unlike Gerardus Mercator’s maps–the reedition by the Amsterdam based cartographer Jodocus Hondius was more of a hybrid conjectural cartographic rebus, with edges of continents of North America, Asia, and Europe peaking out of the sides with part of California, as if inviting readers to puzzle their assembly of an unseen perspective of the Typhonian, Scythician, Mirmanskoi, Petzorke and Hibernian oceans in the northern glacial sea–Nova Zembla and the Straits of Anián, and a giant whirlpool that threatened direct navigational access–each with a heritage in Russian literature of Vladimir Nabokov or Straits of Anián, to construct as an imaginary division between North America and Asia that offered grounds for early modern cartographers to believe in a Northwest Passage. The current blurring of the pole driven by greenhouse gasses have grown in a new era of globalization, poised to re-blur the edges of arctic and antarctic ice shelves.

Gerardus Mercator, Septentrionalium Terrarum (1606 edition by Jodicus Hondius)

Waldseemuller’s cartographic conjecture of semi-frozen regions of the Northern Pole left its indelible imprint of indigo in recent remappings of ocean currents and the polar ice shelf. If the fanciful assemblage of a quadripartite pole nestling the stony magnetic mountain–a “black cliff of immense height” that created the very same due North on which Dutch navigators had relied was in fact nested in oceans, ringed by mountains just outside where we now place the polar cap, inside the red perimeter of an arctic circle ringing the Mare glaciale, as literary as cartographical space.

At the time, many assumed the pole itself featured a giant, magnetic mountain.

Can its imprint of indigo also be an invitation to invest new materiality in a region for which we risk defamiliarizing in rasters? Is the material basis of indigo–a distinct new color of the seventeenth century, not only for Newton but as an abundant luxury import from the Indies, a natural dye–“true indigo”–that was the product of increased global commerce, and perhaps a hint of the new materiality? Deriving as a modern hue of textiles born from a global Atlantic exchange, imported by Spanish colonists to plant and harvest in plantations of the New World, from the Carolinas to Guatemala,–a boom market for in natural dyes was magnified in Europe’s textile wars, and the fueling of its industry by new fashions for striking colors. Unlike the celestial blue of lapis, the market for the trade in textiles was based on a commoditization of colored fabrics that, far from being associated with celestial blues, were signifiers of status in a market of woven commodities.

Demand for textiles was the economic engine of a first era of globalization, from beyond the Indian Ocean to the Americas, as demand for fashions grew capital in seventeenth-century transatlantic trade. If the burning of petroleum and petrochemicals has been by far the greatest engine of the Anthropocene, the dependence of the current age of globalization on unbounded markets of petrochemical extraction that have created an indelible imprint of Anthropocene–extending from global oceans marked by floating gyres of garbage patches to microplastics in ocean waters and the increasingly impreganated plastic seas to the textile fibers detected in human breast milk.

There remains a dangerously deep risk of de-familiarization of the planet due to data overload. These global trends are so cognitively overwhelming, even in an age of globalization, the rising tide of ocean temperatures seem destined to overwhelm, and not only on the coasts and coastal environments. We have trouble trying to sense this change, as temperature anomalies become the tool in trade to represent an extreme overload of heat burdening the world far from the equator by a blanket of unprecedented warmth both off the charts and physically hard for humans to sustain.

The appearance of “excess heat” that ranged considerably above average for late July, which was literally hotter than most all Julys since Steve Wonder’s nineteenth studio album was released–enormous stretches of six continents were as much as fifteen degrees Fahrenheit warmer. The powerhouse graphic sent a global alert to caution we were in historically unchartered territory.

The current calculations of heat stress on the human body in direct sunlight–“wet bulb temperature”–is a measure of heat stress, is in a sense the reduction of that temperature change to the basic common denominator of the human body. Although the point-based assessments might map to isotherms, in a broad way, the outliers might be so extreme to render this pointless. And the current water temperatures in western Florida of over 90°F or 32°C in the Keys, three or four degrees greater than land temps.

The land is both inhabited–and we are suffering from overwhelming excess heat. But the record heat absorbed in the global oceans and rather unprecedented effects of rising Ocean Heat Content—-water temperature change times the density of water times its heat capacity–has led the Gulf of Mexico to rise 1.8°F since 1950, and in May 2022 almost two degrees Fahrenheit above the 1981-2010 average, fed by the deep fast-moving warming waters that long intensified the Gulf’s heat. (The red is here denoting the rapidity of the Loop Current that enters the Gulf from the Western Caribbean; the indigo denotes the relatively still waters along the coasts and semi-enclosed sea, shown in a combination of rasters and vectors of warm Loop Current’s sudden influx to the Gulf.)

The recent alerts that NOAA issued to alert the Florida Keys to the threat of widespread coral bleaching in late July transform the once-bucolic waters off the sleepy southern Florida coast into a dark red danger zone may make coral a surrogate for humans. The rasters that shift attention from the land offer a salutary alert and caution, but their saturated colors are hard to process without alarm.

The recent risks of coral bleaching in the Gulf of Mexico’s waters may be so powerful not only as coral is a keystone species, of broad impact across the ocean ecosystem, whose living reefs offer food sources that promote or foster biodiversity in tropical waters, whose very structures and food sources promote biodiversity, and allow the ocean waters to function as a carbon sink, the image is apocalyptic as a record of the declining vital signs. Are corals a proxy for wildlife from migrating landbirds to a vast and vital coastal ecosystem centered in wetlands, whose habitat and food sources would be threatened to be compromised by petrochemical accidents or potential spills?

The density bird stopovers along regions of the shore and wetlands map an area most vulnerable to maritime spills or pollution. A single spill would compromise a vital stopover habitat mis-mapped as a shoreline, and not a resting and feeding site for birds making returns north after a thousand mile migratory flight to search for food that will equip them to continue their journey north. If the striking density of bird stopovers in the Gulf of Mexico might suggest a value that is erased by the mapping of value in offshore lots leased for excavating oil and gas.

The red rasters hemming in Florida’s coast recall the unhappy ending of the father and son who wander across a post-apocalyptic America in that first gothic novel of climate change, The Road, which eerily doubles as the first novel of post-9/11 America. Father and son travel on foot to an ocean whose surface is not at all blue, as promised , but reveals itself in the book’s final pages as a “vast and shifting heavily like a slowly heaving vat of slag,” transformed to a “the endless seascrawl” as if itself rewritten. “I’m sorry it’s not blue, he said,” the father manages, whose son, expectations long diminished, replies “That’s okay.” It is not the coast of Florida, but it might as well be the coast of a massive coral die-off, of dead zones, littered by detritus of nuclear or atomic ash. But this is not the story we want to tell, invoking a leap of faith at a gray, grimy mournful end.

This is one, archetypical, story of climate change, and not the one we want to have. It is a story of love and despair, as grimly post-apocalyptic as one might imagine, if deferring the apocalypse, but only not to tell us how it ends, but to suggest something akin to spiritual if not religious consolation. That is, perhaps, as far as it gets as a story of hope. But the alerts NOAA released seem increasingly of a sea shorn of life, if not yet covered with post-apocalyptic ash, registering an apocalyptic reality that might only find redemption, William Gibson has suggested, in a more recent twist, we might only be spared by by a virtual surrogate alternative reality.

Regional Heat Stress Map for Florida Keys/Coral Reef Watch, NOAA (July 26, 2023)

The threats of the absence of equilibrium in such a map fly directly in the face of an image of hope, as well as the recommendations the International Energy Agency planned as a roadmap to net zero emissions of approving no more new oil or gasfields for development from 2021. Not only the United States have granted far more licenses to fields, many of which are offshore and an increasing number in the Gulf of Mexico–if the Gulf of Mexico became regarded as a “national ocean” from the 1950s, new wells may be slated beyond national waters.

If April is the cruelest month, as the world regenerates, “breeding lilacs out of the dead land,” June is the month of pronouncing on impending anomalies of global melting as lilac drifts to the northern climes. If lilac offers the color for cooling waters, in most ROYBGIV color ramps, each summer, lilac seems to be moving farther and farther to the poles, as the equatorial regions approach 35C, the withdrawing of cold water to the poles is in a sense an occasion of mourning, with Whitman, a sense of loss. Newton may have introduced indigo in the rainbow spectrum–as Thoreau was to give prominence to Cerulean, another tertiary color–to affirm the sacred geometry of the rainbow, after first finding five colors and then adding orange, but its prominence in the Opticks (1704) denotes the rim of warming waters on the blue-violet edges of arctic regions, levels of lilac in the north suggest the scarcity of cold, cresting the arctic regions of water where ice melts. May be the uncanny warmth of indigo has made it into a default of warmer ocean become an omen of warming waters that lead to an unstoppable glacial collapse, not only in the west Antarctic, as indigo seems the apt color of the danger of a feared potential rise of global ocean-level by over a half-meter, and triggering a rise of several meters more–and the fear of an inevitable retraction of the edges of the Antarctican ice shelf of global consequence.

And the uncanny warmth of the near-arctic oceans, ever warmer in recent years, as the warming underbelly of floating ice, seem a fearful record of the warming waters set to trigger large and potentially sudden changes in sea-level rise. Even if we are confounded by alarming carmines and deep reds in raster maps of landsea temperature anomalies in recent months, the warming waters of lilac and indigo speak rather deeply to the warming of arctic and sub-arctic waters.

Does telling a potted but pertinent story about indigo as color offer a surprisingly global tale of markets and man-made world? Indigo has a history, and the history of indigo as a plant dye that entered European luxury markets as a craze for vividly colored clothes in the seventeenth century would boom in the eighteenth, but made it the most noticeable color of note to the English eye when it was included in the spectrum in the Opticks (1705), when it had challenged the longstanding use of woad to color wool. No doubt reflecting the dominance that material versions of blue had secured in the market for colored fabrics before the discovery of Prussian Blue in the early eighteenth century, a precious resource and prime product of harvests in colonial settings in the West Indies used in the textile industry whose importation was already a prized if not dominant import from 1650 in the transatlantic trade from Spanish colonies, “the most famous of all dyes” no longer arrived from India, Newton would have been familiar with the stability of “true indigo” as a universal dyestuff, if one deeply compromised and affected by the War of Spanish Succession, whose purity as a ground vivid color grew in the textile trade–by the late eighteenth century the East India Company exported over a million pounds of the dyestuff from Bombay and Surat as gild restrictions on its importation eliminated or reduced, as Spanish indigo replaced the Indian origin of Indicum, notwithstanding the plant’s historical toponomastic origins. (Recall the blue dresses worn by Vermeer’s women beneath their linen veils in their private, whose vivid Delft blue made us privileged witnesses of global ties of commerce in quotidian interiors of scrubbed walls.)

The global origins of indigo in the transatlantic trade is aptly tied to a first age of globalization, as much as for elevated reasons of mystical harmony or the spectrum of available paints–whose warmth finds new if dissonantly telling prominence in our ocean maps.

The scarcity of indigo from India was challenged as New World imports reshaped luxury textile markets to feed a growing markets for fashionably vivid colors. But the scarcity of indigo in early modern European markets seems apt to illustrate the shrinking margins of cool waters that are driven by anthropogenic climate change, as global markets for energy prospecting oil and gas fields have released greenhouse gasses es into the atmosphere with seemingly irreversible consequences.

Warmer indigo waters create a slippery if critical band of sea surface temperatures above freezing that has encroached the edges of global arctic oceans–the very region that the scientist James Lovelock, father of climate studies, cunningly chose to be the last remaining temperate region of a climate apocalypse, in The Revenge of Gaia (2006), where the flipping of the global climate due to greenhouse gasses and ended animal life has forced polar migration for its few remaining survivors: those compelled to travel to the only cool sites of the Arctic, migrating to the few remaining oases with camels they have presumably fled where temperatures only cool as the sun’s rays dissipate. If Lovelock’s was a clear-eyed cautionary tale about the stresses on the global system humans created, the equatorial heat already spanning oceans in contemporary maps of eighty and ninety degree water have clear red foci of intensely electric carmine in the Persian Gulf and Gulf of Mexico, and off of China’s coastal waters, that have received less attention than the individual buoys that register “record” heat cresting the magical metric of 100°F. The novelistic retelling of the “Gaia” hypothesis viewing the earth as a coherent organism able to be seen as a self-regulating system in 1972 was dramatically disrupted in ways that offer a bracing story of the consequences of a climate out of balance of which indigo may be an apt indicator indeed.

Melting is something foreign to the waters of the Gulf of Mexico, where we were already breaking significant records in Spring. But we are increasingly relying on new carmines as we used new violets last year to register the extreme heat wave that strained power grids in the west in a previous heat dome in September 2022 that colored the Central Valley, Las Vegas and Phoenix shades of violet as a hot air mass settled over wester states for multiple days. We had warning. We suffered the warmest May on record. per the European Union’s Copernicus Climate Change Service; global sea-surface temperatures hit record highs in May and June, as it became clear that this summer was less of a season than a record of extreme heat.

By early July, a heat dome engulfing southern states around the Gulf of Mexico pushed the color ramp to deep reds, and meant triple digit temperatures of excess heat scary heat dome, whose isotherms span the border, in a reminder if we need it that global disruptions do span borders; El Niño stands to create record global July temperatures, as warm weathers off the global oceans wrap themselves around North America, raising lands temperatures upwards of a hundred degrees Fahrenheit in new record temperature anomalies.

The rising sea surface anomalies suggested extraordinary temperatures of an intensity we’ve rarely experienced, and are challenging our color ramps moving toward darker and darker carmine. The temperatures around the coast of Florida are not limited to the threatened ecosystem of its Keys, where water temperatures above 100F° in late July lead to wide die-offs of coral reefs.

The isotherms tracking landsea temperatures make it hard to get specific or drill down into amidst the array of alarming datapoints. But the deviations of anomalies of sea surface temperatures are a terrifying hint of what might be in store, the Gulf Stream carrying warmer waters than ever to the Arctic North, warming the Baffin and Labrador Seas, as well as parts of Hudson Bay–show lowlands. These regions are already among the fastest warming in the planet–projected to warm at a rate three times higher than the global average, sending fewer cooling winds across Canada and offering less of an amenable subarctic habitat for whales or polar bears.

Sea Surface Temperature Anomaly (Centigrade), June 14, 2023

If June is the month to register the first anomalies of summer months, July has become the time of realizing extreme warming is going off the charts. These temperature records are anomalies we had not imagined, and stretching beyond color ramps with which we are familiar. And they are being circulated with far more alarm than the sense of inescapability already present as the 1980s presented the hottest decade on record–including five of the warmest years since 1890. If the arming of arctic permafrost was first detected in the 1950s–as dozens of exploratory oil wells were drilled in Alaska’s North Slope, the inevitability of global warming was tied to the fears greenhouse gas emissions would bring an exponential growth of CO2 levels in the global atmosphere, forecast to reach the benchmark threshold of a doubling of preindustrial standards by 2030 in the early 1980s, if no reduction of emissions were taken, and the earth entering a path toward irreversible warming of 2 to 5°C by 2020 and a doubling of carbon dioxide levels in the global atmosphere.

If the optimistic hope was to slow warming and carbon doubling until 2060, worries of coastal flooding and erosion–or of land erosion in places like the Gulf of Mexico leading to ocean flooding–the dangers of sea-level rise that is primarily due to fossil fuel combustion–as well as deforestation–has been replaced by even more anxiety-producing stories of the warming of ocean heat and its effects.

The focus of rising sea surface temperatures have striking continental focus in the waters of the Gulf of Mexico–characterized by a surface temperature anomalies from the 1950s, partly due to the low level of the ocean from the seafloor, rising by the mid-1970s and by 1990 at extraordinary rates.

We are hard pressed in the middle of July to realize how sea surface temperatures are poised to escalate with El Nino. But they are so deeply red in places like the Persian Gulf, that global site of oil production, and in the site in our own national waters touted for possible future oil extraction–the Gulf of Mexico. These are among the most anthropogenic areas of the world, made for intense offshore petroleum extraction, where oil seepage and spillage may create a uniquely elevated ability to capture heat in their swirling current coursing in its semi-enclosed ocean waters.

Lilac hues signifying colder global waters are pressed to the Arctic and Antarctic, at the boundaries of or outside the bounds of human settlement. And lilac is a scary reminder that few colder water will be sent southward in the Meridional Overturning Circulation that sends colder, saltier water across global oceans that drives marine upwelling. But if this is the global, the story is in many ways local, too, as the changes in the heat of the Gulf’s surface waters, even before El Niño and La Niña, are warming those gulf waters as astounding rates as they swirl in that semi-enclosed sea-

Climate Reanalyzer, Global Sea Surface Temperatures/July 22, 2023

–and by the end of the month, just four days later, Sea Temperature was introducing lilac in its ramp for global oceans, in an extraordinary expanse, and rightly so, to register the rising ocean temperatures at the equatorial belt as a cause for alarm. Lilac is the only way to communicate these extremes, perhaps, to catch one’s eye, as perhaps Newton knew it would have, as it was feature in any rainbow, but as Newton must have known indigo well from the common use in early modern England of imported indigo dyes–indigo discharge printing of saturated colors long before William Morris prints, in indigo chintz–that were so popular that by 1720 the Calico Act restricted global trade of calicoes and indigo dyes to appease wool gilds who used woad plants, assessing fines for “Use and Warings in Apparel of imported chintz, and also its use or Wear in or about any Bed, Chair, Cushion or other Household furniture”–true indigo gained status to catch or arrest the eye, as indigo or lilac in our maps of current sea surface temperatures. The weaker dye from European woad–the isatin tinctoria of colder climes–was never as vibrant as the imported indigofer tincotria. Before restriction of the luxury import, Newton would have known the treasured dyestuff of “truer” imported indigo: the luxury trade of woad ensured Languedoc’s wealth in 1705 as “the richest in Europe,” but indigo displaced woad’s currency as a guarantor of credit was displaced by indigo, as it displaced the chromatic organization of dyers gilds–red, white, and yellow; green, black, and blue–derived from Aristotelian: indigo’s intensity was implicitly modern in Newton’s rainbow spectrum, unlike blue.

But indigo and lilac haunt the color ramps of sea surface temperatures as extremes, at the arctic edges and the equatorial zones, at the super-hot and indigo waters at the poles formerly freezing “warming hotspots” of the north.

We may have to live with more indigo–just above freezing, where surface water shifts to marine blue–in the rasters of our maps of sea or sea surface temperatures, and try to tell the clearest story possible. This should be a story that is far more explicitly anthropogenic in nature, but a story few maps tell. To do so would be to remind us of the materiality for these changes, and indeed the materiality of Newton’s inclusion of indigo in the rainbow spectra on which our color ramps and buckets rely. The deep reds of those isotherms–whose reds seem so much heavier, impinging itself on the global ocean, no longer bridges land and sea in a topography of heat, given problems of translating land heat to the heat of the surface, force us to contemplate the anthropogenic effects on ocean environments. Whereas Romantic art promised a merging of the human with the natural as an ideal, subsuming the natural to art, the art of mapping anthropogenic influences on nature is central to the intensifying problem of mapping our current relation to our climate emergency.

We might well return to the global synoptic maps of ocean warming, enhanced by appreciation of local detail that are the best ways of gaining access to their meaning and cascading effects. The rapid rise in sea surface temp was not a record, although its surface temperatures had been rapidly rising, but hovered around the 80°F threshold. While the nightly news graphics seek to command attention as an immediate existential threat, however, the deep causes of the surrounding seas’ growing temperatures and the challenge that they pose for oceans’ memory demand greater attention and appreciation for the long-term changes in governance that have gotten us here–the transformation of the Gulf of Mexico to a sort of open bank account of perpetual national oil reserves, able to be claimed by seabed rights, that seep to the ocean, pumping of groundwater to feed crops and cities, phosphorous flows to the coastal ocean and into the sea, deluded by what may well be illusory hopes to inject waste into wells that themselves seep offshore.

The danger signs of red, the sign of danger flags, red alerts, and blood, have been intensifying in the color ramps of overlays that we place on ocean currents in the maps of sea surface temperatures for several years. Yet rather than see the oceans as passive victims of climate change, the maps we make might seek to register or appreciate the active anthropogenic nature of those changes in sites like the Gulf of Mexico and the western and eastern Florida shores. Terrifying climate records had been announced nationwide, of course, by mid-June, before catastrophic rainfall hit New York and Vermont, with accumulated humidity condensing in the air, as anomalies of notable escalation hit the climate community from the first days of June 2023–following the warmest May on record, of a new high by quite a margin, as Antarctic sea ice suddenly shrunk to record lows, setting off alarm bells about global sea surface temperatures that haven’t been able to be silenced.

The outrageous color ramps of astounding rises in sea surface temperatures register a remarkable change in coastal waters, as global oceans hit record highs, with the ocean temperature rising as oceans absorbed the lion’s share of excess anthropogenic energies and a pronounced warming of the North Atlantic Ocean and the Gulf Stream that has sent warming waters to the North Atlantic, in a spectrum of red and blue that suggest the end of the cooling waters of the Arctic Ocean–as well as a global picture of climate change, if we needed one, rooted in the anomaly of sea surface temps across the globe. But as we wonder how those changes will be relate to local government–or how mjuch they outstrip the ability of any local government to respond–the crisis must be seen as one of governmentality, as much as climate.

Dark red and orange map shows Atlantic sea surface heat

In posting the deep lavenders off the chart temperatures that surrounded the coast of Florida this early summer, he Newspaper of Record shifted our attention to the corals, and the danger of their bleaching, beyond indulge in the effects on humans alone of these rising temperatures alone: they weren’t inviting us to take the “animal turn,” but turning attention to how the surprising spectrum was not only about when it was good to swim, but concretized the warming as a living record of marine health, akin to a charismatic keystone species. The warming is rarely tied explicitly to government, but an early engraved map of Florida might hint at the difficulty of mapping clear boundaries of land and sea–a Google maps artifact, but also one of mapping softwares–not because of its greater accuracies or inaccuracies, but the complex relations between land and sea that are suggested around the Gulf of Florida, both in the land-sea fracturing that defined the ‘state’ and its government, and the dotted lines of those far less sharply defined shores.

As K. brevis sends unprecedentedly ballooning neurotoxins s into the Gulf of Mexico and to Florida’s Gulf Coast waters, yet again, and blows onshore to trigger lung symptoms for many, as it enters the air, we are reminded of how much land and sea are tied, in the rusty red tide lasting for months off of Florida’s western coast washes a shore, we might ask about the porous nature of good government in Florida, both East and West alike, by looking at the appreciation of this porous boundary of the shore that was central to early maps of the region–not only before landfill led to the remaking of the state, but before we were convinced of a firm separation of land and sea.

Sailors of course paid more attention not only to the existance of islands in the Gulf of Mexico, where their crafts would run ashore, but to the great sand banks as the Great Bank of the Bahama (or Great Bahama Bank) that is one of the largest of the world’s fringing reefs, even in an era of routine sand pillaging and illegal sand mining. But as our shores have become too narrowly defined, as we have viewed them as the edges of government. As we imagine the shores overly sharply defined, the irony may be, unregulated drainage of sewage, industrial fertilizer, and urban wastewater create decisively warming temps around that quite critical coastal margin, where warming temperatures enter into that purple, reminding us yet again, in way, howe much anthropogenically caused heat oceans are trying to absorb–and how off the charts the rises in temperatures are to the ocean’s memory. The presence of and threatens to ocean memory might well be part of the stories that we tell about climate change, and indeed made central to them.

Indeed, rather than see the ocean as a glassy surface, as if the surface temperature were a record of the sea surface, suspended by an illusion of calm waters, we need maps that allow us to look deeper in maps, to the areas underneath, as this post has tried, and noting what else is on the surface of the seas as they circulate ever-warmer waters off sensitive coastal environments. So much is suggested by the coral reefs, dotted zones in danger of being bleached at higher temperatures. Rebecca Solnit invites we entertain the climate crisis as “in part a storytelling crisis,” a crisis in which we find ourselves “hemmed in by stories that prevent us from seeing, or believing in, or acting on the possibilities for change.” The foreclosure of possibilities are perhaps nowhere as evident in the finality of the color ramps of maps of global climate that trigger our alarm; color ramps of sea surface temperatures are, in their opacities, perhaps as much as fault as being part of that problem. They are an ultimatum, as much as any thing like a narrative, as much as a late-arriving warning sign and a cry for help: the stark disequilibria of something so large as a global climate or “surface temperature” is hard to grasp with anything like traction, let alone weave a story around.

Yet the problem of mapping a story of where we are requires more depth, and detail, of appreciation and perhaps wonder, as much as fear. As much as posing existential issues of impending ruptures in ocean habitat and even in ocean memory, we might pay better attention to the local scales of what is lost. For the inattention to the changes that are already quite evident in the membranes of coasts and the margins of shores, stories that don’t leave us much room to move. They are multiply depressing stories about about politics, or governance, and the irresponsible expansion of seabed governance to mine and extract non-renewable energy sources as petroleum and natural gas, to supply petrochemical needs. Yet the stories that we tell are perhaps so depressing as they ignore and are rarely addressing shores as lived environments or enduring habitat but the steep fears and constraints of coastal risk and of both urgency and emergency.

We are perhaps far, far beyond investigation, regulation, rehabilitation, or clean up of isolated sites contaminated by the spills and discharges. But we must look deeper into the maps, perhaps beneath the frustrating opacities of crimson and the misleadingly gentle lavender. Hui Shi of the Farallon Institute in Petaluma, CA suggests that similarity in ocean surface temperature from one year to the next is the best “simple metric for ocean memory,” independently from atmosphere-ocean exchanges, as a systemic change in ecological memory. Another way to see this, of course, is by remembering the long permeable membrane of Florida shores, an implicit part of its good government, and one that has been neglected in the erasure of banks, reefs, and undersea health that is long part of the region, and erased by the reduction of the region’s “government” to the policies of one state–and to call more attention to the role of good government in the very porous relation of land and sea in Florida’s government, that appreciates the state’s integral connection to the Gulf of Mexico as well as the “Gulf of Florida” and Atlantic Ocean.

We map the sea-surface temperatures around Florida by a color ramp, as if they were similar or about the same as land temperatures. they are not. Not only does the ocean absorb a huge amount of anthropogenically driven climate change. The disruptive nature of marine heat-waves are less similar to those on land, as they can be more intense, and more sudden, and even more directly impacting human health and disrupting abilities of meteorological assessment and prediction, and compromising our relation to the shores. If ocean warming accounts for some 63% of the stored heat of the planet, rising temperatures of expanding oceans threaten coastal communities, and undermine the very clear lines we drawn in most of our maps–including weather maps–that fix edges between land and sea as distinct divides. They are not, and this is a casualty, perhaps, of the graphic syntax of the map, which signals a divide, rather than a membrane or, better yet, medium.

The oceanic amnesia between rapid sea-surface temperature changes can be mapped, scientists have argued, in a neat cognate of a sea-surface temperature map, in terms of increasing amnesia–a sort of memory-decline on a global scale–that is jarring because of the choice of blue as a metric of declining memory, and a decline in the continuity between temperatures between one day and the other, that is not only in the water of the ocean, but also its habitat and ecological stability and vitality–the very problem of the coral reefs that are the focus of the Times article. The discontinuities of sea-surface temperatures suggest a major disrupter, in other words, tied to different scenarios of climate emissions, reflecting decreased thermal inertia of the uppermost layer of the ocean, as it grows shallower in response to anthropogenic warming.

 She, et al., Science Advances (2022) 

She’s metric for “ocean memory” is perhaps a far better and significant chart than the existential immediate sea surface temps, and demands to be placed in a sense of temporal duration, tied to the degree of ocean memory that seems to have existed in the last century, and over different possible emissions scenarios, for the coming decades. He suggests a need for attention to the management of marine ecosystems–which we regard in a largely quite laissez-faire manner–and expansion of government from land-based regions to oceanic environments, and to those sensitive margins of land and sea–watersheds, swamps, tide pools, shores–where life is increasingly abundant, but are also increasingly determinant of biotic and environmental health, in ways that makes them health multipliers. If clever folk at the island-centric UH Mānoa have documented the increased ocean heat anomalies from 1993 to 2019 in the upper layers of oceans, those very sensitive registers of ocean memory, of seven hundred meters in depth, the warming of 53% of global oceans suggests a decline in memory, of some significance, with but 3% of global oceans able to be characterized by cooling trends. From 1968 to 2019, whereas ocean warming was found in 72-9% of global oceans, cooling confined to but 1-2%, in a terrifying trend that only mirrors the dangers of the scale of such a massive memory loss.

chart

If speculative in nature, the historical depth of a discussion of long-term ocean memory suggests something quite distinct from the structural sort of histoire immobile as is fitting the ocean sea: rather than rooted in economic arrangements that we can map by structures, the slipping away of ocean memory suggests a receding shoreline, or a failed ability to grasp the sudden changes of weather that increasingly characterizes the sea, an erosion, in other words, of a measure critical to ocean health not rooted in the day-to-day nature of surface temperatures, or the disputed averages of temperature over time, but of the ability to navigate the coming sharp changes in ocean health, which, with a majority of humans living on or near the shores, we should be compelled to attend. We risk, as my late friend John Gillis reminded us often in his final years, “turning our back on the shore,” imagining the healh of the oceans to exist independnetly of the land, and the ocean able to be mapped as an extension of the topography and heat of the land.

Another way of seeing this absence of continuity of temperatures might be in terms of the setting tight the oceans offer: the predictability of the warmers as hospitable environments, in other words, rather than as sites of escalating temperatures approaching trigger points for the massive die-offs we have seen. To be sure, surface temperatures are not only reason for die-offs. But they are at play in them, and probably more than we realize: the failure of oceanic environments to be hospitable environments are not only able to be measured by individual digits of Centigrade and Fahrenheit, but, as oceans are absorbing ever greater surface temperatures, of ecosystems most affected by solar irradiation, the rise of sea surface temperatures in the Gulf of Mexico between 1970 and 2020 stands out–warming at twice the rate of the upper layer of global oceans, as ocean heat content in the region has risen so dramatically to raise questions about environmental ocean management–and to explore reasons for the imbalances in Ocean Heat Content (OHT) globally in relation to anthropogenic activity in the upper 700 meters of the ocean, that can help track marine heatwaves that have become greatly more prevalent in the past century.

And the Gulf of Mexico–which receives runoff from over a hundred and fifty rivers from thirty-one out of fifty states, is a sort of distillation of the polluted content of our American rives, in ways that riverwater from more than 150 rivers and runoff from 31 of the 50 states, including nitrogen and phosphates, as well as offshore petroleum-producing zones, a main cause for hypoxic zones and harmful algal blooms, is notably warming at twice the rate of the world’s oceans.

If coastal Florida had seen a distinct rise of temperatures in the heat content of offshore waters, a huge stress on marine environments, in the 1990s and early twentieth century, the recent escalation of heat waves across the Atlantic and Gulf Stream suggest a real reason for panic, tied to displacing habitat, and less salty–and less dense–ocean waters, that are especially dangerous to the vitality of oceanic environments–and the danger of die-offs, often not mapped by digits alone. Far better to focus on and scrutinize trends, disturbances, and abrupt shocks to the ocean’s environment, and to the mitigation of those shocks issuing from the land, and interface of land and sea, where toxins and industrial discharge and pesticide runoff leaches offshore freely. Even a relatively circumscribed “deep view” of warming trends from, as it happens, the start of the Trump era, reminds us, by its dark red blotches, of the warming waters off of American coasts, warmed by the Gulf Stream that carried Caribbean waters from the Gulf of Mexico along the eastern seaboard.

Floating Sargasso Sea

When we see the edges of our world as blue, we do so from an anthropocentric perspective. The pale blue line of the horizon is a product of atmospheric distortion, but is an artifact created from a line of sight. If the horizon privileged as the position of the observer, the construction of clear edges might be questioned by the presence of the prolific Sargassum bloom that stretches across the Atlantic Ocean, bridging continents that reflects the abundance of nitrogen in ocean environments. The floating macroalgae seems to disrupt the idea of a fixed perspective on the sea, and the very construction of clear edges questioned by its presence. For the approach of this brown biomass that now bridges continents antiquates the idea of having one single, fixed perspective on the sea. But while we see the mass of seaweed as an invasion of territorial waters, a problem of coastal management, whose migration outside the ocean currents that bound the Sargasso Sea that spread across the South Atlantic, unlike the constant temperatures of the North Atlantic, the influx of macroaglal migration of this Sargassum seems the detritus not only of ocean warming on a global stage.

ARABIAN SARGASSO NEW SARGASSUM INVASIVE SPECIES BLOOMS WORLD PLAGUES THEORY  THEORETICAL STUDIES THESIS SEAS SEAWEED MIGRATIONS FROM ATLANTIC TO  EQUATORIAL INDIAN AND PACIFIC OCEANS

We are unsure of the relation to the growing brown-yellow biomass to our national waters, or the lines we draw around them, but are preoccupied that it is entering them. We might ask, however, why we are mapping the sargassum in remote sensing, we are projecting its origin beyond our own lands, and the scale at which we are depositing nitrogen-rich effluent into coastal waters at a terrifyingly high rate. The entry of plumes of nitrogen in the ocean is not defined by a fixed line. Indeed, the fixity of the ocean’s horizon might be a relic of the navigators of a more open ocean of the past. John Updike once parsed the maritime horizon that crisply divided the blue sky from the sea as a border between two worlds–

That line is the horizon line,

The blue above it is divine.

The blue below it is marine,

Sometimes the blue below is green.

–in rhyming couplets whose elegance echoed a divide that seemed quite fixed. Updike has described himself as attending as a graphic artist to blank blue skies, or snowy surfaces, or ocean surfaces, “tracing what I see with a mental finger or pen” while meditating on the limits of his field of vision. Crisp lines and fixed divisions are upset by the appearance of sargassum on the global stage, a blurred brown streak of a mobility that disrupts our categories of state lines and land-locked territoriality. But its appearance is also born of it. If Updike drew clear dividing lines of an almost early modern character in the romantic consciousness of a bored yachtsman off the New England coast, the drawing of crisp dividing lines in our ocean maps is disrupted by the exponential growth of a large biomass of sargasso about to make landfall along Central American shores. The increased coastal anxieties of the exponential growth in of macroalgae seems far away from the New England coast–however much algal blooms and sea-level rise, as well as erosion, threaten the Maine coast–but we might do well to start by mapping the sargassum of the South Atlantic from the perspective of the seaweed, as much a from the shores.

The rise of sargassum approaching the shores of the Caribbean may demand the reaction of national waters, but are in no small part the fruit of ocean pollutants and phosphorus effluents that are offering nutrients to the algae on unprecedented scale. Indeed the growing application of fertilizer to meet “local” demands of the production of food, from West Africa to the Amazon, suggest that the growth of this new abundant flotilla of Sargassum is a product of global trade–as much, perhaps, as the flow of migrants a respond to sharpening economic inequality, that demands to be mapped as such.  If the hopes to harvest macroalgae on ocean waters encouraged oceanic clean-up operations as SeaVax to direct ambitions from industrial waste and oil spills to harvest the macro-algae by giant oceanic cleanup operation, in plans for the SeaVax-Sargasso™ or AmphiMax-Sargasso™ to meet the growing blooms of brown seaweed on the high seas from becoming a coastal threat, the aim to prevent the large brown seaweed from approaching national waters hints at how intertwined its biomass is with global economic exchange that this post tries to develop and expand upon.

Atlantic Sargassum, 2023 and Exclusive Economic Zones in Caribbean Waters

As we map the flotilla Sargassum approaching Caribbean shores as a threat to “coastal waters” as it enters countries’ “Exclusive Economic Zone” and “national waters”, we remove the prolific seaweed’s unprecedented abundance from growing increased food from the lands by emending lands with fertilizer, rather than ocean warming. If entrepreneurial operations as SeaVax-Sargasso™ or AmphiMax-Sargasso™ oriented local businesses and governments to the surface of oceans, the global risks of nitrogen plumes in river run-off must be mapped far more deeply than the above satellite map of millions of metric tons of sargassum biomass, more often cast in terms of seasonal migration rather than the engineering of coastal waters.

The absence of clear lines in the Atlantic ocean, where the migration of macroalgae floats across high ocean waters, seems a canary in the coal mine of a warming world. One might see its sudden appearance as the result not of anthropogenic climate change, but an alien monster of global industry. Amidst 269,000 tons of plastic refuse floating on the undulating surface of global oceans, the thirteen tons of biomass floating in the mid-Atlantic may seem slight, but the astounding prolific growth of brown strings of algae in the Atlantic are an oceanic anomaly, moving shoreward, distant from the Sargasso Sea in Sargassum that long sequestered similar strands of seaweed in the mid-Atlantic amidst ocean currents.

Unlike the vitality long tied to the Sargasso Sea–first, a sea of monsters, but then a sea of untold fertility, a disproportionate producer of oxygen and carbon sink akin to a floating rainforest–the expansion of sargassum species has become a deep danger for our coasts and shores. It is as if spun off of the wild vitality of the Sargasso Sea, long an image of terror–the “Sea of Grassy Death,” for Mickey Spillane, littered with lost ships as a “living graveyard,” or “mystical ocean graveyard, hundreds of miles wide, hundreds of fathoms deep”–no longer constrained by ocean currents conjures cascading threats to coastal management in an age of climate change that knows no edges, not because of what lies hidden in its fearful deep–but what sort of algal monsters are approaching the white sands of our vacation shores.

The strands of floating Sargassum were reinterpreted in the ecology movement, due to Rachel Carson’s classic work, as a site that nourished the abundant growth of microorganisms, a feeding grounds for fish and a floating rain forest of intense vitality: but the prolific floating Sargassum that now appears to extend across the Atlantic below the equatorial current is mapped as unwanted migrants, destined to foul the shores and coastal habitats across the Caribbean; the long strands of algal mats drifting on the ocean’s surface loom as the latest global casualty of climate change.

Charles Darwin, abord the HMS Beagle visiting ports on the Atlantic, took seaweed as a critical register of globalism. As he docked at ports in South America, Darwin gathered samples of algae that he collected samples, catalogued for his perusal what he perceived as a register of oceanic life and vitality, in ways that influence Ernst Haeckle and others: he sent weeds to correspondents from the Falklands and elsewhere as keys to the similar if unique habitats that evolved in benthic waters, impressed by the brown-green marcoralgae forests waving at him at the Galapagos, as if blossoming in the shallow, nutrient-rich waters of near coastal environments. The seaweeds were a basic register of biologic of global diversity studies on his travels, able to be sent on letters for future study–

Amphiroa orbignyana, coralline red algae

–and of the primitive forms of life that evolved in the near shore rocks, evidence of the biodiversity of Atlantic waters and their vitality. But if Darwin collected Patagonian and other algae with care, the prolific biomass of floating kelp steaming toward Caribbean beaches out of control. Their extraordinary plenty in rafts of foot-long seaweeds are carried by currents destined as they wash ashore to kill coastal habitat and environments.

The abundance of the floating Sargassum, like a return of the repressed, removed from holists in coastal environments, again haunts the oceanic waters in an age of global warming in a monstrous manner, returning to prominence as an anomaly we are unable to catalogue or fit into our maps of ocean waters. Floating in international waters, the macroalgae appear removed from national jurisdiction, but is hardly “natural” in appearance. It has begun to mass over the Atlantic High Seas in recent decades, poised to redraw the margins of our coasts. The growth of inordinate algal biomass of algal strands are poised to swamp the divide between land and sea, as if a liberalization of the greenhouse effect, redrawing the margins of shores and land-sea divide. The growth of such an unprecedented mass of Sargassum, far from the confining currents that bound the Sargasso Sea, have been located across the high seas of the mid-Atlantic, but demand to be studied in relation to how nitrogen is entering our coastal oceans, shifting the ratio of phosphorous and nitrogen in the marine bath in which they float, as much as they deriving warming oceanic temperatures. The man-made nature of the anthropogenic changes in large coastal rivers–the Amazon or the Niger River basin, the Volta, and Mississippi–send greater blooms of nitrogen discharge in the Atlantic, shifting the chemical composition of coastal waters in unprecedented ways.

The blue marine is no longer only sometimes green, but often brown with algae. The blue marine is no longer only sometimes green. Covered with algal bloom, it is red, green, or often brown. As many coastal and lake waters gain industrial hues, unprecedentedly saturated with indelible hues of algal blooms, the rise of the Great Atlantic Sargassum Belt in recent years has become the latest evidence of the massive scale or cascading of climate change. We might imagine the bloom, given that it is viewable from space, as a surface mark akin to the storm of the Great Red Spot of Jupiter, but the abundant growth of seaweed, maps as a global disruption, evidence of how much “nature” no longer exists as a category. But if the Giant Red Spot is in fact a huge storm, a vortex swirling for centuries as a supersized cyclone–the largest storm in the solar system, enduring for centuries, far deeper than it appears from the gaseous surface–the undercurrents of the sargassum bloom are elided by remote sensing provides. Oceanographers distinguish ocean bathymetry as holding littoral, pelagic, and abyssal species, the shoreline clustering of seaweeds on rocky coasts are unlike the pelagic algae that seems a new seasonal visitor to our shores.

Coastal and Ocean Distribution of Brown Algae, 2020/published by Global Biodiversity Information Foundation

Anthropogenic influences on ocean waters demand unpacking the remove of an anthropocentric point of view Algal blooms–the massive efflorescence of Sargassum in the Caribbean, offering reminders (as if we needed them) of just how poorly adapted are mental constructs to understand the state of oceans. There may be some historical circularity in the fear with which the impending arrival of thirteen tons of Sargassum on the shores of the Americas and Caribbean islands is described: as the early modern sailors who were terrified of the Sargasso Sea as a point of disorientation, concealing monsters, we are terrified at the accumulation of brown coastal seaweed–macroalgae that floats in large masses, accumulating in the Gulf of Mexico and tropical Atlantic, in a dramatic deviation from the largely coastal settlement of seaweed across the globe. If the Sargasso Sea is as big as America, the belt of Sargassum spread across the Atlantic is as large or larger, if more dispersed.

Unlike the global distribution of brown seaweed on our coasts, the flotilla of brown sargasso whose density has caused such alarm is anything but natural in its copious abundance. The superbloom of brown macroaglal biomass that seems born by winds into the Caribbean is indeed a cause for alarm. The excessive abundance of this algae is a hyper-event, the latest evidence of the anthropogenic alteration of ocean waters, not directly driven by ocean warming, but the new nature of oceans. The increasing abundance of macroalgae were perhaps dislodged form the Sargasso Sea by the southern-shifted winds, where Sargassum were long confined by currents in the mid-Atlantic; the extravagant growth in global waters however, demands to be mapped. The feared arrival of the biomass that threatens to clot coastlines, basins, estuaries, and inlets this summer is the largest harmful algal bloom on earth. Yet our maps may not capture ho much it is the result of altered by human activity. We do not pause to analyze its appearance, or try to map it, as an anthropogenic effect, viewing the remotely sensed maps of its biomass floating toward our shores as if they migrated from afar, distancing the macroalgae on the high seas from any anthropogenic in origin.

The unprecedented offshore growth of a seaweed that offers precious habitat to life has accelerated in growth in recent years. The seasonal arrival of anthropogenically induced fertilizer has changed the relation of not only land to ocean, but ocean ecology, accelerated by increased rainstorms driving more plumes of nitrogen to ocean waters, including unknown amounts of deforestation-induced runoff excess sediment whose influence on coastal ecology demands to be better mapped.

The arrival of the thirteen tons of floating biomass into the coastal waters of the Americas is a cause for alarm–described as an “invasion” and “creeping threat.” Species of Sargassum have been arriving in Caribbean waters since 2015 in large quantities to pose a threat to coastal ecosystems as well as shoreline management. Large strings of algae of at least two species–and several varieties–have spread beyond the current-bound Sargasso Sea, floating on ocean currents across the Atlantic growing by vegetative growth, perhaps accelerated by warming waters, born by winds in ways that have echoed the cataclysmic metaphors we have been accustomed to describe migration. The appearance of what is cast as a problem of coastal management is newly prominent in global oceans as a problem of climate change: even if Sargassum are ecosystems with long historical roots, the exponential growth in floating seaweed has led to search for metaphors of a climate emergency and alarm bell of an anomalous growth of brown biomass, compromising the Caribbean beaches of countries where summer tourism is such a vital part of the economy.

Yet the exponential growth of Sargassum is perhaps better mapped as yet another fracture in the illusion of prosperity that drives globalization; evidence of the disturbances in the coastal biome of offshore life that has been triggered by the release of plumes of nitrogen from expanding application of fertilizer, from Mexico to Brazil to West Africa, whose discharge into the coastal ocean have set the stage for such a prolific algal super-bloom? We are overly comfortable, perhaps, mapping the “arrival” of the large biomass of kelp from remote satellite sensing, placing the bloom outside of our national waters, and the geographic space of a nation-state. We map the arrival of the astounding macroalgal mass that stretches across the Atlantic measured by remote sensing to grasp its density, by metaphors of migration of brown-skinned kelp as if they were “foreign” to our coastal ecosystem, possessed by economic fears, we adopt a perspective primarily from the coast, or an anthropocentric cartography, driven by feared economic vulnerability by which we map migration more generally, and in which migration often seems increasingly embedded. Perhaps it would be of help to map the arrival from a new sort of “story-map,” however, more tied to globalism and economic engines of globalization, from the perspective of the Sargassum itself.

Fearful of the anomalous expansion of macroalgal biomass that is floating across the Atlantic, heading toward our national waters, we map the arrival of the Great Atlantic Sargasso Belt by cartographic fictions of ‘Exclusive’ Economic Zones (EEZ’s), as if the ocean were a flat space, exploiting the fictional nature of maps to remain in our comfort zones. As much as the solace that was found in the sea, we are frustrated at the absent geometry to orient us to the seaweed floating in the Caribbean about to approach the web of islands at the edge of the open sea. The dark green surroundings of earlier eighteenth-century nautical routes magnified the equatorial islands of the Caribbean that were sources of economic wealth, as if seaweed clung to their coasts, before breaking off to join the dense fields of weeds that were estimated to b about 10 million tons by A. E. Parr to be circulating at the heart of the Atlantic, where Columbus first described seeing as dawn rose, on his first return from America, as being surrounded by “so much grass that it seemed to be the sea curdled with it, and it came from the West [en amaneciendo hallaron tanta yerba que parecía ser la mar cuajada de ella, y venía del Oeste” (Viernes 21 septiembre 1492)” on Friday, September 21, 1492.

If the “Relaciones y Cartas” that Columbus kept from his trip preserve a primal record of contact with the drifting, fragmenting, asexually reproducing, vital region of the Sargasso Sea, whose macro-alga only die if they are picked up by outward flowing currents from its permeable edges, the maps made for Columbus’ voyage were famously made to capture that the earth was not flat. And yet, we pretend the ocean is flat, and with clear edges, we fail to map the changed oceans in an era of climate change, whose cascading effects extend far beyond rising ocean temperatures. As much as it makes sense to see the seaweed blooms as result of rising temperatures, in an era of anthropogenic change. As coastal waters are increasingly defined by discharge of rivers of fertilizer feeding the Gulf of Mexico and the estuary of the Amazon, the river that feeds more freshwater to the ocean than any other, its sediment increasingly filled with phosphorous from its many sediment-laden tributaries, providing a nourishing bath for the Sargassum. The increased flux of phosphorus to the ocean has grown as Amazonia is clearcut, replaced by farmlands, and as increasing flooding from extreme weather, and cyclonic activity, washes organic matter to the ocean, to be released in its coastal ocean, that have long raised question of the phosphorous cycle.

The discharge of rivers that defined the Atlantic reveal the need for new tools of understanding the shift in phosphorus in the Atlantic in an age of globalization. The flux of phosphorous may help to track the explosive growth in the mid-Atlantic of sargassum, whose tangled strands have grown a hundred-fold since 2011, when they first appeared, to the south of the Sargasso Sea where it was long contained by equatorial currents. The irregular expanse of seaweed–thirteen tons of macroalgal biomass, we have no idea how to deposit or dispose, even in an era when Florida produced four times as much solid waste annually, and twenty times as much floating garbage lie in our oceans. In an era when plastic waste annually accumulates in ocean gyres, the stream of living seaweed has become, paradoxically, the latest cause for alarm, an unexpected anthropogenic substrate for bacteria, upsetting existing horizons for the gyres already accumulating in extensive pools of plastic waste across the North Atlantic, filling the seas with floating plastic debris, not to mention the microfibers that fill the deep sea–overlapping if not centered at the Sargasso Sea.

Can we better map the seasonal arrival of sargassum that is now again approaching our coasts in the midst of these changing seas? For those early modern Atlantic sailors, the region of the Sargasso Sea know no clear bounds–even as the early modern ties to South America were defined by creating clear meridians whose bearings were located in London, Paris, or, famously, the Cape Verde islands in the Treaty of Tordesillas. As the mass of tangled seaweed was feared to hide terrifying shoals and monsters, named after the Spanish word for kelp–sargazo–that swished again the prows of caravels, they realized this floating biomass was a new wilderness, sensing its brown-green surface concealed monsters or dangerous shoals against which they might be stranded, feared the Sargasso Sea as a foreign floating mass. Although the euphonious sound of this new marine oceanic body, later re-imagined a site of adventure or final frontier of wilderness by the early twentieth century–when many sailors continued to avoid the floating biomass–the arrival of the new variety of sargassum that is accumulating in long strands we are calling a Belt poses new fears for the modern nation-state since it appeared with surprising prominence in July, 2018–but has dramatically expanded by 2023. While we map the biomass from the perspective of shores, and from the fears it poses to coastal environments, the accumulation of seaweed seems closely tied to the displacement of phosphorous that heavy rainfall events increase by a factor of two- to four-fold. As anthropogenic inputs–and increased nitrogen fertilizer–stand to double phosphate flux to the coastal ocean, further accelerated by multipliers in an age of extreme weather, its entry acts as a biological pump, shifting the ambient waters for which it provides a nursery–

A Massive Seaweed Bloom in the Atlantic

–which a story or narrative of migration seems hardly able to capture. The complex problem of causation driven primarily by ocean circulation and rainfall threatens to remove the human agency at the origin of the massive macroalgal superbloom across the ocean, driven by a change in the ocean waters that the Sargassum species has long lived, but has become prolific across the Caribbean and Central Atlantic, rather than being confined within the rich habitat of the Sargassum Sea. If the delicate ecosystems that floating beds of Sargassum has created in the shoreless “Sargassum Sea” has been protected in international waters, and the contribution of the sea as a massive carbon sink in proportion to global oceans has led it to be called a “floating rainforest,” the robust growth of the pelagic algae demands increasing global attention–if its “migrations” are poorly understood only in reference to ocean shores. The astoundingly prolific volume of Central Atlantic Sargassum has boomed in a manner we cannot only understand by narratives of migration.

The clots of floating marine seaweed in the news–the Great Atlantic Sargassum Belt–is running across edges in troubling ways. The pelagic seaweed is suggestive of an upwelling of nutrients off West Africa, but seems arrival of blooms both off the coast of Africa and at the mouth of the Amazon suggest a new anomaly in the ocean, driven by the ocean circulation, unlike the binding of the Sargasso Sea by ocean currents. The GASB, stretching across the Atlantic from West Africa to the Gulf of Mexico, is an icon of globalism, one that demands mapping not only as an oceanic phenomenon, however, but a disturbance that seems deeply tied to the illusion of affluence that investment in fertilizer and the application of fertilizer to lands from Africa to South America, in an attempt to boost the agrarian self-sufficiency across the global South.

In contemplating the fixed line of the horizon, Updike, perhaps without ever intending, evokes the eschatology early modern transatlantic voyagers shared navigating high seas by dead reckoning and astrological bearings while they trusted to the divine. If early modern sailors were deeply disoriented by encountering the mid-Atlantic mass of swirling seaweed they knew as the Sargasso Sea–after the tawny tangles of floating kelp that swirl in its transparent waters, using the Spanish for ‘kelp’–saragazo–to describe the separate sea colored brown and gold, that was clearly a place apart, in Rachel Carson’s memorable phrase, “forgotten by the winds, deserted by the strong flow of waters that girdle it as with a river.. Trying to map the seaweed rainforest in their terms, long feared the dangers of hidden shoals or monsters, avoided by early sailors, and mariners through the nineteenth century, has long posed challenges because of its lack of edges. The half-rhymes of John Updike’s couplets of pentameter conceal a deep truth, but also also perpetuate a half-truth of marine edges, more than a deep truth of life at sea. If Carson believed that strands of seaweed were transported from the West Indies’ shores by hurricanes, carried up by the Gulf Stream, carrying marine creatures from coastal banks to the “new world” of the mid-Atlantic ocean, the size alone of the Great Atlantic Sargassum Belt–GASB–is a New World of unclear edges, registered by a dedicated Satellite-Based Sargassum Watch System that registered the wind-driven approach of floating Sargassum, whose greater density as they move westward qualify metaphors of migration.

2023

The anomalous size of seaweed strands in the Sargassum Belt are not bound by any edges. Unlike Updike’s horizon, the floating fields of macroalgae brook little boredom in their undulating expanse. As it approaches our shores, nourished not by warming seas–as often imagined–it appears fed by weather of global warming have triggered discharge of more nitrogen in major rivers from Africa to South America, as flooding and torrential rains and extreme weather have channeled more nitrogen fertilizer than ever intended into the Atlantic waters. The anomalous size of seaweed distorts any clearly defined a line of sight. Indeed, if the ocean hardly prepared sailors for encountering the tawny tangles of kelp floating in transparent Caribbean waters in the Sargasso Sea, the surprise and astonishment of the appearance of sargassum that has grown is even greater. The extraordinary hundred-fold multiplication of sargassum that has since 2010 been clotting Caribbean coasts demands mapping not on two dimensions, as it is normally visualized, based on NASA’s satellite maps, but in the ocean’s changing character and indeed chemical composition, as floating and nurtured in an increasingly nitrogen-rich bath.

1. If the floating sargassum we track on the ocean surface does not seem a direct result of ocean warming, an anomaly of climate change, it is the fruit of extreme storms that have washed copious amounts of nitrogen-rich fertilizer that flows from our rivers, far from the agrarian soils they were intended to emend; we hardly track the entrance of nitrogen into the coastal waters of our oceans, beyond the continental shelf, but the new variety of sargassum clotting the coasts of Caribbean waters hold far greater nitrogen than the sargassum weeds floating to the north in the expanse of the Sargasso Sea, stretching from the Bahamas to the Canary Islands. If late nineteenth-century cartographers who perhaps mapped with greater surety than later generations fell back on nervously quivering lines to map, already realizing, it was indeed “a world apart” lying outside conventions of terrestrial or marine mapping.

The tawny gold biomass swirling mid-ocean in the Sargasso Sea is not mapped by clear edges or blue edges: in 1875, cartographers rendered the long trails of sargassum seaweed that provide the Sea its euphonious name by quivering lines, between the North Equatorial Current and the Gulf Stream, two currents that set itself off apart from the mapped expanse as a region apart, perhaps suggesting the rich marine habitat it provided for fish, birds, and pacific pelagics, over a century before laws of ecological protections prevented marine trawling or harvesting of the sargassum in the region. Some of the plants circulating in the sea less defined by currents may have belonged to the gold-brown fields of sargassum that swished the prows of the caravels as Columbus returned to Spain, still circulating afloat in a region girdled by ocean currents–the prows of the boats broke flotillas of floating algae that “appeared suddenly floating a lot of herbs [Apareceiron parcels yerba mocha]” , Columbus wrote in a letter of 1493, far from the shores, soon described as its own sea. If the Sargassum Columbus encountered was feared, an d the fields of the Sargasso Sea avoided lest they entrap the sailing vessels or conceal monsters of a deep that may well have fed there, animated by the mirages of shipwrecked vessels condemned to rotate slowly in listless waters, as the ArcGIS story map “The Saga of Sargassum” suggests, after about 1500, we lack maps to chart the fear of Sargassum in an anthropgenic ocean pollution, we might start by better examining mapping the Sargassum we plot by remote sensing in relation engines of anthropogenic change–lest we allow the “layers” of ArcGIS to remap the ocean’s surface as if it were flat or had clear territorial edges.

Shifting Routes that Columbus Took in his Four Transatlantic Voyages in Relation to the Feared Sargsasso Sea

The mats of floating sargassum we map as arriving to our shores appears a different species than the sea, lying to its south, as a massive algal bloom. The Atlantic Sargassum Belt suggests its own parallel global reach. It colors the near offshore, without by fixed edges, but demands a new story map of sorts. In an age marked by anthropogenic change, our shores are blurred by red tides, blue-green macroalgae, and phosphorous-fed cyan-toxins that generated increased health advisories. As coastal waters across the United States are increasingly mapped by river-born fertilizer, we might well examine the appearance of an unprecedented on the open seas–over twenty million tons of floating sargassum, a blue-green algae, poised to clog shores and pose a real health risk, as fed and nourished by the increasing nitrogen concentrations in the largest rivers’ coastal plumes. To map the sargassum that has begun to fill the Caribbean since 2011, we would do well to explore narrative models beyond that of migration, all too often coded for immigration in national waters, charting the sudden appearance of the mass of macroalgae in the mid-Atlantic.

These are stories not only of living plants torn from their holdfasts in the coastal waters of the West Indies, ripped into the ocean by hurricanes to enter the northern border of the swirling Sargassso Sea, the metaphors of Rachel Carson, who so carefully oriented us to the ocean and the sea as an inadequately mapped area of vitality and life. If the power of her model of writing about the sea provided powerful precedent for how Jean Rhys finished later an alternative version of the literary classic Jane Eyre, of how Rochester’s first wife, Bertha, arrived in England, stripped of her West Indian name, Antoinette, after being torn from the island of Jamaica by Rochester, who took her properties and house as his possession, in a painful act of appropriation, and patriarchal authority, before he married Jane Eyre, embedded in a landscape of poqt-colonialization as much as the English manor. Rochester is described by Rhys as unable to orient himself to Antoinette’s land and life, disoriented and stunned before the blue-green sea of the island on which he never gained his sense of bearings–“‘Everything is too much. . . . Too much blue, too much purple, too much green.” His return to England from Jamaica with his new wife clearly mirrored the painful reverse path of a transatlantic slave trade that formed Jamaican plantations and properties, a model of extractive economies of the islands Rhys used, with the model of the oceanic circulation, as the absent backstory for the woman known only as the “madwoman in the attic,” as a story of colonization and expropriation, that needs to be better integrated into our mapping of the appearance of offshore imbalances that may have encouraged the sargassum superbloom. Antoinette half-conjured from a printed map, “England, rosy pink in the geography book map, but on the page opposite the words were closely crowded, heavy looking. Exports, coal, iron wool. Then Imports and Character of Inhabitants,” trying to grasp the global narrative of the extraction of sugar from plantations enriched men like Rochester to the islands, and its wealth. (Antoinette barely imagines a place “filled with fields of corn like sugar-cane fields, but gold colour and not so tall,” as if trying to ken the global wheels of economy that lead Rochester to so value her estate, and, upon arriving in Rochester’s house, fears she was in fact never brought to this place England, convinced “we lost our way to England” while at sea, as we “changed course and lost our way to England, and that “this cardboard house where I walk at night is not England.”

The narrative of economic extraction of sugar cane and agrarian wealth that Rhys described in 1832, just after the alleged emancipation created a new class of indentured servitude in Jamaica, acknowledges the unequal history of extraction and economic over-production beneath a veneer of plenty that led to the far more recent over-enrichment of the very impoverished lands, emended with fertilizer, that have shifted the coastal waters in an era of extreme weather, flooding, and coastal hurricanes. The sudden appearance of sargassum on our radar occurred as the landings of seaweed into the western tropical Atlantic–the size of landings exploded on Caribbean beaches, tied to extreme climate events of 2009-10, seemingly shifting winds and currents outside the usual confines of sargassum’s range that had confined its growth offshore in the belts of ocean currents. We have come to map sargassum now by local “inundation risk” of landfall, an addition to our coastal ocean placing an increased percentage of shoreline at increased risk, mapping the “risks” of inundation faced by beaches increasingly central to the economy of islands and coastal states, as if it were just suddenly entering our national sphere of influence and economic impact.

We may be tragically purblind to the deeper changes far beneath the flat blue surface of the Atlantic, by which in real-time maps we charge its arrival against swirling arrows of winds and currents, lacking a truly volumetric qualitative map of waters that fostered its rapid growth. If we are alarmed by the arrival of the Atlantic Sargassum Belt that is a new creature of the oceans, something that never encountered in the mid-Atlantic but now prominent from space, might we better map not only a flat ocean surface, but a shifting configuration of land to sea?

As our coastal waters are increasingly filled with accelerated algal growth, we have come to map shores and offshore waters as risk areas, neglecting how the growths are boosted by overabundant nutrients in river discharge from abundant use of industrial fertilizer, far outside the offshore waters to which the untold abundance of tawny sargassum was once primarily confined. As increasing nitrogen fills our coastal ocean, water acquires foreign hues of inkjet printers, as an overabundance of prolific algae clot coasts of the North Atlantic and are feared to wash across our shores. So, one fears, the arrival of the Great Atlantic Sargasum Belt.

The now-seasonal arrival of the macroalgae along Caribbean beaches, crowding out the stories white sands from the Bahamas to Mexico to Brazil, entangles shores, seas, and global ecosystems. If seaweed was an “inexhaustible wealth of wondrous forms” for Ernst Haeckle, whose hand-drawn images of radiolarians based on a thousand-fold magnification in microscopes provided grounds for the appreciation of natural forms–the abundance of seaweed is a problem show proportions we are not sure of how to observe, as it floats across the island, creating what once was seen–and is protected–as rich habitat for fishes, marine pelagics, birds, and microorganisms as yet the latest load of trash demanding disposal, leeching toxic sulfurs soon after it has washed ashore.

Coastal maps that foreground clear edges of shores fail to disentangle, or to blur, the way that the abundant generation of sargassum in our seas demands a new form of coastal mapping. In mapping their entry into national waters, we are often haunted by a metaphor of migration, fearing their impending landfall as a migration from abroad–across the ocean surface from Africa. But the long strands of sargassum that have flourished in our coasts was born in a bath of nutrients from rivers. The thirteen tons of free-floating macroalgae that favors temperate tropical oceans has gained new attention, enough to rouse the world from boredom at ocean swells. The fear of landfall grows as the sargassum bloom, now reproduced over a hundred-fold since appearing in 2011, is both fed by river discharge of the Congo and Amazon. While we map their seasonal arrival on the ocean horizon, as if it moves west to the south of the Sargasso Sea whose swirls are removed from shores, bound by ocean currents, the sargassum seems an invasive species we map as migrating. But in mapping the danger of the Atlantic Sargassum Belt by remote sensing, we are delinquent in failing to integrate its growing expanse to a global setting that has unintentionally saturated coastal oceans by anthropogenic nitrogen plumes, as extreme weather sends more and more manmade fertilizer in river discharge. Would a volumetric mapping help us to escape from the flat geographies by which we see the arrival of these floating mats as arriving on the sea from afar? It is all too easy to compartmentalize the “migration” of sargassum as a global artifact, destined once beached to release methane gases and hydrogen sulfide, a noxious smell toxic not only for respiratory health risks, but a unwanted potential public health risks for pregnant women.

Invasive Sargassum Belts Floating off Caribbean Island of St. Martin/Michel Vela (April 2018)

The half-rhyming couplets of Updike’s pentameter evoked perspective of a yachtsman more accustomed to hugging the shore than to high seas, and the lack of clear edges in the densely populated Sargasso Sea suggests a pool of algae without clear edges, bordered by islands from the Azores and Cape Verde in the east and surrounding Bermuda and the West Indies to the east, in a floating expanse that is hardly blue, even in Caribbean waters: we imagine the floating surface of sargassum, akin to Updike’s yacht, moves on the surface of the ocean, and map a two-dimensional image of it as advancing across the Atlantic Ocean below the equatorial current, but would do well to consider how a volumetric map of the seas might far better describe the huge macroalgal bloom.

Seaweed, Rachel Carson emphasized, inhabit an inter-tidal zone, if their “dark, mysterious forests” often “go down into deep water,” as evident in the giant key that are often cast ashore, if most kelp’s holdfasts are rooted to a rocky shore, and other inhabit the deep waters or polar sea. She believed that the sargassum of the central oceanic regions had entered the area bound by the strong flows of the Gulf Stream and North Atlantic Current from the coasts she loved, imagining that the “brown alga that lives attached to the rocks along the coasts of the West Indies and Floridas” were “torn away by storms, especially during the hurricane season,” to be picked up by the Gulf Stream and head north, bearing “as involuntary passengers . . . innumerable larvae of assorted species of marine creatures.” Although the Sargasso Sea becomes a destination itself of many pacific pelagics and fish, the prime role that she gives to the hurricanes in shaping the sea reveals a keen sense of the impacts of oceanic movement.

If the sargassum that was so feared by sailors in the Sea nurtures creatures attached to the “weedy jungle” to which they cling as a life raft, the lives of the sargassum by which the vast sea is defined as a land apart, inhabited by millions of tons of sargassum, seems a place where they may drift “endlessly, growing, reproducing vegetatively by a process of fragmentation,” outside time, perhaps including the very same weeds once passed by Columbus with fear. We are more reasonably afraid of the sargassum that has multiplied open the open ocean, to the south of the sea and the Great Atlantic Current, the 13.5 million metric tons of sargassum are poised to arrive at are coasts in far more time-sensitive ways. For as the sticky mats of meter-long strands of sargassum leave international waters, the very weeds that were the necessary habitat and spawning grounds for pelagic eels, sea turtle, fish and marine mammals, rather than offer “cover” as a floating island, is a threat to coastal habitat–and to the beaches of the shores where they are destined to make landfall. While we view our Florida beaches as sites for summer vacation, the arrival of seaweed is not only a nuisance, but the scale of the golden brown biomass offshore is a cause for global alarm.

“Seaweed Blobs Headed for Florida”/New York Times (Apri 19, 2023)

The appearance south of the Sargasso Sea of a flotilla of sargassum of unprecedented biomass may seem a new continent in the ocean, without clear bounds but of global significance worthy of preoccupation. Rather than bearing the creatures and microorganisms they host as distributed over ocean waters, invasive sargassum stands to threaten the reefs as they obscure transparent Caribbean waters as a layer of opacity, clogging the benthic habitat and, as they beach, releasing toxic vapors after two days. The amalgam of macroalgal kelp floats on the ocean’s surface, no longer bounded by currents’ flows, as the Sargasso Sea, but decaying soon after making landfall as it beaches ashore to pose problems of disposal we have no clear answer. Even south of the rich Amazon Reef System, the vital clustering of areas of rich species richness along South American shores that lie just within the continental shelf slope threaten to be covered and clotted by long weeds of sargassum that prevent sunlight from entering the blue caribbean waters of the Atlantic.

The flotilla of over thirteen and a half million tons of seaweed mapped by remote sensing have been cause for global alarm and anxiety as they seem to be entering our national waters in mid-March. The arrival of a long belt of sargassum seaweed, far below the channels that bound the swirling calm of that massive tide pool, demand a deep plumbing of its origins, as hidden as the deep sea that roils beneath the deceptive calm of the marine surface of the Sargasso Sea, with global ties as deep led Jamaican-born Jean Rhys to adopt the poetic figure of seaweed weaving a hidden tapestry across the Atlantic’s surface to span a global narrative from an English novel. Rhys, whose mother was Creole, reacted viscerally to Charlotte Bronte’s characterization of the madness of a creole first wife of her heroine, offering a backstory of the madness that led her to be confined that took its bearings form the plantations we do not see in Jane Eyre, but become a psychological backstory in what might be an early example of Atlantic history. Her title adapted the swirling Sargasso Sea that surrounds Jamaica, that Carson had characterized as spanning the ocean in a world apart, to ready readers for an interior geography that reveals the global reach of the cruelty of enslavement in the Caribbean plantation slavery in a postcolonial world, whose reach after, long emancipation, spans the worlds of Jamaica and the England: Wide Sargasso Sea orients readers to an encompassing toxic masculinity based on poisoned race-relations and intermarriage, almost titled The Creole, spools its story of an unruly web sprun from one side of the Atlantic to the other–from Jamaica and the island plantations–the trans-Atlantic slave trade mirrored in the first marriage of Rochester as a tragic prefiguration for the destiny of Jane Eyre, rather than confining Bertha to the attic as a madwoman who remains unknown but as Rochester’s first wild, creole wife.

The destiny of the first wife who Rhys felt a haunting absence in Jane Eyre stands at the center of the racial tensions the island of Jamaica was infected–moving from the tensions in speech and actions of maroons who had escaped slavery; blacks; mixed race and English. Her own perspective led Rhys to root a global drama of tortured patriarchal relations in plantation life, that circulated transatlantically to England, mimicking the currents of the actual Sargasso Sea. If Bermuda, in the Sargasso Sea, was believed by early moderns as “the Devils’ Island,” inhabited by devils and “feared and avoided by all sea travelers, above any place in the world,” per William Strachey, secretary-elect of Virginia, in the early seventeenth century, Rhys argues the fearsome nature of slavery itself in an Atlantic narrative too often elided by European novels, with origins in transatlantic trade, and the absent British landlords. Reading Rhys as an early critic of colonial globalism, one might find cues to read the biomass, not only against global warming and increasingly violent summer storms that flood regions recently converted to agrarian ends, a complex web that leads annual flooding to stream nitrogen fertilizer in plumes far beyond national waters or exclusive economic zones.

Even mores for the flotilla of sargassum mats mapped across the Atlantic. To map the biomass of the Sargassum Belt, we would do well to leave a two-dimensional mapping, and examine the interaction of this new species of floating sargassum that is arriving south and easterly of the swirling Sargasso Sea, but churning in the ambient waters of increased phosphorous as it approaches the America, that expand its reproduction. If the life cycle of the sargassum ends quite quickly when it comes ashore, exiting the nourishing oceanic habitat that led it to flourish, as it is beached ashore, as the tangled agal mass decomposes rapidly after landfall, its sulfur emissions are of a toxicity that cause acute respiratory problems, multiple side effects, especially for pregnant women; it will also, without being sunk, releases methane, a greenhouse gas that we are attempting to reduce–the biomass of over eleven million tons we are warned “is coming to shore” in coming months, as a 5,000 mile long train of macroalgae enters our national waters, stands to clog benthic habitats and coral reefs, and give of an obscuring stench as it fills the white sands of Caribbean beaches, although the economic impact on tourism is perhaps as two-dimensional way of mapping its arrival as seeing the massive belt as floating on the ocean’s surface, as Updike’s yacht.

The arrival of massive rafts of this deep green brown invader of clear waters is not only an opaque layer of seaweed belt, a displaced denizen of the High Seas, floating outside a region where its tangles are habitat and shelter to marine pelagics, from birds to fishes to sea-turtles to snakes to whales. The impending arrival the floating mass of the sargassum belt was mapped by NASA Earth Observer’s remote sensing has caused alarm, but the news growing mass this Spring has seemed to reach American news cycle several years late. While its notable growth was measured already ten years back, the two-dimensional mapping of the seaweed as a brown mass, visible from outer space, has become incorrectly seen by metaphorically cast in terms of migration. To be sure, the arrival of the toxic clotted algae raises questions of the inadequacy of such constructs as territoriality, sovereignty to manage the arrival of the abundant algal bloom washing ashore from international waters. But the multiple dimensions of a map of tis increased reproduction must begin from the anthropogenic waters it is encourages its massive growth, akin to steroids, as extreme storms are pushing more and more fertilizer from topsoil across the Amazon and Central America, creating a bath for its reproductive growth.

Unlike the mats of seaweed in tidal pools, rooted to hard surfaces by holdfasts, that Carson studied, these mats of macroalgae may seem to migrate seasonally to our shores. The news cycle depends on metaphors of migration, driven westward by ocean currents, “heading westward” that anticipate the dangers of its landfall as the rafts of kelp enter our coastal waters, far south of sargassum’s normal range. But the seasonality of their arrival, rather than being driven only by warming waters, or the best known “agent” of climate change, are keyed to river discharge that has fed sargassum both in the Atlantic much of the Atlantic ocean currents.

For the Caribbean islands stand again at the center of an entangled web of enriching soils to ease economic imbalances, this post suggests, as plumes of synthetic fertilizers enter the western North Atlantic, sending out nitrogen plumes to the Great Atlantic Current, rather than sargassum whipped by hurricanes from the island shores and coast of Florida to enter the Gulf Stream, as Carson believed, beyond national waters. The origins of Atlantic Sargassum Belt mirrors the new proximity that global warming has brought the seas around to over-fertilized agrarian lands, as tropical cyclones of increasing intensity drive river discharge rich with nitrogen out to sea to promote algal growth.

If the form of seaweed was long known to biologists, and even extolled as a rich offshore habitat, in the past ten to twenty years, the appearance of an entire new population living near the equator  is preoccupying many, as a new continent-sized mass stretching from the coast of western Africa’s coast to the Mexican coast to the Caribbean. It threatens to cover the shores of Caribbean islands, if it is not netted offshore. NASA’s Earth Observatory registered a “massive seaweed bloom in the Atlantic” approaching our shores, its biomass dissolved as pixels, poised to enter the American hemisphere and United States’ sphere of influence, America is late in noticing the biomass that has set new records for its seasonal appearance. But the a belt of rapidly reproducing macroalgae has hit the news cycle in anticipation of its landfall on American beaches.

Mapped from the Canaries to the West Indies, against a blank background, we remove the anomaly of its presence from the rich sediment of the coastal ocean that nourishes the Sargasso Sea, or the phosphorous that now feeds the coastal ocean. If the disturbingly high density of its presence–already thirteen million tons in mid-March–is isolated as the latest whacky disturbance of the Anthropocene, of unprecedented density, just below the currents that bound the Sargasso Sea, this new species of sargassum that seems to have sprung from the deep is fed by the boosted nutrients coursing in coastal oceans, and taken up by Equatorial currents, of nitrogen fertilizers that have altered the ocean waters.

If we map the sudden recent density of the new species of sargassum floating across the central Atlantic into the Gulf of Mexico as a disturbing violation of ocean boundaries that raises questions of the law of seas, its mass suggests a global presence we have trouble to process. If the Sargasso Sea was long cast as a site of mystery, by mariners who feared becoming prisoners of its swirling algae, unable to orient or right their course and becoming removed from solid ground, this blog post invites us to consider how land and sea are bridged not only in the Sargasso Sea itself, but the emergence of the Belt, and how much maps have served us well to comprehend its growth.

1. Rachel Carson, who has helped orient ourself to the life-filled edges of oceans, found the “Sea” helps us think differently about edges, if not oceanic expanse: the world that it presents is an assemblage, floating in blue transparent waters of the mid-Atlantic. The swirling sea blurs our sense of edges, and extends to the deep sea in a rich ecosystem, asking us to shift attention from edges, to call attention to the curious dynamics of the space. In 1870, a generation after Maury’s map, it was defined by quivering lines, akin to a protoplasm, in an age of increased cartographic objectivity– nervously drawn squiggles in the Atlantic, in the Mercator projection, bounded by the Gulf Stream and North Equatorial Currents, not clear lines. A site of fascination, its place name a different font from any other site, the quivering Sargasso Sea appears a region that shipping routes largely tend to avoid–the active energy of the region seems to be set against a divided globe.

Tons of sargassum–now some ten to twenty million tons of algal weed–floating outside the famous Sea have been likened to a floating continent in the mid-Atlantic, not swirling in the Atlantic around the outer islands of the Caribbean, but stretching from African coast.

The floating belt of sargassum algae now floating westward across the Atlantic is distinct from the Sea. If the Sargasso Sea was a site of nourishment and habitat, the weeds have merited attention of the news not only as a poor omen for summer beaches, but as an ocean we no longer know how to manage, and indeed a biome we are managing in increasingly poor ways. We map the floating algae as the latest unwanted assemblage born of climate change even though the seaweed’s growth would be curtailed by warming ocean water. But as ever increasing storms produce greater runoff fed the ocean with a bath of nitrogen-rich agrarian runoff, the increasing seasonal expansions of the belt below the Gulf Stream suggests a mystery of the Anthropocene.

Fears arrival of a mass of seaweed–visible from space, and mapped by remote sensing in all its biomorphic bulk of a boom of over twenty million tons–by some estimated to be above twenty-four million tons–seems less a bonanza than a symptom of the oceans’ poor health, and the latest source of anxiety. The roiling weeds seem a floating continent that is about to make landfall in America, a waiting time bomb for the release of all that seaweed’s waste and methane gas after it arrives on American shores. Mexican marines had removed some of the twenty million tons of brown sargassum since 2018, as its rapidly increasing biomass was linked to the growth of riverborn nitrogen both from fertilizer and carbon emissions in the coastal oceans linked by the mid-Atlantic Sargassum Belt, seaweed that emits a toxic sulfates soon after it is beached. The massive seasonal growth each spring and summer poses problems of the emission of smelly, toxic gasses, irritating the respiratory system and the eyes–evident in satellite imagery as the largest harmful algal bloom on the planet–that will live long in the ocean, but dies after two days on land, releasing toxic gas.  Its increasing global presence is yet another nightmare of the Anthropocene.

–that will decline only in the fall and winter months, when less sunlight arrives to encourage its marine growth.

In sharp contrast, Carson followed Thoreau in searching for the “tonic of wilderness” in the Sargasso Sea–as Thoreau found an antidote of sorts for civilization in the wild just outside of Concord, on the shores of Walden Pond, Carson meditated on the shoreless sea as a site of organic vitality, shifting American readers’ eyes from cities in ways that challenges us to move beyond a anthropocentric perspective or line of sight. It was hard to imagine how the curious Sargasso saw itself, or would position itself, seemingly diffused across space, as much as a bounded region, isolated apart from the syntax of maps of nation-states. In Matthew Fontaine Maury’s 1855 Physical Geography of the Sea, it is a grassy patch of seaweed, between the Canary Islands and Bermuda, in a gyre; in later ocean atlases it was a curious patch of green dots.

Sargasso Sea (1873, rep 1886)

Long seen as treacherous to sailors, the Sargasso Sea was long difficult to map because it was outside of our fundamental mapped categories of land masses, a floating surface. Perhaps because of its intriguing algal network without any clear bounds of land, the sea attracted the attention of Rachel Carson, who taught us much about the permeable edges of marine life, as “different from any other place on earth,” a place apart on the high seas, a sea with no shore. How did all these weeds arise in the mid-Atlantic? Were they born by winds that tore them from the shore?

The rich floating habitation marks a new space in the open ocean, its surface covered by ten million tones of tan sargassum as far as the eye can see. Carson called attention to the immense habitat of its large biomass–imagining a compounding of seaweed torn from the nearby shores, swirling within the protective bounds of ocean currents that nestled its flow. If seaweed is currently being re-conceived as a potential carbon sink, able to suck a disproportionate share of carbon from the rest of the ocean, the mats of seaweed and macro-algae that make up the Sargassum Belt may have been stimulated by the latest entry of -the seaweed that grew in the ocean was encouraged by the rich river sediment from the Amazon and other shores, sucked up into its gyre, as much as seaweed torn from its shores, that has allowed the protected algal mass to thrive. Shown by quivering lines in an age of increased cartographic objectivity, as a vital site, a place that was not only “apart” but preserved a wild that stood in contradistinction to the “depressing record of destruction” man has waged “against the earth he inhabits” that, she feared, diminished us all as humans. The relatively recent expansion of the GASB, however, seems an addition to that record–no longer sequestered in the ocean currents, but stranding on shores from the Caribbean to West Africa, where they threaten coastal ecosystems and biodiversity.

The whirling tawny golden of kelp that grew across the sea is truly a marvel and a place apart. The Sargasso Sea offered the illusion to sailors of a dangerous trap to Columbus, and many sailors mistakenly took its size as a pernicious danger for ships navigating the high seas–believing the fields of swirling algal fields were indications of reefs below on which their ships would risk running ashoal before their arrival at their destination, or were indeed just good omens land was nearby. The tawny mass is neither blue or blue-green, nor anything in between. The Sea was a marine wilderness that is largely unknown: Carson fancied that visitors to the Sea might see the same sea-plants that were seen by Columbus and his crew, as if the weeds were a surviving state of nature in the offshore. (Fifty years before she wrote, the Sea was a site of romance for adventure stories of the open ocean as an unknown edge of the earth.) Of a size that was indeed about as big as America itself, and vitality that demanded to be known, akin to an unknown floating continent. For the biodiversity that differs from any other ecological niche as grounds for spawning and foraging, a habitat that is also a destination for endangered pelagics.

Distinct from most mapped regions for lacking any boundary or shoreline, it is not defined by blue edges, by bound by oceanic gyres not able to be seen from sea. Outside the any government body, or Exclusive Economic Zone, it has limited legal protections. If the Sargasso Sea eludes national bias of mapping, outside international bounds, its fragile overlapping floating ecosystems were only recently protected due to a joint governmental accord–a conveyance that might be called the fruit of globalization–between the Bahamas, Bermuda, Dominican Republic, the Azores, British Virgin Islands, Principality of Monaco, United States, and United Kingdom, protecting the High Seas span across two million sq nautical miles recognized as complex locus of oceanographic migration. Often compared to a “golden rainforest,” in ways the mirror of the rainforest of Amazonia, its canopy stretches across the high seas, and extends deep into marine depths below 4500 meters, as challenging to map as it is to models of management for marine sanctuaries.

Perhaps because she was impressed by the poetic powers of Carson’s 1950 disentangling of the copious ecosystem of the Sargasso Sea, novelist Jean Rhys retitled the novel she was working set in the Caribbean that describes the first Mrs. Rochester, a revision of Jane Eyre, in a post-colonial optic, set just after the abolition of slavery in the sugar plantations of the English Empire. While the title replaced the more racially explicit The Creole, or, after a Caribbean spiritual, Gold Sargasso Sea–a plantation song–Wide Sargasso Sea captured a broad encompass of a tangled lineage, after the tangled seaweed, in the modernist masterpiece that expanded race, Caribbean history, and forced social marriages echoing the tangled violence sugar plantation, Coulibiri, across the Atlantic world. The Wide Sargasso Sea is a truly wild sea, marked by upwellings of rich minerals and churning up of long suppressed genealogies of the Atlantic slave trade, absent from Charlotte Brönte’s 1847 novel, Jane Eyre, set just after the Slavery Abolition Act of 1834 nominally liberated enslaved at plantations as Jamaica,–“No more slavery! She had to laugh.”–that is told in the optic of patriarchal domination. The “dark space” of the plantation and its un-English environment maps a backstory of the “Madwoman in the Attic” as a tortured space of female subjectivity spooling forth from a place where “Desire, Hatred, Life, Death came very close in the darkness. Better not know how close.

The plantation life of removed landlords in the West Indies islands form the previously unwritten background of the first Mrs. Rochester. And from the moment she overhears estate workers wonder at the impending plans of her stepfather–“‘a wealthy man who could take his pick of all the girls in the West Indies, and many in England too‘”–to remarry her mother, and gain wealth and an island estate in the Bahamas, the transaction of a removed landlord echoes a plantation economy built on the slave trade. The voiced fears about the marriage are a premonition of her abusive marriage to Rochester and indeed that of Jane Eyre–if Jane Eyre and Antoinette, the future Bertha Rochester, never meet in the world of the novel, the parallels in their lives take their spins form the global diaspora in which Rhys placed the novel’s layered dramatic tension. After nominal emancipation, the West Indies plantation remained a nexus of the sugar trade that defined wealth in the British Empire–as they did earlier of France–and were measured as lands of enrichment distant from the Paris or Greenwich meridians, diasporic settings of extraction on the edges of empire. If slavery had been abolished just before Rhys set her interior work, the absence of a clear land reform or legal structure not only left calypso a compelling form of social resistance and redress, in popular song and performance, as a running social commentary on the backstory of Jane Eyre, rooted in a quite often subversive Afrocentric orality, that offers a moral center to the tragic prehistory, akin to how an Afrocentric spirituality argued to offer Rhys’ heroines an “alternative epistemology”–if not an alternative spatiality to plot the colonial relations to the islands of the West Indies, viewed not only as a site to generate domestic wealth–as in Jane Austen’s 1812 Mansfield Park, but a sense of agency and moral redress against a stifling patriarchal silencing, echoing the derision of English institutions vocalized in transgressive song. Is it a surprise that the title took the name of a calypso that Rhys had penned herself with her cousin, in the French patois of the working class, also known to many of the colored mulatto élite? The revolt of slaves in the area of Suriname and Guyana had been romanticized as a trade in women by William Blake who illustrated the early printed history of John Gabriel Steadman–Narrative of the Five Years’ Expedition against the Revolt of Negroes of Suriname, in Guiana,

–setting the cruelty of enslavement against an exotic landscape was a stock trope.

The drive for extraction wealth from West Indies plantation demanded reorientation, and reorientation to the generation of imperial wealth in Jane Eyre, which silences Rochester’s first wife, Bertha, or Mansfield Park (1812), itself haunted by revolutions on overseas plantations, vaguely described “concerns of West Indian property” without faces. Rhys illuminated a critical backstory of domestic patriarchy, and logic of extraction that echoed in current attempts to resolve problems of dire poverty and promote an image or veneer of prosperity, in this case by the quick fix of emending new farmland by fertilizer to engineer agrarian self-sufficiency and a veneer of economic prosperity to the southern hemisphere. The arrival of fertilizer in West Africa, the clearcut lands of the Amazonia, and Mexico proceeded in the past decades under to offer food security to growing populations. As if to echo howJamaica, Antigua, and Barbados enriched European Atlantic empires, by extraction, investment in agribusiness that has transformed rainforest to fertilized plains has provided less of the positive effects it promised with increased amounts of nitrogen-rich fertilizer flushed in plumes out to sea, returning in a bounty of stranded Sargassum onto the shores that are providing the prime basis for economic security to many of the islands sugarcane was farmed.

J. Bellin, Petit Atlas Maritime (1764)

In our own maps of the arrival of sargassum belt, we must separate ourself from the perspective of removed landlords, reentering the Sargasso Belt seen as arriving from international waters, but examining it as a tortured product of over-fertilized land. Rhys revealed a rich patios the novel often neglected, in the English novel, mapping the exchange of brides as a wide sea of tangled webs across the Atlantic, familial and imperial, in a emotionally quite tangled racial origins of a heroine and English wealth from plantations that, as a gyre, spread its global web across the Atlantic, in ways that may have been informed by Rachel Carson’s earlier work on the Sargasso Sea as a hidden habitat situated between two continents, the exuberant growth of seaweed belts in recent years demand better mapping. The Sargasso Sea offered little or no safety form some swimmers off Jamaica, where sargassum makes its waters dangerous to many, and the arrival of sargassum in the mid-Atlantic is indeed a serious public health threat. If Rhys played with numbers of titles to capture the geography of the plantation and its extraction of wealth, including both That Wild Sea of Weeds where I was Wrecked (the voice of Antoinette, perhaps, or Rochester himself, whose voice is also in the novel) and That Wild Sea of Weeds where They Were Wrecked–gesturing to the geographic centrality of the Sargassum Sea that was imagined as a derelict space of swirling seaweed and ruins of old ships; the lonely plantation song that Rhys’ cousin from Dominica called a “Creole Song,” “Across the Gold Sargasso Sea, I watch my heart come back to me,” led her to consider Gold Sargasso Sea as a title, but the region where the trade winds grew and the cruel transatlantic slave trade spun out came to embody the social network her novel came to describe. Can we map the economic inequities that have, as much as the storms of global warming, created the latest marine anomaly?

It is as if the expansive proliferation of floating seaweed may be the unintended consequence of expanding investment in fertilized Caribbean soils, under the mantra of self-sufficient agriculture. While advanced by the World Bank as a quick fix for agricultural expansion, the global oceans are bearing the brunt of the region are investment of nitrogen excess in an era of severe weather, as the very same islands stand to bear the unintended brunt of a destabilized coastal ocean. If the world of global fertilizer has boosted crop production, the increased availability of nitrogen across the Atlantic basin has spread to the High Seas on both sides of the Sargasso Sea–increasingly under attack not only from plastics and ships that trawl for fish or cut across its kelp mats. Invertebrates, ocean upwelling, and transforming a “nursery habitat” for fishes into a site for massive harmful algal blooms. The abundant foliage of plants Charles Darwin had studied intensively by the samples he had captures in his 1835 voyages to Caribbean ports, the chain of life that he sought to decipher from the weeds suggested a stable balance of life that the abundance of Sargassum seemed to reveal to be radically and profoundly upset, if not destabilized and out of the possibility of management. If the new taxa of tropical plants held a stable place in Darwin’s herbarium, the placement of Sargassum seemed a disturbing displacement of the high seas to Caribbean waters.

Yet the scope of the global problem of abundant seaweed moving , if tied to World Bank subsidies for farming, suggests that since 2010, the availability of new nitrogen-rich nutrient sources provided a fertile bath for brown macroalgae across the Atlantic due to Spring river discharge with increasing quantities of nitrogen from agrarian runoff, unlike the historic upwelling of ocean floor sediment–evident, per LaPointe et al., in the presence of nitrogen after 2010 in new clustering of rafts of sargassum in the Gulf of Mexico or off Florida, unlike the sargassum in the Sargasso Sea.

Sargassum Reflecting Nitrogen Availability in Atlantic Basin, LaPointe, Bretton, Herring et al. 2021

The flotilla of sargassum mats are a substrate of a global economic inequalities, as much as climate change. It is a reflection of subsidized investment in agriculture that in recent storms brought increased runoff in the coastal oceans from increased fertilization with nitrogen, in an attempt to emend soil nutrients for food production–an over investment designed to foster to end economic inequality in the southern hemisphere, from West Africa to South America, begun in the development projects from the 1990s, before unforeseen extreme weather of downpours and hurricanes spilled the nitrogen into the pristine blue seas. We cannot remove it from the nutrients that not only entering the Caribbean in the form of agrarian run-off but the stirring up of deep water by cyclonic winds and hurricanes, creating levels of nitrogen in sargassum plants a third higher than average–35%, to be exact, by La Pointe’s measurements–at the same time as the rise of nitrogen:phosphorous ration in coastal waters has grown by 111%, with little collective attention. Ever since the topical storms of 2008 created more cyclonic activity than the Carribbean ever experienced–including Bertha, the largest tropical cyclone ever experienced in the North Atlantic–

–the damage costs of tropical cyclones that had grown to some $50B have only expanded since, leaving it increasingly irresponsible to invest in fertilizing topsoil to boost agrarian productivity.

We can point to the increased billions of investment in the production of expansive farmlands–an extractive model of industry, even in the name of economic self-sufficiency and food security. Annual delivery of millions of tons of nitrogen-rich fertilizer to unregulated private-sector fertilizer plants–FERTIMEX, private from 1991; Potassio do Brazil, which encouraged local mining of potash from the rain forest from indigenous lands, to blend with nitrogen and phosphorus–pollute coastal oceans with gypsum, phosphoric acid and sulfur dioxide as a result of enriching the agrarian lands with nitrogen fertilizer to enhance land productivity. Augmenting fertilizer use in the name of food security fed fertile use from Dominican Republic to Guatemala to Honduras leeches plumes of phosphorus in Caribbean waters–and may be increasingly irresponsible in an era of extreme storms. Are not the offshore rafts of rust-gold kelp a reminder of the poor return on investment in self-sufficient farming, and a wake-up call? Local strategic mining of fertilizer created ripples not only in fertilizer markets but disturbed the ambient composition of the ocean biome; continued soil emendation fed millions of tons of nitrogen in ocean currents, driving anomalous seaweed blooms.

Application of Nitrogen-Based Fertilizer in Global Harvested Crops (2011)

The extensive fields of olive-yellow to golden-brown floes are awesome in their majesty, and akin to a transatlantic economy of its own. We are apt to view the Belt of Sargasso as growing in the course of its arrival, but does the small stream bloom as it approaches nitrogen-enhanced water? If the nitrogen-rich plumes leaving the Amazon have been argued to enhance carbon sequestration in the North Atlantic sinking carbon into the deep sea, N2 fixation accelerates the reproduction of sargassum in more macroaglal mats than we are able to process ashore.

The so-called Sargasso Belt may be a massive breeding-ground for macroalgae acting as a counterweight to the historical function of the Sargasso Sea, and is creating an unforeseen “boom” in a bumper crop of macroalgae that led the Mexican Navy to send a flotilla of boats to harvest the weed as it arrived in national waters, removing by 2021 some 10,000 tons of sargassum from the ocean surface and farming more from the beaches of the Yucatán from 2011. The “counter-weight” to the increasing fertility of croplands suggests an extension of anthropogenic alteration of the environment far beyond the continental shelf, and expanded borders of nation-states we are accustomed to map as Exclusive Economic Zone (EEZ) that regulate exclusive economic use of ocean waters some two hundred kilometers out to sea.

If there will be a demand for both Mexico and the United States to “manage” the influx of biomass of the Sargassum Belt as they approach the continental shelf, broad changes in weather–often grouped as “climate change”–go unaddressed, and the reaction of extreme weather to enriching the land by nitrogen-boosting continue. Are the models of sovereignty and territoriality by which we understand relations to the ocean booby-trapped models that fail to capture the inter-relations between land and sea in an era of large-scale fertilization?

The “sea” is of loose borders, enclosed in the North Atlantic gyre, a slow-moving gyre bound by the Gulf Stream, Antilles and North Equatorial Current, out to the Canaries. Composed of weed of varied species, the “sea” is set off from tropical blue waters, but increasingly threatened both by seaweed harvesting and climate change. The drifting plants that multiply as they drift, a tangled covering of the high seas, move across the surface of the ocean, covering an extensive deep underwater community dependent on its webs. The subject of this post is the problem of mapping the magnitude of the weed, and interpreting those large belts of sargassum remote sensing have revealed floating westward to the Caribbean and Florida, whose size caused considerable alarm as the arrival of tons stinking piles on beaches to disrupt the summer tourist economy, rather than the disturbance of the ocean and dangers of artificially expanding nitrogen runoff entering the sea.

2. I’ll turn to the delicate nature of the feeding grounds and floating ecosystem of the Sargasso Sea itself, long bound by currents as a world apart, but which faces unique preservationist challenges. Mind-boggling in breadth and width, the tangled tawny mass of weed of many varieties was long thought pulled from shores of the islands of the Caribbean–Jamaica, Hispaniola, the Bahamas, or Florida–as much as an autonomous floating island. It is so hard to map in its complexity as an ecologic assemblage, let alone one of considerable volumetric depth; hard to map that perhaps because of this, few would imagine it able to be accorded the legal rights recognized for the Whanganui River in 2017, if it is the size of a nation, a sea as large as the United States. The recognition of the legal rights of that river protect the ecological integrity of the New Zealand river flowing into the Tasman Sea, both relied on for foods and as a travel route by Maori who live on its banks. Might it be possible to define the Sea as a biological entity, as much as an area of the open ocean, given the contribution that it makes to not only ocean health and habitat, but the oxygen generated by photosynthesis?

If the Whanganui River is protected as a site of longstanding indigenous settlement, the floating biomass of weed sequesters a disproportionate share of carbon of the world’s oceans, just off the North American continental shelf. Might it soon demand mapping to define its legal rights? The prospect is complicated as it lies in international waters. Yet the shift in legal thought by which the Whanganui River can bring suit for abusive pollution–or, indeed, be sued itself–is a landmark of environmental thought: the notion of its personhood inspired legal rights to be gained by the Ganges and Yamuna in Indian courts, if only temporarily. Is the forum of international courts may well provide a forum for the independence of the sargassum’s rights, in a global context, as much as the humans who have long failed to map its centrality in global climate adequately? A vital habitat swirling above abyssal plains and a rich mineral floor of metallic deposits, fed by mineral waters, the sea demands protection as an ecosystem.

Live Tracking of Shipping Routes in Northern Atlantic Ocean

The difficulty of mapping the integrity of the tangled mass is one issue. Or is the boggling growth of sargassum belts proceeding too quickly to try to start imagining its rights? The Sargasso “sea” is avoided by most routes. Distinguished by windless calms, ships’ captains long followed Columbus in mapping nautical routes around its mass until the maps were discovered by 1940 to be aggregations of plants, rafts reproducing far from land masses as a floating, edgeless mass, not only containing some of the same algae that was present in Columbus’ day, but preserving the same water in a the current’s effective enclosure or envelope.

But the mass is often still avoided by most trans-Atlantic ocean traffic, as of 2010–if this compilation of self-reported oceanic itineraries is far from comprehensive.

Voluntary Observing Ship (VOS) Program Data of 4500 Vessels in 2010/Roberts 2011

The absence of attention from this floating mass in open ocean waters, extending halfway into the Atlantic, the loosely bounded sea gained its name from millions of tons of floating sargassum, a rich and curious assemblage of animal life it fosters, challenging our abilities to map. It stands apart from the flow of any freshwater stream or demarcated edges and fixed bounds or shores; hardly a single polygon, the floating surface of brown algae are borne, the argued, by the Gulf Stream, that offers homes to crabs, shrimp, small fishes, sea slugs, edible roofs for sea turtles, or feeding grounds for laying larvae or webs or for flying fish and sea snakes to hide their eggs.

Like a new world lying in the middle of an ocean, a “weedy jungle” as Carson put it, a mobile “life raft” for others, it is a shelter for many to forage for food far below, and challenges our notion of surface, edge, or indeed ecological niche. The sargassum fields were either torn apart from the shore of Florida, or Caribbean land masses, or merely float rootlessly in open sea, fragmenting and enduring for up to centuries until they drift into less warmer or propitious areas of ocean, a tangled web of seaweed that lives off the land, a superfeeder site of marine habitat.

Sargasso sea map

Mapped something like the fertile inverse of the Great Pacific Garbage patch that is perhaps the prime surface-evidence of the Anthropocene, in the Sargasso Sea, an estimated ten million tons of seaweed floats unrooted, as if accumulated from distant coasts, far off of coastal waters, pulled in by oceanic currents, is hard to capture as a polygon. The site of the adventure stories of William Hope Hodgson, of vessels trapped in the sea’s flowing mass, a “cemetery of oceans,” prefiguring the Bermuda Triangle, where ships are attacked by underwater creatures, fearing the “thing in the weeds” in the “tideless sea”, its vitality reimagined as a site of danger, hiding marine monsters and sea demons within its weeds as the site of the last unknown, in pre-war adventure stories with a bit of H.G. Wells and Jules Verne, conjuring canny myths monsters emerging from its deeps.

And, although once avoided by ships, there seems evidence that despite some loose protection of the sargassum rafts in international laws of sea, the propellers of large transatlantic ships slicing the algal mats with increased regularity, with little protection accorded to the sea as a space to avoid, threatening to degrade the integrity of this delicate floating tan raft. The once-continuous floating rain forest is increasingly exposed to anthropogenic underwater noise from shipping traffic, difficult to quantify or map, but considered deeply disruptive to marine life.

As the Sargasso Sea has become a concentration of pollutants and plastics, sargassum has recently grown so dense since 2011 that images of abundance and fertility are replaced by fears of harmful algal blooms, from which marine life in the coastal oceans have increasingly suffered. The flow of plastics into the seas suggest an incursion of particulate matter difficult to map in detail, but raises the prospect of trying to disentangle the line, brittle pellets, already of some 3500 pieces per sq km, in the western Sargasso Sea, back in 1972, regularly ingested by fishes and microorganisms from radiolarians to diatoms, as well as pelagics, that as they depolymerize have made the algae pioneers of a plastisphere, that new marine entity of the Anthropocene, lying just within the Gulf Stream.

3. The abundant feeding grounds at a remove from coastal oceans have converted, in the remotely sensed mapsworthy of globalization and climate change, to a brown opacity charting the unwanted arrival of malodorous seaweed to clot the pristine sandy shorelines of the tropical Atlantic. Fears of over-accumulation and decomposition of rank sargassum along the coasts seems akin to the garbage of global warming, anthropogenic only by extension from living in a warming ocean. Its mass has become a nuisance and a danger to human health, if not ecosystems of the coastal ocean. The danger of these unwanted algae on our shores is something that Floridians are increasingly wrestling, feeling more than ever inconvenienced by international law that forbids the extermination of this broad edgeless mass.

The bloating of the sargassum belt to some 13 tones of floating kelp is larger this March than in any previous year on record. If the sargassum belt had already grown some 1,000% in size from 2011 by 2018, the bulk of its biomass has continued to grow each subsequent year, as it grew as long as the coastline of Brazil. Satellite registrations have tracked the sequential yearly growth of the belt’s floating mass, not as a feature of hidden fertility, but a massive seaweed bloom whose “load” is greater than in recent memory, even as it ominously threatens to arrive on our coastal shores. NASA’s tracks by remote sensing tools track the density of sargassum as it floats in a Great Atlantic Belt form earth observations of MODIS via satellite, as if unwanted visitors approaching the Americas, fed by the isequilibria of warming ocean temperature —

–and tracks its abundant density as a dark brown opacity, rather than a form of life. We may find ourselves frustrated by the inability given international conventions against capturing or culling the seaweed/algae as it approaches on open seas; the floating rain forest is protected as a habitat for endangered species, from sea turtles to multiple species of Atlantic eels who regularly return to its nourishing labyrinths, and its arrival in international waters–as if it was the latest casualty of globalization, unable to be stopped at our territorial waters!

Why so much loosely floating seaweed is carried by the oceanic currents seems in part to do with oceanic warming, the very warming that has multiplied the blooms of toxic coastal algal blooms. This is not a new manifestation of the “wide Sargasso Sea” long seen as a site of marvel, and enduring ecosystem, if the Sargasso Sea is hardly protected in international waters, its surface cut by the marine traffic that, unlike caravels, rent as the intensity and the speed of ships increased markedly in the post-war era from the 1950s to 1970s, feeding a global market of trade, before the arrival of micro plastics and anthropogenic detritus–and a disturbing accumulation of a plastisphereacross much of the more pristine waters of the Atlantic.

The intermingling of sargassum with plastics compromised its sensitive habitat, if not the wealth of nourishment and shelter that the marine sea forest has historically offered fishes, pelagics and other creatures. Carson speculated that the status of the Sargasso Sea may have been ripped by marine currents from shores, but what if Carson had it wrong? What if the swirling sea were fed by minerals that entered the rich coastal ocean, carried by the gyres into the mid-Atlantic, and feeding a swirling biomass? Have we been unintentionally injecting not only plastics into the Sargasso Sea, but fertilizer (phosphorous and nitrogen) into the coastal ocean, providing an overly nutrient-rich solution for the microalgae?

While Carson imagined the seaweed to have collected in the gyre, having departed the coastal environments she knew so well, the peculiar agglomeration of floating weeds, a gyre offering needed nourishment for beings from bacteria to pelagic eels and whales. But the gyre was itself nourished by waves of sediment, deposited from rivers as the Amazon into an offshore habitat.

The belt of sargassum floating across the Atlantic are unlike the Sea, nestled between the Gulf Stream and Equatorial Current, and lying safely offshore. Recent concern has grown around the question of whether the Sargasso Sea has been itself violated, ripped apart as coherent mats of habitat to a floating biomass of less fertile spawning or feeding ground, nestled between the recirculation of the Gulf Stream. Larger mats of sargassum appeared across the Atlantic ocean, spanning from West Africa to the Caribbean, as a “belt” from 2011, fed by nutrient-rich agrarian runoff, as much as warming waters, in the manner of those harmful algal blooms we have heard about ten years ago, as they showed up in remotely sensed maps and on our shores. For all the hullabaloo about the impending arrival of sargassum in the Great Pacific Belt, the appearance of blooms has become so common a public health risk of our coasts the EPA runs a dedicated line to report HAB’s in many state. In our new age of increased environmental anxiety, HAB’s are feared to harm water–not to mention how to protect your dogs from the toxic waters–in a health risk, and the health risk of Sargassum is indeed all too familiar, if of far greater proportions and biomass.

Is this not due to the change of the mineral-rich waters, now supersaturated by fertilizer pumped into the ground in a hope to increase agrarian productivity both on the Amazon and in Amazonia–now being converted into a deforested grazing field–and West African countries that have become hubs of processing fertilizer for independent farmers, in a bid for economic independence sponsored by such international entities as the World Bank? Driven by the hopes for economic investment and boosting productivity of “small farms” in the hope of economic self-sufficiency of the global south, the multiplication of fertilizer plants in hopes to feed a growing population has led to the greatest application of nitrogen-based fertilizer globally, and an increasing use of fertilizer based on nitrogen in Brazil, that doubled 2010-20, per Our World in Data, and is off the charts. The imbalances of oceans risk feeding macroalgae across the Atlantic at far greater scale than algae ever experienced, creating an unwanted bumper crop of algae on the oceans’ surface as we boost global agriculture, with pronounced blinders at risks of accelerating global ecological change in an era of extreme storms.

4. Fears of algal blooms led to remote tracking of sargassum as it leaves international waters. Recent satellite tracking of sargassum set a new standard of measurement for mapping of the algae’s biomass that among that now threatens to dump some 13 million tons of clumps of the brown tan ashore as it makes landfall. But do we have a sense of how generated the Sargassum making landfall has been generated in its new habitat? How large is the bloom off of West Africa that seems to have set the transatlantic voyage into motion, and how abundantly is it growing in the offshore waters? (International Law about sargassum is oriented to the Sargasso Sea’s protection; an apparent obstacle in harvesting the weed as it floats in international waters. The apparent frustration of legal protections that prevent the algae from being harvested on the high seas before it arrives, despite its increased density and size, make it hard to map the growth of its biomass over time, as a truly volumetric map might help provide.) Hopes to prevent the five-mile belt of sargassum from beaching have led some to propose environmentally-friendly solutions to avert off-gassing, by sinking the floating weed in deep waters.

Multiple theories have been proposed for its sudden appearance and growth outside the frame of currents: the outflow of industrial fertilizer from the Amazon river–the conversion of Amazonia, and destruction of a rainforest that historically has absorbed carbon dioxide to agricultural lands by large-scale deforestation–add unseen nutrients to the coastal waters of the Atlantic, increasing the levels of nitrogen in Caribbean waters to offer propitious conditions for expansion of a belt below the Antilles and North Equatorial current. In sharp contrast to these anthropogenic growth of a rise in the ration of nitrogen to phosphorus, driven by sewage and farm runoff, fears of ocean upwelling of minerals off the coast of west Africa may be a cause of the emergence of a flotilla of new sargassum–or arrival of sands from decertifying lands in the Sahara, spread the skeletons of ancient algae as far as the Caribbean, combined with smoke and ash, into coastal waters. While perhaps partly driven by the huge sandstorms of the Sahara that blew minerals of a Saharan Sand Layer as far as the Caribbean waters, rich in marine nutrients, in the midst of the pandemic in 2020, significantly after the first appearance of the sargassum belt ten years previous.

–the Saharan dust clouds that reached Caribbean waters June 15-25, 2020, while they long helped to fertilize the Amazon, form part of a multi-factorial shift in the sediment richness of global waters. Th feeding of phosphorous to ocean waters of the Atlantic basin contribute to the richness of the Sargasso Sea, no doubt, but the abundance that floated westward in 2020 are not able to describe the marked growth in density of the Sargassum Belt observed 2014-18, as it became a part of the Caribbean that raised particular alarm for the ocean anomalies of warming waters, particularly intense in the Gulf of Mexico, where much of the weed reproduced floating in the Yucatan Current.

This may be another way of mapping the Sargassum Belt as a global event. Did arrival of African dust that spewed across the Atlantic during the global pandemic another world-event spread across the very areas that soon stimulate algal blooms appear of such unprecedented intensity of growth? While the dust storm was a huge meteorological event itself closely tied to planetary warming, it overlapped with the seasonal discharge of nutrients to bring stimulate unprecedented algal growth.

If seeded with more intensity, perhaps, by the dust storms from the Sahara, the Godzilla Dust Storm able to be seen from outer space was yet another example about how land and sea are interrelated, in ways that our focus on a sense of the clear edges of land and sea fail to capture, to the extent that the flow of currents are no longer a fully self-contained system or circuit, bearing algae along the South Equatorial Current westward, in the manner we can map by clear vectors.

The challenged to mapping the size and the reasons for the appearance in consecutive seasons of the large biomass seems tied to the increase rainfall of that led to a huge increase in global surface-temperature from the pre-industrial era, and magnified the chance of massive rainfall by multiples of four or five in the Bahamas, and threefold in the Dominican Republic. Despite increased drought across South America, rainfall in Latin America grew as did intense rainfall driven by hurricanes and cyclones in wintertime, sending much fertilizer, poorly integrated in dry lands, to the coastal ocean. The belt of kelp runs below the Sea appeared as a new entity at the same time. If the macroalgae of the Sargasso Sea was once thought torn from the coastal waters of the West Indies and Florida, the size of this train of the Great Atlantic Sargassum Belt is a new strain of sargassum that threatens to wreck havoc on Floridian and Mexican shores, and throughout the Caribbean.

The evocation of an emergency has been long in coming. Only five years ago, it had astoundingly grown from earliest measurements to eleven million tons of floating kelp–the estimated size of the tangled weeds that comprise the Sea, now stretched across the Atlantic. Over some twenty years, the arrival of westward moving sargassum floats have been arriving in the Caribbean, unwanted global visitors impacted by ocean warming. While the upwelling in Africa has pointed to natural causes for newly sargassum, might one be mistakenly confusing Africa as a site of nature, not engineering? Has the dominant emergence of a focus on food security not increased the flow of nitrogen and phosphorous from subsidized agriculture not also contributed to flows of nitrogen and phosphorous, perhaps in combination with the emergence of sargassum species from the upwelling of ocean waters?

Fertilizer was subsidized by Presidential Initiatives in Nigeria since 2015, reaching the fields of some five million farmers by 2020, as other initiatives promising economic growth of agricultural sectors in led to importation of synthetic fertilizer across West Africa, leading to hopes to emend soil nutrients to expand productivity by World Bank initiatives, importing fertilizer to Dakar, Lagos, Abidjan, Port Harcourt, Lomé, and San Pedro, or in Senegal, Guinea, Côte d’Ivor, and Ghana; Côte d’Ivoire imported 525,000 metric tons from 2015, and West Africa importing and blending one and a half million MT annually by 2021, per Fertilizer Focus, creating a new addition to ocean ecosystems as an added bonus of sorts, whose impacts we may be charting as a resurgence of offshore macroalgae.

How much are the offshore nitrogen leaching into the coastal ocean the sources of the nourishment of such abundant sargassum yields? Whatever the mechanics, we are mapping an untold aggregation of floating mats of sargassum, dislodged from the gyre in which the Sea once lay, of a new species and vitality. The absence of clear edges–even the fuzzy bounds of Sargasso Sea–are cause for alarm, precisely because of their inability to be controlled in any offshore national space–as, for example, an oil leak–and the difficulty to combine ecological efforts across borders. The mats of sargassum poised to return to its beaches in future years, and to moor on Atlantic shores, stand to emit a noxious “sea” of offensive smells as they rapidly decay in the days after they reach the shore, releasing unhealthy sulfurs that not only mar the shores we like to imagine as pristine.

What else may have magnified the arrival of this belt? We must look for comparison–and points of needed orientation–to our own coastal oceans, and inland lakes, where algal blooms–and harmful algal blooms–have predictable been in recent news in quite alarming ways. If the increasing flow of sargassum across the ocean may be fed by the nitrogen runoff that leaves the Mississippi from farming regions that saturate coastal oceans–overloading them with nutrients to create more algal blooms. The growth of this new variety of sargassum–not present in the historic Sargasso Sea–may have, argued other oceanologists, respond to the change in oceanic currents themselves, and the deep mixing that led new nutrients to be rise from global ocean beds, feeding the migration of kelp: or did a new floating population of kelp arise, outside of the once loosely defined sector of the floating sea, floating seasonal algal blooms?

Do we need to try to map this global fear in more globally rooted terms, even as we map it as an oceanic anomaly revealed by remote sensing?

5. The possible environmental explanations for the Sargassum Belt are hard to reconcile with the immediate encounter with the prolific algal belt from 2018. The encounter of an oceanographer who studies the extent to which kelp’s intensive photosynthesis might be used to draw carbon dioxide from the air, was shocked at the meeting the large biomass. If he had conducted South Atlantic expeditions for a quarter of a century, he had never seen anything like the sudden shock of disorientation sailing into the Sargassum Belt: “one moment we were moving in the blue sea, then–BAM! It was all around the ship for tens, hundreds of meters.” remote sensing, but on the water. The algal bloom interrupted the ocean waters of unprecedented scale, as if it were indeed the Sargasso Sea being encountered for the first time, that the oceanographer only later discovered was a huge sargassum bloom monitored in satellite imagery since 2011 but has continued to explode in size.

The MODIS imagery may be, in short, as good an icon of globalization as any, from the rising runoff that has been encouraged in the name of greater agricultural productivity by the artificial enrichment of nutrients in new farmlands from West Africa to Amazonia, creating an immense biomass as a new Frankenstein in the middle of a new, warming world, where increased runoff defines the composition of coastal oceans. the acceleration from 2014 of the Sargassum Belt, while already detected in 2012, to be sure, of increasing tropical hurricanes and flooding, record levels of warming of ocean waters in the mid-Atlantic waters, and land temperatures far warmer than normal in South America and western Africa–multiplying events of extreme weather, closely tied to the increased rains brought by rising temperatures across the equatorial belt. The flash floods of 2023, and recent history of severe flooding in the Brazilian Amazon, destroying crop lands at the same time as the region is afflicted by severe drought that reduced overall river runoff, have produced increasing torrential rains and terrifying mudslides, after record rains that were the highest in Brazil’s history. Yet the essentially two-dimensional imaginary in which we map the apparent “approach” of a broadening belt of macroalgae to the shores of North and South America are perhaps less than helpful in incommensurable with our spaces of territorial governance.

The incommensurability of our concepts of territoriality with the confluence of extreme weather events, nitrogen flows to the coastal ocean, and warming waters have frustrated existing attempts to manage such hyperbolic algal growth as the Sargassum Belt. The isolation of sargassum density by remote sensing models helps to capture the intensity of blooms, facilitated by an unprecedented expansion of marine nutrients from both runoff and severe weather. The frustration we feel before the visualizations of time-lapse maps that suggest a cumulative growth of algae–mapped from 2012-18 in ways that cannot but recall the “flat” spatialities by which migration is imagined, a model of territoriality haunted by the actual building in the same year of the border wall–have infected the manner in which we map, visualize, and understand the approach as an escalation one which we are spectators, and have no control or impact.

The prime analogue for managing macro alga is the hyperbolic algal growth in the notorious dead zones of the Gulf of Mexico. The warming waters of this bioregion, endemic with algal blooms, is not driven by accumulation of arriving sargassum. But it mirrors the nourishment the Gulf Stream offers in ambient waters of that the sargassum encounters, that allows its tangled biomass to grow dense, as oceanic and atmospheric temperatures dramatically affect the marine ecosystem. If the dimensions of these extreme elements, foreign to our actual mapping systems–the accumulation of nitrogens in agricultural runoff from attempts to emend soil in the Amazonia; torrential rains that send more synthetic nutrients into the seas; toxic blooms of rapidly reproducing floating algae–can be mapped in microcosm in our own national waters, driven by warming waters. If warming waters can retard the sargassum’s growth in part, the floods that have driven plumes of nitrogen out to sea for hundreds of kilometers–far beyond the benthic environments of the continental shelf each Spring, due both to fertilization of land and replacement of rainforest with cattle ranching. Can the oceans suffer the increased boost of nitrogen plumes into the a warming Gulf Stream?

Sea Surface Temperatures of Gulf Stream/January, 2009

Warmer sea-surface temperatures in the Gulf Stream are not a false flag for the sudden blooms of macroaglae, but a context for understanding the state of the world’s largest holopelagic seaweed that we are still mapping primarily as a problem of coastal management–as if the ecological pollution derived from the seaweed arriving on our shores. We are late to map the arrival of this biomass with undue alarm, at the same time as hurricanes

To be sure, the sequestration of carbon sequestration in which plays such a disproportionate role in the global ocean; the Sea is fed by both upwelling of nutrients and warm water trapped in the North Atlantic Gyre, whose surface temperatures have been steadily rising. The floating Sargassum Belt is not rooted in the Gulf Stream or bound by it, but the path of its own transatlantic migration seems rooted in the highest sea-surface temperatures that causes its tangled webs to multiply.

gulf-stream-ocean-surface-winter-temperature-united-states-europe-arctic-circle

The new sargassum flourishes in regions of high sea surface temperatures, but seems fed by surface nutrients, rising to the ocean’s surface that accelerate their growth. The Atlantic Belt is an amalgam of hypermodernity, superficial floating set of plants, unlike the broad Sea that descends in a constellation of habitat some 4500 meters, offering shelter throughout its expanse to marine mammals.

The belt is far less friendly. Its arrival seems an unwanted invasion of global scale, and threatens to pollute the purity of dry, sandy beaches, that massive infertile absent ecosystem of our American shores, promoted by beach restoration, sand emendation, a site of pleasure. The sands of these beaches are often imported from islands in the Atlantic, as so many ecological engineering offering little habitat of any kind. Indeed, the absence of habitat that the belt provides–it is not being consumed, so much as reproducing in warm sunlight–is an unwanted result of experiment gone wrong: as much as a nuisance on pristine shores, the methane that will offgas from these tons of beached sargassum, removed from their oceanic habitat, will add yet another accelerator to global warming and climate change.

The arrival of the stream of kelp that is ominously moving across the Atlantic is not only a threat to beach lands, but to the environment. The over-abundant kelp seems one of the many aspects of overabundance global warming has produced, but which we have studied more in the home-grown variety.

6. The growth of offshore coastal seaweeds is not the same species as Sargassum, but we are all too familiar in recent years with algal blooms. The runoff of sediment and growing nitrogen load of rivers in estuaries of our largest coastal rivers–the Mississippi, the Potomac, the Columbia River–have delivered a larger nitrogen load in their discharge in recent years, delivering seasonal discharge from coastal rivers that has changed our sense of the offshore and nearshore in ways we are only beginning to map–but are increasingly present on the ground.

The Gulf of Mexico’s massive hypoxia zone has been measured as a consequence of freshwater runoff, from the Mississippi watershed, the river discharge that nourishes algae to extract almost all the oxygen from coastal waters hypoxic zone extending nearly 6,5000 sq miles, weed nourished not only by riverborn nutrients but growing sea surface temperatures.

The Gulf of Mexico Dead Zone

We are inclined to map increased coastal temperatures onto global warming, but are increasingly called upon to map chart the consequences of algal blooms as a danger of deoxygenated near coastal environments–altering near coastal ecosystems on which so many shore-dwellers depend–

Map of measured Gulf hypoxia zone, July 25-31, 2021.

But if we are much more ready to map the near-coastal in alarmist terms, perhaps this is because the national waters in which they lie have been mapped with far sensitivity, due to their proximity and integration with our economy, leading to news graphics that justly pronounce upon their danger as a sort of end of life for both fish and marine life in the nearshore coastal waters–

–and imagine the dangers of all that decomposing sargassum on the beaches, marring the deliveries of emendations of sand that try to prop up beaches as sites of economic vitality, which stand to be marred this summer by a smelly sort of return of the repressed, littering the shores with an unwanted abundance of decaying algal mats.

Before it arrives before our eyes, we have started to map its course, perhaps to try to ken the origins of all that stinky mess we have to sweep up and dispose. We’d do better to map the arrival tons of seaweed from a more global perspective, more oriented to global oceans and less guided by the landlubber’s beach shores. We would do well to do so through a truly global perspective, one encompassing Atlantic flows of kelp, even broader and wider than the truly expansive Sargasso Sea.

Surfside Ecotones

Shifting from a vision of blissed-out honeybees buzzing around a flowering birch tree in city gardens to the history of those buildings’ individual bricks, Campbell McGrath conjured a distinctly modern melancholy that imagines New York, reduced to an “archipelago of memory.” Taking poetic license to link buildings of man-made bricks once “barged down the Hudson,” from a hinterland of clay pits, quarries, and factories, to the future history of their disintegratation into the Atlantic, he asks we imagine their eventual return to silt: “It’s all going under, the entire Eastern Seaboard,” the Miami-based poet almost exuberantly prophesied, urging that we welcome the impending ecotonal intersection between land and sea that rising temperatures have wrought. As the pollen born on anthers from blossoms of cherry trees to hexagonal cells of their hives, the transience of buildings is not surprising from a poet who lives in a state where sea-level rise is four times the global rate. The atmospheric stresses of coastal condominiums near Miami is in the news again, as the catastrophic destruction is not apocalyptic in its own way.

In evoking the impending retreat of New York from its shores, McGrath imbued a sense of place with the stoic inevitability of monumental cataclysm. Global warming, sings the Miami-based poet, is an inevitability we must learn to welcome. Yet it is hard to acknowledge the inevitability of collapse on shorelines’ ever-changing ecotone. And it is hard to dislodge coastal California from the imagined vacation spot whose climate we could keep in aspic as a holiday space preserved in yellow photographs of old family albums. If Florida always seemed to stand in for salubrity and exceptionalism of sunny weather–its winter beaches promising fun and a promised rejuvenation for the vacationers and elderly alike as if the peninsula promised perpetual summer breezes and an abundance of sun–

Fabulous Florida–COOL in Summer! . . . WARM in Winter!

–where coastal waters promised easy access. The mythic geography that encouraged the construction of untold condominiums along the coast now seems a huge miscalculation. For as sand is eroded from those beaches with sea-level rise, we try to come to terms with an ecotonal shoreline that may not be able, with increased coastal flooding, to sustain their increased weight of condominiums’ coastal views. For saltwater permeation of the subsoil and inland ground risks eroding the very structures built to provide access to the sea, in a rush to build towers by the ocean that preceded the increase of saltwater inundation of the “land,” buildings whipped by hurricanes of unprecedented intensity, and storm surges that move ever more inland, the water table of the entire state is being pushed up in ways that will only remind us how much landfill the coast is actually built on.

We may have collectively adopted an attitude of near resignation at climate change and sea-level rise as intangibles by early 2020, after an unremitting sort of denialism of the “fraud” of climate change; McGrath’s poem preceded the terrifying collapse of the Surfside Towers evoked a shifting map of the nation as the Atlantic rose. The disaster grabbed national attention as the collapse of the residential building on the coast near Miami actually collapsed, pancaking in ways that attracted national alarm. And not for no reason. For the whole of the national seaboard seems compelled to move in exactly the same direction McGrath’s poem that sings of the eventuality of climate change. Leaving Washington, DC, the American Capitol secures more solid grounds in Kansas City and leaves the shores of Washington, DC, leaving “flooded tenements” or houseboats that are “moored to bank pillars along Wall Street.” As the Atlantic rises, few “will mourn for Washington,” and the once densely inhabited seaboard is abandoned, the coast reduced, in this dystopic flight of fancy, leaving the nation forced to shift the capitol to western Missouri in a search for more secure grounds.

The sudden collapse of half of the south tower of Champlain Towers in Surfside, FL, may be less apocalyptic in scope than the eastern seaboard. But it is now impossible to speak of offhand: we are agape mourning residents of the collapsed tower, trapped under the concrete rubble after the sudden pancaking of the southern tower. Without presuming to judge or diagnose the actual causes for the tragic sudden collapse of a twelve story condominium along the shore, the shock of the pancaking of floors of an inhabited condominium raises questions on how the many structural questions that surround Champlain Towers were overlooked. We ask in retrospective whether the certification process is adequate for forty year old concrete weight-bearing structures exposed to far more saltiness and saltwater than they were ever planned to encounter, they also raise questions of the increasingly anthropogenic construction of the coast. While the state of Florida long sold itself to the nation as a beach land–a site of people sprawled on towels soaking up the sun–the fluid nature of the coast as an ecotone bridging land and sea in changeable and changing ways suggests nothing less than the collision course between the increasingly fragile edge-land of the coast with the image of beachfront property that assuredly offers its future residents the health of the shoreline and a view of the sea.

The advertisement in a publication ostensibly dedicated to geographic education offered a map of the state as a map of pleasure, pools, white plaster towers, and folks in bathing suits, picnicking, golfing and playing beachball, as the sun gazed beatifically down on the state’s azure shores: the whole peninsula seemed a beach, or in fact was one, boasting room for all on 1,400 miles of mainland coastline.

“Fabulous Florida,” state advertisement in National Geographic (1952)

Although the realty industry and development business have sold the coastal experience of Florida as access to the shore, that increasingly popular prospect on the tranquil sea, the coast is in fact an ecotone–an intersection of land and sea, and increasingly porous one. We must recognize the coast as an increasingly overbuilt environment, and one poorly mapped as a divide between land and sea. The absence of the shore as a clear line should be more than evident not because of sea-level rise, but the density of shoreline skyscrapers and concrete residences crowding a strip between protected interior wetlands and the shore in southern Florida that is mostly built on former wetlands, but presented as a clear divide between land and see. We have encouraged the construction of a complex of coastal settlement as if it lay on solid ground, in concrete towers that are not impervious to weathering from the ocean air that washes over the shore, as we ignore the coastline’s vulnerability from ocean elements. If the porous nature of land and sea are viewed as problems of the ocean–the adverse effects of agricultural runoff or human waste on ocean currents beset by tidal algal blooms from the late 1970’s–due to agricultural runoff–and apparent in inland lakes, the fragility of the built environments we have made on the shore are not fully mapped for the very consumers sold residences promising ocean views, which are often poorly inspected due to developers’ greed. We have failed to map the coast as an ecotone–or acknowledge the increased permeation of the shore with saltwater, both underground and in the increasingly active weather systems that envelope the shore with saline ocean air, as we imagine the shore to be able to be mapped as a straight line, when it is not.

We continue to map “settlement” and “development” in terms of sold shoreslines, as if they were impermeable and not buffeted themselves. We have long mapped Florida by its beaches, and constructing homes for a market that privileged the elusive and desired promise of a beach view. Despite the allure that the state offers as a sort of mecca of beach settlement, meeting a market by offering vicarious live beach webcams in Florida and refusing, in the 2020 pandemic, to close beaches and beach life that promise an engine of economic activity, or imagine red flags by posing danger signs on the beaches.

Risks are similarly reduced or erased in the practice of coastal development for too long. We long recognized the instability of the shoreline communities, and not only from rising sea-level or surging seas. The lure of the beach continues, denying their actual instability, with the lure of otherworldly qualities as “edges” we imagine ourselves to be exhilarated by, if not released from day-to-day constraints, as a destination promising a new prospect on life.

The long distinction of the state by its beaches–its uncertain edges with the ocean–demand to be mapped and acknowledged as less of the clear line between land and sea than not only a permeable boundary, but of a complex geography vulnerable to both above ground flooding and underground saltwater incursion, sustained exposure to salty air, winds of increased velocity, and an increasing instability of its shores that have long been a site attracting increased settlement. Can one view the ocean surrounding the shores not only as a quiescent blue, but as engaged with the redrawing of the line of the shore itself as a divide long seen as a stable edge of land and sea?

From the increased tensions of hurricanes from the warming oceans, to underground saltwater incursion, to a constant beach erosion and remediation, the beaches we map as lines are coastal environment whose challenges engineers who valued the economy and strength of concrete towers did not imagine. The combination of the influx of salty air, the erosion and replacement of beach “sand”, and increased construction of condominium have created an anthropogenic shore that demands to be examined less as a divide between land and sea than a complex ecotone where salt air, eroding sand, karst, and subsoil weaknesses all intersect, in ways that the mitigation strategies privileging seawalls and pumping stations ignore. As importation of sand for Miami’s “beach” continues, have we lost sight of the increasingly ecotonal organization of Florida’s shores?

The point of this post is to ask how we can best map shifts in the increasingly anthropogenic nature of Miami’s shores to come to terms with the tragedy of Champlain Towers, to seek us to remain less quiescent in the face of the apparent rejiggering of coastal conditions as a result of climate change beyond usual metrics of sea-level rise. For the collapse of Champlain Towers provides an occasion for considering how we map these shores, even if the forensic search for the immediate structural weaknesses that allowed the disaster of Champlain Towers to occur.

Miami Beach has the distinction of the the lowest site in a state with the second-lowest mean elevation in the nation, and ground zero of climate change–but the drama of the recent catastrophic implosion of part of Champlain Towers should have become national news as it suggested the possible fragility of regions of building that are no longer clearly defined as on land or sea, but exist in complex ecotones where the codes of concrete and other building materials may well no longer apply–or, forty years ago, were just not planned to encounter. While we have focussed on the collapse of the towers with panic, watching the suddenly ruptured apartments akin to exposed television sets of everyday Americans’ daily lives, the interruption of the sudden collapse of the towers is hard to process but must be situated in the opening of a new landscape of climate change that blurs the boundary between land and sea, and challenges the updating of building codes for all coastal communities. The old building codes by which coastal and other condominiums were built by developers in the 1970s and 1980s hardly anticipated to being buffeted by salty coastal air, or having their foundations exposed to underground seepage or high-velocity rains: the buildings haven’t budged much, despite some sinking, but demand to be mapped in a coastal ecotone, where their structures bear stress of potential erosion, concrete cracking, and an increased instability underground, all bringing increased dangers and vulnerabilities to the anthropogenic coast in an era of extreme climate change.

Rescue Workers in Surfside Disaster Attempt to Find Survivors in Champlain Tower South

A small beachside community bordering the Atlantic Ocean just north of Miami Beach, on a sandy peninsula surrounded by Biscayne Bay and the Atlantic, the residential community is crowded with several low-rise residential condominiums. While global warming and sea-level rise are supposed to be gradual, the eleven floors of residential apartments–a very modest skyscraper–that collapsed was immediate and crushing, happening as if without warning in the middle of the night. As we count the corpses of the towers residents crushed by its concrete floors, looking at the cutaway views of eerily recognizable collapsed apartments, we can’t help but imagine the contrast between the industry and care with which bees craft their hives of sturdier wax hexagons against the tragedy of the cracked concrete slab that gave way as the towers collapsed, sending multiple floors underground, in a “progressive collapse” as vertically stacked concrete slabs fell on one another, the pancaking multiplying their collective impact with a force beyond the weight of the three million tons of concrete removed from the site.

This post seeks to question if we have a sense of the agency of building on the shifting shores of Surfside and other regions: even if the building codes for working with concrete have changed –and demand changing, in view of the battering even reinforced concrete takes from hurricanes, marine air, flooding, and coastal erosion and seawater incursion near beachfront properties–we need a better mapping of the relation of man-made structures and climate change, and the new coasts that we are inhabiting in era of coastal change, far beyond sea-level rise.

As we hear calls for the evacuation of other forty-year old buildings along the Florida coast, it makes sense to ask what sort of liability and consumer protection exists for homeowners and condominium residents, who seem trapped not only in often improperly constructed structures for an era increasingly vulnerable to climate emergency, but inadequate assurances or guarantees of protection. We count the corpses, without pausing to investigate the dangers of heightened vulnerability of towers trapped in unforeseen dangers building in coastal ecotones. Indeed, with the increased dangers of flooding, both from rains, high tides, storm surges, and rising sea-lelel, the difficulty of relying on gravity for adequate drainage has led to a large investment in pumping systems in the mid-beach and North Miami area. The sudden collapse of the building, which civil engineers have described as a “progressive collapse,” as occurred in lower Manhattan during the destruction of New York’s World Trade Center, the worst fear of an engineer, in which after the apparent cracking of the structural slab of concrete under the towers’ pool, if not other structural damage. The thirteen-story building, located steps from the Atlantic ocean, was part of the spate of condo construction that promised a new way of life in the 1970s, when the forty year-old building was constructed; although we don’t know what contributed to the collapse that was triggered by a structural vulnerability deeper than the spalling and structural deterioration visible on its outside, the distributed liability of the condominium system is clearly unable to cope with whatever deep structural issues led to the south tower’s collapse.

Americans who hold  $3 trillion worth of barrier islands and coastal floodplains, according to Gilbert Gaul’s Geography of Risk, expanding investment in beach communities even as they are exposed to increased risk of flooding–risks that may no longer be so easily distributed and managed among condominium residents alone. And the collapse of the forty year old condominium tower in Surfside led to calls for the evacuation and closure of other nearby residences, older oceanfront residences vaunted for their close proximity to “year-round ocean breezes” and sandy beach where residents can kayak, swim, or enjoy clear waterfront. The promise that was extended by the entire condominium industry along the Florida coast expanded in the 1970s as a scheme of development that was based on the health and convenience of living just steps from the Atlantic Ocean, offering residences that have multiplied coastal construction over time. While the tragic collapse suggests not only the limits of the condominium as a promise of collective shouldering of liabilities, it also reminds us in terrifying ways of the increased liabilities of coastal living in an age of overlapping ecotones, where the relation between shore, ocean spray, saltwater incursion, and are increasingly blurred and difficult to manage in an era of climate change–as residences such as the still unchanged splashpage of Champlain Towers South itself promise easy access to inviting waters that beckon the viewer as they gleam, suggested exclusive access to a placid point of arrival for their residents that developers still promise to attract eager customers.

Although the shore was one of the oldest forms of “commons,” the densely built out coastal communities around north Miami, the illusion of the Atlantic meeting the Caribbean on Miami’s coasts offers a hybrid of private beach views and public access points, encouraging the building of footprints whose foundations extend to the shores, promising private views of the beach to which they are directly facing, piles driven into wetlands and often sandy areas that are increasingly subject to saltwater incursion. The range of condominiums on offer that evoke the sea suggest it is a commodity on offer–“surfside,” “azure,” “on the ocean,” “spiaggia“–as if beckoning residents to seize the private settlement of the coasts, in a burgeoning real estate market of building development has continued since the late 1960s, promising a sort of bucolic resettlement that has multiplied coastal housing developments of considerable size and elevated prices. Is the promise to gain a piece of the commons of the ocean that the real estate developers have long promoted no longer sustainable in the face of the dangers of erosion both of the sandy beaches and the concrete towers that are increasingly vulnerable not only to winds, salt air, and underwater inland flow, but the resettlement of sands from increased projects of coastal construction?

If collapse of the low-rise structure that boasted proximity to the beach may change the condo market, the logic of boasting the benefits of “year-round ocean breezes,” has the erosion of the coast and logic of saltwater incursion in a complex ecotone where salty air, slather flooding, and poor drainage may increasingly challenge the stability of the foundations of the expanding market for coastal condos–and to lead us to question the growing liability of coastal living, rather than investing in seawalls and beach emendation in the face of such a sense of impending coastal collapse, as the investment in concrete towers on coastal properties seem revealed as castles in the sand.

If the architectural plans for the forty-year-old building insured adequate waterproofing of all exposed concrete structures, in an important note in the upper left, the collapse left serious questions about knowledge of the structural vulnerability in the towers, whose abundant cracking had led residents to plan for reinforcement. The danger that Surfside breezes sprayed ocean air increased the absorption of chloride in the concrete over forty years that it cracked, allowing corrosion of the rebar, and greatly weakening the strength of supporting columns that had born loads of the tower’s weight, significantly weakening the reinforced concrete. The towers had been made to the standards of building codes of an earlier era, allowing the possible column failure at the bottom of the towers that engineers have suggested one potential cause for collapse in ways that would have altered their load-bearing capacity–the lack of reinforced concrete at the base, associated with the collapse of other mid-range concrete structures often tied to insufficient support and reinforced concrete structures. The dangers of corrosion of concrete, perhaps compounded by poor waterproofing, of cast in place concrete condominium towers in the 1970s with concrete frames suggest an era of earlier building codes, often of insufficient structuring covering of steel, weaknesses in reinforced concrete one may wonder if the weathering of concrete condominiums could recreate between columns and floors–and potential shearing of columns to the thin flat-plate slabs whose weight they bore, creating a sudden vertical collapse of the interior, with almost no lateral sideways sway.

Even as we struggle to commemorate those who died in the terrifying collapse of a residential building, where almost a hundred and sixty of whose residents seem to be trapped under the collapsed concrete ruins of twelve floors, we do so with intimations of our collective mortality, that seems more than ever rooted in impending climate disasters that cannot be measured by any single criteria or unique cause. The modest condo seems the sort of residence in which we all might have known someone who lived, and its sudden explosive collapse, without any apparent intervention, raises pressing questions of what sort of compensation or protection might possibly exist for the residents of buildings perched on the ocean’s edge. Six floors of apartments seem to have sunk underground in the sands in which they will remain trapped, in sharp contrast to the bucolic views the condominium once boasted.

Miami Beach Coast/Alamy

While the apparent seepage in the basement, parking garage, and Champlain South that ricocheted over social media do not seem saltwater that seeped through the sandy ground or limestone, but either rainwater or pool water that failed to drain adequately, the concrete towers that crowd the Miami coastline, many have rightly noted, have increasingly taken a sustained atmospheric beating from overlapping ecotones of increased storms, saltwater spray, and the underground incursion of saltwater. If the causality of the sudden collapse twelve stories of concrete was no doubt multiple, the vulnerability to atmospheric change increased the aging of the forty year old structure and accelerated the problems of corrosion that demand to be mapped as a coastal watershed.

The bright red of coasts in the below map seems to evoke a danger sign that is intended to warn viewers about heightened increased consumer risk, from the Gulf Coast to Portland to Florida to the northeast, as sustained exposure to corrosive salt increased risk to over-inhabited coasts, particularly for those renting or owning homes in concrete structures built for solid land but lying in subsiding areas along a sandy beach. Indeed, building codes have since 2010 depended on the gustiness of winds structures would have to endure and not only along the coast, as this visualization of minimum standards across the state–mandating the risks coastal housing needs to endure–a green cross-hatched band marking new regions added to endure 700-year gusts of wind, inland from Miami.

Florida received a low grade for its infrastructure from the incoming administration of President Biden–he gave the state a “C” rather grudgingly on the nation’s report card as he promoted the American Jobs Plan in April, focussing mostly on the poor condition of highways, bridges, transit lines, internet access, and clean water. The shallow karst of the Biscayne aquifer is a huge threat to the drinking supplies of the 2.5 million residents of Miami-Dade County, but the danger of residences has been minimized, it seems, by an increasingly profitable industry of coastal building and development. While incursion of saltwater inland remains a threat to potable water, the structural challenges of the new As coastal Floridians have been obsessed with working on pumps to empty flooded roads to offshore drains, clearing sewer mains, and moving to higher grounds, the anthropogenic coastal architecture of towering condominiums offering oceanfront views have been forgotten as a a delicate link whose foundations and piles bear the brunt of the ecotonal crossfire of high winds, saltwater, and salty air that contributed to the “abundant cracking” of concrete that is not meant to withstand saltwater breezes, underground incursion, or the danger of coastal sinkholes in the sandy wetlands where they are built.

It is hard to look without wincing at a visualization designed to chart cost effectiveness by which enhanced concrete would mitigate the damage of hurricanes and extreme weather to coastal communities.

The below national map colors much the entire eastern and southeastern seaboard red, as a wake-up call for the national infrastructure. In no other coastal community are so many concrete structures so densely clustered than Florida. If designed and engineered for land, they are buffeted by salty air on both of its shores, from the Gulf of Mexico and the Atlantic; wind speeds and currents make the coast north of Miami among the saltiest in the world–as high winds can deliver atmospheric salts at a rate of up to 1500 mg/meter, penetrating as afar as one hundred miles inland that will combine with anthropogenic urban pollutants from emissions to construction–creating problems of coastal erosion of building materials, as much as the erosion of beaches and coast ecosystem threatened in Miami by what seems ground zero in sea-level rise, and, as a result, by saltwater incursion, and indeed the atmospheric incursion of salty air–concentrations of chloride that is particularly corrosive to concrete.

And is the exposure of concrete structures across southern Florida to salty air destined to increase with trends of rising sea-levels, already approaching five inches, and projected to deviate even more from the historical rate along the coast, exposing anthropogenic structures from skyscrapers to residences to increased flow of saltwater air?

We are all mourning the collapse of the Surfside FL condominium whose concrete pillars were so cracked and crumbling to expose rusted rebar exposed to salt air. Built on a sandbar’s wetlands, reclaimed as prime property, the town seems suddenly as susceptible to structural risk akin to earthquakes, posing intimations of mortality fit for an era of climate change. The collapse of the southern tower in the early morning of pose questions of liability after the detection of the cracked columns, “spalling” in foundational slabs of cement that allowed structural rebar within to deteriorate with rust that will never sleep. Its collapse poses unavoidable questions of liability for lost lives and unprecedented risk of the failure to respond to concrete cracking, but the ecotonal nature of the Florida shore, whose stability has been understood only by means of a continuing illusion as a clear division between land and sea, as if to paper over the risk of a crumbling shore, where massive reconstruction projects on its porous limestone expose much of the state to building risk of sinkholes and the sudden implosion or subsidence of the sandy shore in a county that was predominantly marshlands, and the inland incursion of salty air that make it one of the densest sites of inland chloride deposition–up to 8.6 kg/ha, or 860 mg/sq meter–and among the most corrosive conditions for the coastal construction of large reinforced concrete buildings facing seaward.

While coastal subsidence may have played a large role in the sudden instability of the foundations that led the flat concrete slab on which the pool to crack, and leak water into the building’s garage in the minutes before it collapsed, the question of liability for the sudden death of Surfside residents must be amply distributed. For the question of liability can be pinned to untimely review process, uncertainty over the distribution of costs for repairs to condominium residents, and the failures of proper waterproofing of concrete as well as a slow pace of upkeep or repairs, the distributed liability raises broad questions of governance of a coastal community. The proposed price of upkeep of facade, inadequate waterproofing, and pool deck of $9.1 million were staggering, but the costs of failure to prevent housing collapse are far higher–and stand to be a fraction of needed repairs for buildings across Miami-Dade County over time.

The abundance of concrete towers in Miami-Dade county alone along the coast poses broad demands of hazard mitigation for which the Surfside tragedy is only the wake-up call: the calls from experts in concrete sustainability at MIT’s Concrete Sustainability Hub (CSHUB) for a reprioritization of preparation for storms from the earliest stages of building design has called fro changes in building codes that respond to the need for increased buffeting of coastal concrete buildings, arguing that buildings should be designed with expectations of increased damage on the East and Gulf coasts that argue mitigation should begin from the redesign of cement by a better understandings of the stresses in eras of climate change that restructuring of residential buidings could greatly improve along the Florida coast–especially the hurricane-prone and salt incursion prone areas of Miami-Dade county both by the design of cement by new technologies and urban texture to allow buildings to sustain increased winds, flooding, and salt damage. Calculated after the flooding of Galveston, TX, the calculation of a “Break Even Mitigation” of investing in structural investment of enhanced concrete was argued to provide “disaster proof” homes, by preventing roof stability and insulation, as well as preventing water entry, and saltwater corrosion in existing structures, engineering concrete that is more disaster resistant fro residential buildings in ways that over time would mitigate meteorological damage to homes to be able to pay for themselves over time; the “Break-Even Mitigation Percent” for residential buildings alone was particularly high, unsurprisingly, along the southern Florida coast.

1. Although discussion of causes of its untimely collapse has turned on the findings of “spalling,” ‘abundant” cracking and spiderwebs leading to continued cracks in columns and walls that exposed rebar to structural damage has suggested that poor waterproofing exposed its structure to structural damage, engineers remind us that the calamity was multi-causal. Yet it is hard to discount the stresses of shifting ecotones of tides, salty air, and underground seepage, creating structural corrosion that was exacerbated by anthropogenic pollution. The shifting ecotones create clear surprises for a building that seems planned to be built on solid ground, but was open to structural weaknesses not only from corrosion of its structure but to be sinking into the sandy limestone on which it was built–opening questions of risk that the coastal communities of nation must be waking up to with alarm, even as residents of the second tower are not yet evacuated, raising broad questions of homeowner and consumer risk in a real estate market that was until recently fourishing.

The apparent precarity of the pool’s foundations lead us to try to map the collapsed towers in the structural stresses the forty year old building faced in a terrain no longer clearly defined as a separation between land and sea, either due to a failure of waterproofing or hidden instabilities in its foundations. And despite continued uncertainty of identifying the causes for the collapse of the towers, in an attempt to gain purchase on questions of liability, the tower’s collapse seems to reflect a zeitgeist of deep debates about certainty, the anxiety with which we are consuming current debates about origins of its collapse in errors of adequate inspection or engineering may conceal the shaky foundations of a burst of building on an inherently unstable ecotone? While we had been contemplating mortality for the past several years, the sudden collapse. of a coastal tower north of Miami seemed a wake-up call to consider multiple threats to the nation’s infrastructure. Important questions of liability and missed possibilities of prevention will be followed up, but when multiple floors of the south tower of the 1981 condominium that faced the ocean crumbled “as if a bomb went off,” under an almost full moon, we were stunned both by the sudden senseless loss of life, even after a year of contemplating mortality, and the lack of checks or–pardon the expression–safety nets to the nation’s infrastructure.

The risks residents of the coastal condominium faced seemed to lie not only in failures of inspection and engineering, but the ecotonal situation of the overbuilt Florida coast. Residents seemed victims of the difficulties of repairing structural compromises and damage in concrete housing, and a market that encouraged expanding projects of construction out of concrete unsuited to salty air. As much as sea-level rise has been turned to visualize the rising nature of risk of coastal communities that are among the most fastest growing areas of congregation and settlement, as well as home ownership, the liability of the Surfside condominium might be best understood by how risk is inherent in an ecotone of overlapping environments, where the coast is not only poorly understood as a dividing line between land and water, but where risk is dependent on subterranean incursion of saltwater and increasing exposure inland to salt air, absent from maps that peg dangers and risk simply to sea-level rise? The remaining floors of the partly collapsed tower were decided to be dismantled, but the disaster remains terrifyingly emblematic of the risks the built world faces in the face of the manifold pressures of climate change. While we continue to privilege sea-level rise as a basis to map climate change, does the sudden collapse of a building that shook like an earthquake suggest the need to better map the risks of driving piles into sandy limestone or swampy areas of coastal regions exposed to risks of underground seepage that would be open to corrosion by dispersion of salt air.

The search for the bodies of residents buried under the rubble of collapsed housing continued for almost a full week, as we peered into the open apartments that were stopped in the course of daily life, as if we were looking at an exploded diagram–rather than a collapsed building, wondering what led its foundations to suddenly give way.

As I’ve been increasingly concerned with sand, concrete, and the shifting borders of coastal shores, it seemed almost amazing that Florida was not a a clearer focus of public attention. The striking concentration of salts that oceans deposited along the California coast seemed a battle of attrition with the consolidation and confinement of the shores. Long before Central and Southern Florida were dredged in an attempt to build new housing and real estate, saltwater was already entering the aquifer. As the Florida coast was radically reconfigured by massive projects of coastal canalization to drain lands for settlement, but which rendered the region vulnerable to saltwater, risking not only contaminating potable water aquifers, but creating corrosive conditions for concrete buildings clustered along the shores of Miami-Dade County across Fort Lauderdale, Pompano Beach, as much of Florida’s coast–both in terms of the incursion of saltwater and the flow of salty air, that link the determination of risk to the apparent multiplication of coastal ecotones by which the region is plagued, but are conceptualized often only by sea-level rise. Even as Miami experienced a rise in sea-level some six times the rate of the world in 2011-2015, inundating streets by a foot or two of saltwater from Miami to Ft. Lauderdale was probably a temporary reflection of atmospheric abnormality or a reflection of the incursion of saltwater across the limestone and sand aquifer, lying less than two meters underground. Did underground incursion of saltwater combine with inland flow of salty air in dangers beyond tidal flooding in a “hotspot” of sea-level rise? One might begin to understand Surfside, FL as prone to a confluence of ecotones, both an overlapping of saline incursion and limestone and its concrete superstructure, and the deposit of wet chloride along its buildings’ surfaces and foundations, an ecotonal multiplication of risk to the consumers of buildings that an expanding real estate market offered along its pristine shores.

Approximate Inland Extent of Saltwater Penetration at Base of Biscayne Aquifer, Miami-Dade County, USGS 2018

While the inland expansion of saltwater incursion and penetration has become a new facet of daily life in Miami-Dade County, where saltwater rises from sewers, reversing drainage outflow to the ocean, and permeates the land, flooding streets and leaving a saltwater smell in the air, the underground penetration of saltwater in these former marshlands have been combatted for some time as if a military frontline battle, trying to beat back the water into retreat, while repressing the extent of the areas already “lost” to the sea. If the major consequences of such saltwater intrusion are a decay. and corrosion of underground infrastructure as water and sewage pipelines, rather than the deeply-set building foundations of condominiums that are designed to sustain their loads, the presence of incursion suggests something like a different temporality of the half-life of concrete structures that demands to be examined, less in terms of the damage of saltwater incursion on building integrity, than the immersion of reinforced concrete in a saline environment, by exposing concrete foundations to a wetter and saltier environment than they were built to withstand, and exposing concrete to the saline environment over time.

As much as we have returned to issues of subsidence, saltwater incursion, and other isolated data-points of potential structural weakness in the towers, the pressing question of the temporality of building survival have yet to be integrated–in part as we don’t know the vulnerability or stresses to which the concrete foundations of buildings perched on the seaside are exposed. The very expanse of the inland incursion of saltwater measured in 2011 suggests that the exposure to foundations of at least a decade of saltwater have not been determined, the risks of coastal buildings and inhabitants of the increased displacement of soils as a result of saltwater incursion or coastal construction demands to be assessed. The question of how soils will continue to support coastal structures encouraged by the interest of developers to meet demand for panoramic views of coastal beaches. While the impact of possible instability on coastal condominiums demands to be studied in medium-sized structures, the dangers of ground instability created by increased emendation of beach sand, saltwater incursion, and possible subsidence due to sinkholes. All increase the vulnerabilities of the ecotonal coastline, but only by foregrounding the increased penetration of saltwater, salt air, and soil stability in the increasingly anthropogenic coast can the nature of how ecotonal intersection of land and augment the risks buildings face.

Facing Extreme Climate Upon Re-Entering the Paris Climate Accords

In an age it is disturbingly familiar for news maps to place us on tenterhooks by grabbing our attention, the existential urgency of the blanket of the continent with icy arctic air was no exception. But if the images of sudden entrance of frigid air shocked most states in the union and lower forty eight, the farther one collapsed the week of freezing cold, the more one could see a clarion call for the re-entrance into the Paris Accords. It was as if NOAA visualizers of meteorological disturbances, newly liberated, were free to show the dangerous consequences of the tippy polar vortex and uncertain weather in an era of extreme climate change. Bright color ramps foregrounded falling temps in rich magenta or icy blue were almost off the charts, from the uppermost end of the spectrum in their duration–below–or in the low temperatures that were advanced–in maps that push the boundaries of expectations with urgency.

As maps of the hours the nation was plunged into subzero trace a purple cold front advanced all the way into the deep south as it spread across the continent from up north, the continent shivered under the icy blues over the mid-February cold spell. As we re-enter global climate accords, and consider what global accords can come to terms with climate change, it seems opportune to consider the alerts that remotely sensed mappings of our changing global climate chart. The chromatic intensity jarred with the familiar spectrum of meteorological maps to shock the viewer: the map challenged any reader to try to place the arrival of cold air and hours below freezing in a frame of reference, to dismiss the incursion of icy air up to the US-Mexico border as an irregular occurrence, more than a harbinger of premonition of the cascading effects of extreme weather, let alone a warning of the limits of our national infrastructure to adjust to it.

If the focus of the NOAA maps of the National Weather Service fulfilled their mandate by focussing on the territoriality of the United States, these images and the news maps made of them communicated a sense of national violation, if not of the injustice of the incursion of such unexpected freezing temperatures and Arctic air, as if it were an unplanned invasion of the lifestyle, expectations, energy policy, and even of the electric grid of the United States, oddly affirming the American exceptionalism of the United States’ territory and climate, as if the meteorological maps that confounded predictions were not a global climactic change.

And in the maps of the fall in national temperatures, as in the header to this post, the news that the nation witnessed a frozen core spread south to the southwest, almost reaching the border, seemed to shift our eyes from a border that was mapped and remapped as permeable to migration, to a map of unpreparedness for climate change, almost echoing the systemic denial of climate change that has been a virtual pillar of the Trump Presidency on the eve when Donald Trump had permanently relocated to Mar a Lago, one of the last areas of the nation that was not hit by the subzero temperature anomalies that spread across north Texas, Oklahoma, Kansas, Missouri, New Mexico and Iowa, plunging the many states we though of as “red” during the past election an icy deep blue interior in mid-February down to the Gulf Coast–as if the colors were a national crisis not of our own making for a nation that had obsequiously voted Republican, withdrawn from the Paris Accords, and allowed the warmer temperatures to be located only in the state where Donald Trump was now residing in Mar a Lago.

–that , as the week of arctic air’s arrival wore on, the newspaper of record glossed by a color ramp of low temperatures few residents southern states expected to be plunged into subzero surroundings. The color ramp they chose to chart how gelid air poured set off a cascade of events and disasters nicely demonstrated cascading effects of climate change on the nation, as the shock of low temperatures sucked the national attention away from the border, and begged one to come to terms with the challenge of climate emergencies in global terms. The frozen core of the nation was a wake-up call, re-re-rendering the familiar Red, White and Blue in faded out terms of the distorted levels of cold the nation currently confronts–the increased escalation of which we are projected to face.

Lowest Temperatures in Country, February 12-16/New York Times, February 18, 2021

The entrance of gelid air from a polar vortex poured across much of the midwest in unrelenting fashion. Plunging subzero temps hit the Texas coast that overloaded electric grids and shocked weather maps that seemed out of whack even for mid-February, as even the sunbelt of the southwest turned gelid cold as subzero temperatures arrived over a week, plunging the arctic neckline down into Texas, and almost across the southwestern border.

Losing Beaches, Losing Places

We have long considered man’s impact on the world, but are only starting to be able to chart the vastness of the scope of anthropogenic change. And wen it comes to the contraction of shores and beaches that has been forecast in current climate scenarios, the oldest of human environments, the shoreline and coast, seems in danger of drastic reduction at a scale we have rarely considered. The shifting littoral landscapse of the world have ben long neglected, if they are turned to each Earth Day for coastal cleanups and have been the site of intense preoccupations as a result of sea-level rise, as we have protected much of our national seashore.

National Seashore (National Park Service)

But the prospect of an accelerated global erosion of coastal landscapes, and the loss of beaches, have only begun to be processed as triggering cascading consequences from disturbing ecological niches and coastal economies to the human relation to the natural world–a new relation to global ecology that we may well lack the vocabulary and structures to map on adequate scale to process, let alone discuss.

But the mapping of coastal retreat that is projected for the coming century charts the magnitude of the scale of impact of human-created modification of a global environment in NOAA’s Fluid Dynamics Project calls for a broader reckoning of the impact on the global environment that stands to be created by coastal retreat akin to a global pandemic like SARS-CoV-2, and a remapping of the global shorelines that we have a very limited chance to come to terms with in any active context; terms like East and West don’t work in a climate catastrophe that does not differentiate not only nation states but that we lack the narrative categories to come to terms with in terms of economic inequalities, but suggest a crisis of global proportions that contrast with the delicate organization of space on shorelines near our home in their brute redrawing of the increasingly impermanent sandy shore projected for 2100, according to a rather modest climate change scenario.

The discovery of margin of the shoreline in the middle of the twentieth century as a privileged site of intense biodiversity risks obliteration as a particularly fragile ecosystem. Yet the shoreline habitat is now a site of unprecedented vulnerability. (The same stretch of sensitive shoreline habitat was quickly closed to comply with shelter-at-place directive, given the range of urban residents who drove to flood its trails, beaches, and shoreline as a way to find balance, many standing transfixed before the waves in a particularly stressful time, seeking purchase on a moment few could really grasp.)

McClures Beach, Inverness CA

The seashore seemed a natural place of reflection. But it was hard to imagine the sensitivity of these littoral lands. While the national seashore at Point Reyes is a unique preserved coastal environment, where eroding cliffs meet sands along broad strips of beach whose low grade offers habitat to coastal birds, grasses, and shellfish, in a meeting point of fresh and salt water, the beauty of the coast seemed a perfect refuge in a time of disorientation.

This blog has long discussed the specter of anthropogenic change, but in the panic of COVID-19, it seemed clear that we lack the mode to talk about the scale, continuities, and complexity at which such world-changing processes will occur. The future loss of shores would be quite difficult to imagine, even if one stares at the remote sensing maps that predict the effects of sea-level rise.. So many had voyaged to the shores as if by instinct during the COVID-19 coronavirus outbreak in 2020, from Long Island to Marin, to the extent of disturbing many coastal residents, who read searching for break from anxiety by acts of coastal distancing as an unwelcome promotion of the danger of importing viral spread.

In England and elsewhere, many departed from the city, in search of a new environment, by traveling to the coasts–where they were greeted, similarly, by protests by those who saw their arrival as a harbinger of infection. Many public beaches, concerned about close contact, have outright closed, as coastal communities do their best to dissuade visitors seeking to escape infection in Hawaii, Moab, Alabama, North Carolina or the Gulf Coast–in ways that cut us off from the shore as a place of reflection and rumination.

If undue media attention may be directed to bemoaning college students on Florida Spring Break, we must remember that Florida’s Governor, Ron DeSantis, ostensibly encharged with securing the state’s well-being and public welfare, stubbornly insisted on keeping beaches open in the state the shore until Easter, to allow “students to party” on Miami Beach, Fort Lauderdale, Clearwater Beach, and other “hotspots” of pleasure into hot spots of viral infection: DeSantis, never one to stop claiming higher ground, hypocritically or not, only turned his wrath on the partiers after facing a lawsuit from the state Attorney General, and even as communities closed beaches, refused to shutter state beaches to limit the spread of the Coronavirus that were a vital parts of the state’s economy–reluctant to close them until local municipalities intervened.

John Raedle/Getty Images

Shifting the blame to foreign travelers–and insisting on self-quarantining visitors from New York state or New Jersey–he sought to keep them open for business, by casting them as more vital than viral. DeSantis refused to accept the national scope of the problem, defending an economy that depended on tourism, elevating the economy over national health–and keeping them open a week after the closure of Disney World, after trying to keep a “six feet distance rule” to “stop large crowds from congregating,” as if the crowding was an issue, more than human proximity and contact–and refusing to take leadership on the issue by “deferring” to local government and causing confusion.

As fhe Florida Governor reflected on the large number of elders in the state population, and their potential hindering of his own chances for re-election, it seems, did he alter his stance entirely, and beg the President to declare a national emergency, as the spread of the virus led to thousands of layoffs, with all non-essential businesses closed in coastal communities, as De Santis issued a state of emergency March 9, 2020.

Initial Florida Sites of Coronavirus Outbreaks of COVID-19 Infections/March 9, 2020

Meanwhile the COVID-19 data timeline by mid-March had spread across Central Florida, with cases of infection clustering on the shores. While the map that sizes the isolated pathogen as its symbol of COVID spread seems freakish, the telling newspaper graphic captures well the problem of coming to terms with the transmission of infections along the beach–superimposing the specter of an overlay of the COVID-19 pathogen as if colonizing or as blossoming along Floridian shores.

Orlando Sentinel

The abandonment of the closed Miami Beach–one of several citie that refused to keep its beaches open, as infection spread, as they knew what was really best for them–seemed to confirm the shore’s status as a natural site of reflection. The scope of projected reconfiguration of future shorelines would effect a deep change in the human relation to the shoreline, as much as the shoreline as a site of shelter and habitat.

For environmental geographer Clarence Glacken, the “traces on the Rhodian shore” were signs of civilization and the human modification of the environment that were fundamental to historical processes of change. The reference of the title of his survey of the modification of land through the industrial revolution took its reference point as antiquity–the image of the philosopher taking geometric figures drawn on the shores of Rhodes where he was shipwrecked as evidence of human habitation. The anecdote was prized by Vitruvius as evidence of the ability of geometry to frame the environment, and respond to it; Glacken took the image of the shores as a leitmotif for a magisterial survey of relations to the natural world that we now observe expanded and refracted in the remote sensing that tracks the broad impact of how industrialization has inscribed human relations to the environment far beyond Glacken’s four on the environmental influences on human history and man’s remaking of the environment. And the problem of the continued access to shores, and future of the shores, makes us go back to some of the early work of Glacken to recover its new relevance, if only because of our failure of models to come to terms with such massive anthropogenic change.

Saturated Shores in Southeastern Texas

There is almost no trace of the human, or of the extreme overurbanization of the Texas coast, in most of the maps that were created of the extreme flooding and intense winter rains that hit Galveston and Houston TX with the windfall of Hurricane Harvey.  While maps serve to orient humans to the world–and orient us to human processes and events in a “human world,” as J.B. Harley and David Woodward put it, the confused nature of relations between the human and natural world, is increasingly in danger of being mipmapped.  Data visualizations of extreme weather that erase the modification of coastal environments provide a particularly challenging means of orientation, as news maps are suspended between registering the shock of actual events–and trying to contain the natural emergencies that events of extreme weather create–and the demand for graphics that register natural calamities and the ethics of showing such calamities as “natural”–or even what the category of the natural is in coastal regions that so heavily modified to modify actual weather events.

The ethics of orienting viewers to the rainfall levels that fell in Houston after the landfall Hurricane Harvey Part of the huge difficulties lies in adequately orienting viewers in ways that register a changing natural world–how we are mapping rainfall, for example, or the approach of hurricanes, or are rather mapping the new relation of rain to built surfaces and landcover change that lack permeability for water, facilitating flooding by storms whose potency is changed by the greater atmospheric content of a warming Gulf of Mexico, which the ground cover of Houston, Galveston, and the Texas shore are less able to absorb and return to the Gulf. The area is, itself, something of an epicenter of the increased number of hemispheric tropical cyclones–which demand warm water temperatures above 80 80°F / 27°C and a cooling atmosphere and low wind shear–often led to the Gulf coast.

NASA Earth Observatory/Tropical Cyclones through 2006

–those that come ashore at Galveston hit a seashore that is eminently unprepared to accommodate an influx of water that the paved surface has rendered all but impermeable. If the problem of global cyclones that can become hurricanes is truly global–

NASA Earth Observatory/150 years of Tropical Cyclones

–the intersection between cyclones and areas of paved ground cover is problematic to the southwestern states, and most of all to Texas, Louisiana, and Florida, where water absorption has been anthropogenically reduced in recent decades. At the same time, few other areas of the inhabited world are so widely “tracked” as the destination of tropical cyclone formation..

NWS JetStream Online School)

The problem is partly evident in the choice of new color ramps that transcend the rainbow spectrum of measuring the intensity of rainfall in the recent arrival or ground fall of Hurricane Harvey, which condenses the great difficulty of using old cartographical categories and conventions in order to capture or communicate increasingly extreme weather conditions. in an era of climate change.  But the cartographic problem goes farther:  for it lies in the difficulty of registering the changes in relations f how rain dropped meets the ground, mapping relations between complex processes of warming and atmospheric warmth that lead to greater humidity across the gulf region to ground cover permeability that leaves regions increasingly exposed to flooding.

The relentless logic of data visualizations based on and deriving primarily from remote sensing are striking for rendering less of a human world than the threat of allegedly “natural” processes to that world.  Perhaps because of the recent season of extreme weather we have experienced, weather maps may be among the most widely consulted visualizations in our over-mediated world, if they were already widely viewed as the essential forms of orientation.  But the pointillist logic of weather maps may fail to orient us well to extreme events as the hurricane that dumped a huge amount of water on overbuilt areas to include the human–or the human world–seem a tacit denial of the role of humans in the complex phenemona of global warming that have, with the warming waters of the Gulf of Mexico and ever-increasing ozone over much of the overbuilt southeastern Texas shore, created a perfect storm for their arrival.

This failure to include this role haunts the limited content of the weather map; including the role of humans in maps of extreme weather events indeed remains among the most important challenges of weather maps and data visualization, with the human experience of the disasters we still call natural.  And although the subject is daunting, in the spirit of this blog, we will both look at the communicative dilemmas and difficulties of eye-catching color ramps and their deceptiveness, and poetic difficulties of orienting oneself to shores.  For as the disaster of Harvey is depressing, it compels raising questions of the orientation to the shifting shore, around the national epicenter of Galveston, where the landfall of Hurricane Harvey focussed our attention on August 27, 2017–

–and the meaning of place in an saturated shoreline, where the sea is somehow part of the land, and the land-sea divide blurs with a specificity that seems as if it may well be increasingly true in an approaching era of climate change.  And as we depend on the ready generation of maps based on remote sensing whose relentless logic is based on points, we risk looking sight of the role of place in determining the relations of rainfall to shoreline in maps of coastal flooding that remove remote observations from the built environment that flooding so drastically changes, challenges and affects, in ways that may elide specificities of place.

At a time when we are having and will be destined to have increased problems in orienting ourselves to our shores through digital maps of rainfall, the unclear shorelines of Galveston sent me to the bearings that a poet of an earlier age took her bearings on the mapped shorelines of the place where she had been born, and how she was struck by a bathymetric map to gauge her personal relation to place, and saw place in how the changing shoreline of the northern Atlantic were mapped in the maritimes, in a retrograde form of print mapping in a time of war.  For the way the mapped shore became a means by which Elizabeth Bishop gained bearings on shores through a printed map of coastal bathymetry to access the spatiality of the shore–how “land lies in water” and the blurred relation of land and water that the bathymetric map charts–in an age when the materiality of the map was changing, with the introduction of aerial composite maps from the early 1930s, as the rise of aerial composite maps removed the hand of the mapmaker from the map in an early instance of remote sensing–

–in a medium of aerial photography that focussed on land to the exclusion of water, and that all but erased the relation between water and shore just a few years after Bishop quickly wrote her poem in Christmas 1935 about coastal “edges” of land and sea.  Ryker, who developed techniques of aerial photography used in the mapping of the shores of Puerto Rico for the Fairchild Aerial Camera Company, as well as photographs of the devastating Berkeley Fire of 1923, went into business in 1938–the year of his map–as a map publisher, with a patent for the stereoscope used to interpret aerial imagery,  and must have performed the massively detailed mapping of San Francisco in one hundred and sixty for images taken from airplanes from 1937-38 as a sort of calling card, soon after Bishop wrote her poem, before manufacturing a range of stereoscopes of pocket and desktop versions for military ends that were widely used in World War II by the US Army.

Before war broke out, but in ways that anticipated the coming war, the printed bathymetric map must have resonated as a new reflection on the impersonality of the aerial view; Bishop was suddenly struck when she encountered the materiality of a print map on Christmas 1938 as the art of cartography was already changing, responding to the drawn map under glass of the Atlantic as a way to recuperate the personal impact of place.  Her poem powerfully examined the logic of drawn maps utterly absent from the digitized space of rainfall maps of a flood plain, deriving from data at the cost of human inhabitation of place–and in envisioning data to come to terms with the catastrophic event of flooding distancing or removing the craft of mapmaking from the observer in dangerously deceptive ways.  And so after wrestling with the problems of cartographic representation using remote sensing, while recognizing the value of these readily produced maps of rainfall and the disasters they create,

1.  For weather maps are also among the most misleading points to orient oneself to global warming and climate change, as they privilege the individual moment, removed from a broader context of long-term change or the human alteration of landscape.  They provide endless fascination by synthesizing an encapsulated view of weather conditions, but also  suggest a confounding form of media to orient audiences to long-term change or to the cascading relations of the complex phenomenon of climate change and our relation to the environment, as they privilege a moment in isolation from any broader context, and a sense of nature removed from either landscape modification or human intervention in the environment, in an area were atmospheric warming has shifted sea-surface temperatures.  The effects on the coast is presented in data visualizations that trace the hurricane’s “impact” as if its arrival were quite isolated from external events, and from the effects of human habitations on the coast.  The image of extreme flooding is recorded as a layer atop a map, removing the catastrophic effects of the flooding from the overpaved land of the megacities of southeastern Texas, and the rapid paving over of local landcover of its shores.

.

Such visualizations preserve a clear line between land and sea, but treat the arrival of the rains on land as isolated from the Consuming such events of global warming in color-spectrum maps.  The data of rainfall translate data into somewhat goofy designs represents a deep alienation from the environment, distancing viewers in dangerous ways from the very complexity of global warming that Gulf coast states encountered.

Such data visualizations seem dangerously removed notion of how we have changed our own environment, by describing a notion of “nature” that is immediately legible, as if it were removed from any human trace or of the impact of modification of the land, and by imaging events in isolation from one another–often showing a background in terrain view as if it has no relation to the events that the map describes.  Although weather maps and AccuWeather forecasts are sources of continual fascination, and indeed orientation, they are are also among the most confounding media to orient viewers to the world’s rapidly changing climate–and perhaps among the most compromised.  For they imply a remove of the viewer from space-and from the man-made nature of the environment or the effects of human activity form the weather systems whose changes we increasingly register.  By reifying weather data as a record of an actuality removed from human presence at one place in time, they present a status quo which it is necessary to try to peel off layers, and excavate a deeper dynamic, and indeed excavate the effects of human presence in the landscape or geography that is shown in the map.  We are drawn to tracking and interpret visualizations of data from satellite feeds in such weather maps–or by what is known as “remote sensing,” placed at an increased remove from the human habitation of a region, and indeed in a dangerously disembodied manner.

Visualizations resulting from remote observation demand taken as a starting point to be related to from the human remaking of a region’s landscape that has often increasingly left many sites increasingly vulnerable to climate change.  But the abstract rendering of their data in isolation from a global picture–or on the ground knowledge of place–may render them quite critically incomplete.  The remove of such maps may even suggest a deep sense of alienation form the environment, so removed is the content of the data visualization form human presence, and perhaps from any sense of the ability to change weather-related events, or perceive the devastating nature of their effects on human inhabitants:   their stories are about weather, removed form human lives, as they create realities that gain their own identity in images, separate from a man-made world, at a time when weather increasingly intersects with and is changed by human presence.  While throwing into relief the areas hit by flooding near to the southeastern Texas shore at multiple scales based on highly accurate geospatial data, much of which is able to be put to useful humanitarian uses–

–the reduction of floods to data points creates a distorted image of space renders their occurrence distant from the perspective of folks on the ground, and places their content at a considerable remove from the complex causality of a warming Gulf of Mexico, or the problems of flood drainage by which Galveston and Houston were beset.  Indeed, the multiple images of that report rainfall as an overlay in a rainbow spectrum, at a remove from the reasons for Houston’s vulnerability to flooding and the limits the region faces of flood control, in broadcast Accuweather images of total rainfall in inches advance a metric that conceals the cognitive remove from the dangers of flooding, ora human relation to the landscape that the hurricane so catastrophically affected.  Can we peel under the layers of the data visualization, and create better images that appreciate the human level on which the landscape stands to be devastated by hurricane rains, as much as tracking the intensity of the growth of rainfall over time?

Such layers of green, meant to suggest the intensity of rainfall that fell over land, reveal the concentration of water in areas closes to the Gulf of Mexico.  Even the most precise geographical records of the dangers of flooding in the floodplain of southeastern Texas with little reference to the historical modification of the region by inhabitants–

–and conceal the extent to which the landscape’s limited ground cover permeability has left the region far more susceptible to flooding, and elevated the risks of the emergency.  The problem of reading any signs of human presence into these “images” of precipitation provoke problems of disentangling remote sensing data from knowledge of the region’s recent urban growth and the consequent shift in local landcover.

The perspective of our relation to these events is often as fleeting and as existential as they flood us with data, which we viewers have little perspective or tools to process fully.  The onrush of recent remote sensing maps batter us with an array of data, so much as to lead many to throw up their hands at their coherence.  Even as we are  still trying to calculate the intensity of damages in Puerto Rico–where electricity is so slowly returning that even even after four months, almost a third of its 1.5 million electricity customers still lack power–and the cost of fires in southern California.  We look at maps, hoping to piece together evidence of extensive collateral damage of global warming.  Yet we’ve still to come to terms with the intensity of rainstorms that hit southeastern Texas–deluging the coast with rainfall surpassing the standard meteorological chromatic scale that so misleadingly seems to offer a transparent record of the catastrophe, but omits and masks the experiences of people on the ground, digesting swaths of remotely sensed data that take the place of their perception and experience, and offering little critical perspective on the hurricane’s origin.

The rapidity with which rain challenged ground cover permeability provides both a challenge for mapping as a symptom of global warming and landscape modification:   the mapping of “natural” levels of rainfall blurs the pressing problem of how shifting landcover has created an impermeability to heightened rains, and indeed how the new patterns of habitation challenge the ability of the coast of the Gulf of Mexico to absorb the prospect of increased rain in the face of decreasing groundcover permeability, and the extreme modification of the coastline that increasingly impeded run-off to the Gulf.

2.  Across much of southeastern Texas, a region whose growth was fed by the hopes of employment in extractive industries, real estate demand and over-paving have unfortunately intersected with extreme weather in southeastern Texas in ways which dat visualizations have had trouble exposing, but which raise a curtain on the coming crises of a failure of ability to accommodate increased levels of rainfall  If the lack of precedent for the intense rainfall in Galveston Bay generated debate about introducing a new color that went beyond the rainbow scale employed in weather charts, what seemed a problem of the cartographic color-spectrum suggested a problem of governability and indeed government response to extreme weather conditions.  How to register the dangers of rainfall that goes of the scale or standards of measurement?

One must consider how to orient viewers to the intensity of consequent flooding, and to its consequences and better prepare ourselves for the arrival of deluging rains without falling back on the over-freighted metaphor of rains of biblical scope.  How many more hurricanes of increasing intensity can continue to pound the shores, by whipping precipitation from increasingly warming waters and humid air?  The cumulative pounding of tropical cyclones in the Gulf stands to create a significantly larger proportion of lands lying underwater–temporarily submerged lands–with radically reduced possibilities of drainage, as hurricanes carry increased amounts of evaporated water from the humid air of the warming gulf across its increasingly overbuilt shores. in ways that have changed how the many tropical cyclones that have crossed the land-sea threshold since NOAA began tracking their transit (in 1851) poses a new threat to the southeastern coast of Texas, and will force us to map the shifting relation between land and water not only in terms of the arrival of hurricanes, or cyclonic storms–

–but the ability of an increasingly overbuilt landscape to lie underwater as the quantity of the Gulf coast rainfall stands to grow, overwhelming the overbuilt nature of the coast.

Most maps that chart the arrival and impact of hurricanes seem a form of climate denial, as much as they account for climate change, locating the hurricanes as aggressive forces outside the climate, against a said backdrop of blue seas, as if they  are the disconnect.  Months after the hurricane season ended, the damage for hurricanes caused have hardly been assessed in what has been one of the most costly and greatest storm damage since 1980 in the United States,–including the year of Hurricane Katrina–we have only begun to sense the damage of extreme weather stands to bring to the national infrastructure.  The comparison to the costs of storm damage in previous years were not even close.

But distracted by the immediacy of data visualizations, and impressed by the urgency of the immediate, we risk being increasingly unable to synthesize the broader patterns of increased sea surface temperatures and hurricane generations, or the relations between extremely destructive weather events, overwhelmed by the excessive destruction of each, and distracted from raising questions about the extremely poor preparation of most overbuilt regions for their arrival, and indeed the extent to which regional over-building that did not take the possibility of extreme weather into account–paving large areas without adequate drainage structures or any areas of arable land–left inhabitants more vulnerable to intense rains.  For in expanding the image of the city without bounds, elasticity, or margins for sea-level rise, the increasingly brittle cityscapes of Galveston and much of the southeastern Texas shoreline were left incredibly unprepared for the arrival of hurricanes or intense rains.  Despite the buzz of an increased density of hurricanes to have hit the region,

1851_2013_mjrhurr2

the questions of how to absorb hurricanes of the future, and to absorb the increased probability of rainfall from hurricanes in the Gulf of Mexico and its shores, suggests questions of risk, danger, and preparation that we have no ability to map.  What, indeed, occurs, as hurricanes themselves destroy the very means of transmitting on the ground information and sensing weather, and we rely exclusively on remote sensing?

To characterize or bracket these phenomena as “natural” is, of course, to overlook complex interaction between extreme weather patterns and our increasingly overbuilt environments that have both transformed the nature of the Southeastern Texas coast and have made the region both an area of huge economic growth over time, and have paved over much of the floodplain–as well as elevated the potential risks that are associated with coastal flooding in the Gulf Coast.  To be sure, any discussion of the Gulf of Mexico must begin from the increasingly unclear nature of much of our infrastructure across land and sea, evident in the range of pipelines of gas and oil that snake along a once more clearly defined shore charted by ProPublica in 2012, revealed the scope of the manmade environment that has both changed the relation of the coastal communities to the Gulf of Mexico, and has been such a huge spur to ground cover change.

The expansive armature of lines that snake from the region across the nation–

-and whose tangle of oil pipelines that extend from the very site of Galveston to the Louisiana coast is almost unable to be defined as “offshore” save as a fiction, so highly constructed is much of the national waters in submerged lands in the Gulf of Mexico–

They indeed seem something of an extension of the land, and a redefinition of the shore, and reveal a huge investment of the offshore extractive industries that stand to change much of the risk that hurricanes pose to the region, as well as the complex relation of our energy industries to the warming seas.  Yet weather maps, ostensibly made for the public good, rarely reveal the overbuilt nature of these submerged lands or of the Gulf’s waters.

Despite the dangers that such an extensive network of hazardous liquid lines along the Gulf of Mexico, the confusion between mapping a defined line between land and water, and visualizing relations of extreme weather disturbances as hurricanes in the Gulf of Mexico and local infrastructure haunts the extremely thin nature of the sort of data visualizations that are generated about the dangers of hurricanes and their landfall in the region.  For all too often, they presume a stable land/sea divide, removed from the experience of inhabitants of the region and how we have remade the shore.

3.  How can we better integrate both a human perspective on weather changes, and the role of human-caused conditions in maps of extreme weather?  How can we do better by going beneath the data visualizations of record-breaking rainfall, to map the human impact of such storms?  How could we do better to chart the infrastructural stresses and the extent to which we are ill-prepared for such extreme weather systems whose impact multiplies because of the increased impermeability of the land, unable to absorb excessive rainfall, and beds of lakes and reservoirs that cannot accommodate increased accumulation of rainfall that  stand to become the new normal?  The current spate of news maps that provoke panic by visualizing the extremes of individual cases may only inspire a sort of data vis-induced ADD, distracting from infrastructural inadequacies to the effects of global warming–and leaving us at a loss to guarantee the best structures of governability and environmental readiness.

Indeed, the absence of accurately mapping the impact and relation between landcover, storm intensity, rainfall, flooding, and drainage abilities increases the dangers of lack of good governance.  There need not be any need for a reminder of how quickly inadequate mapping of coastal disasters turns into an emblem of bad governance.  There is the danger that, overwhelmed by the existential relation to each storm, we fail to put them together with one another; compelled to follow patterns of extreme weather, we risk being distracted from not only the costs but the human-generated nature of such shifts in seasons between extremes of hot and cold.  For as we focus on each event, we fail to integrate a more persuasive image of how rising temperatures stand to create an ever-shifting relation between water and land.

Provoked by the rhetoric of emergency, we may need to learn to distance ourselves better from the aerial views that synthesize intense precipitation, tally hurricane impacts, or snowfall levels, and view them less as individual “strikes” or events and better orient ourselves to a broader picture which put us in a less existential relation to extreme weather.

We surely need to establish distance to process syntheses of data in staggering aerial views on cloud swirl, intense precipitation, and snowfall, and work to peel back their striking colors and bright shades of rainbow spectra, to force ourselves to focus not only on their human costs, or their costs of human life, but their relation to a warming planet, and the role of extreme of weather in a rapidly changing global climate, as much as track the “direct strikes” of hurricanes of individual names, as if they were marauders of our shores:  their creation is as much tied to the changing nature of our shores and warming sea-surface temperatures, and in trying to create a striking visualization, we deprive ourselves from detecting broader patterns offering better purchase on weather changes.

The Weather Channel

If patterns of weather maps epitomized by Accuweather forecast and projections suggest an exhilaratingly Apollonian view on global and regional weather patterns, they also  shift attention form a broader human perspective in quite deeply pernicious ways.  Such maps provided the only format for grasping the impact of what happened as the hurricane made landfall, but provided little sense of the scale of inundations that shifted, blurred and threatened the coast of the Gulf of Mexico.  They provide a format for viewing floods that are disjoined from victims, and seem to naturalize the quite unnatural occurrence of extreme weather systems.  Given the huge interest in grasping the transformation of Hurricane Harvey from a tropical storm to a Category Four hurricane, and the huge impact a spate of Category Four hurricanes have created in the Gulf of Mexico, it’s no surprise that the adequacy of the maps of Hurricane Harvey have been interrogated as hieroglyphs or runes of a huge weather change:  we sift through them for a human story which often left opaque behind bright neon overlays, whose intensity offer only an inkling of a personal perspective of the space or scale of their destruction on the ground:  while data maps provide a snapshot of the intensity of rain-levels or wind strength at specific sites, it is difficult if important to remember that their concentration on sites provide a limited picture of causation or complexity.

All too often, such maps fail to offer an adequately coherent image of disasters and their consequences, and indeed to parse the human contributions to their occurrence.  This post might be defined into multiple subsections.  The first actions suggest the problems of mapping hurricanes in the Gulf of Mexico in relation to flooding in data visualizations of the weather and the overbuilt region; the middle of the post turns to an earlier poetic model for considering the relation between land and sea that visualizations all too easily obscure, and the meaning that the poet Elizabeth Bishop found in viewing relations between land and sea in a printed map of the Atlantic; after returning to the question of the overbuilt shore compounds problems of visualizing the Texas coast, the final section, perhaps its most provocative, returns to Bishop’s reading of a map of the Atlantic coast.

What such new weather maps would look like is a huge concern.  Indeed, as we depend on weather maps to orient us to place ourselves in the inter-relations of climate change, sea-level, surface temperatures, and rain, whether maps cease to orient us to place, but when best constructed help to describe the changing texture of weather patterns in ways that can help familiarize us not only to weather conditions, but needed responses to climate change.  For  three months after the hurricanes of the Gulf of Mexico caused such destruction and panic on the ground, it is striking not only that few funds have arrived to cover costs of rebuilding or insurance claims, but the judgement or understanding of the chances for future flooding have almost left our radar–perhaps pushed rightly aside by the firestorms of northern and southern California, but in ways that troublingly seem to forget to assess or fail to assess the extent of floods and groundwater impermeability  along the Texas and Louisiana coast.  The problems that preparation for future coastal hurricanes off the Gulf of Mexico raise problems of hurricane control and disaster response that seem linked to problems of mapping their arrival–amd framing the response to the increasing rains that are dumped along the entire Gulf Coast.

Indeed, the chromatic foregrounding of place in such rainbow color ramps based on GPS obscure other maps.   Satellite data of rainfall are removed from local conditions, and serve to help erase complex relations between land and water or the experience of flooding on the ground–by suggesting a clear border between land and sea, and indeed mapping the Gulf of Mexico as a surface as if it were unrelated to the increased flooding around Houston, in maps prepared from satellite imagery, despite the uneasy echoes of anthropogenic causes for the arrival of ten hurricanes in ten weeks, in ways that suggest how warming waters contributed to the extreme inundation of the Gulf Coast.  Despite NOAA  predictions of a 45% likelihood of ‘above-normal’ activity for the 2017 Atlantic hurricane season, with, a 70% likelihood of storms that could transform into hurricanes, the images of inundated lands seem both apocalyptic and carefully removed from the anthropogenic changes either to the ocean or land that intensified their occurrence so dramatically on the ground.

Is it possible to recuperate the loss of individual experience in such data maps, or at least acknowledge their limitations as records of the complexity of a changing climate and the consequences of more frequent storm surges and such inundations of rainfall?  As we seek better to understand the disaster relief efforts through real-time maps of effects of Hurricane Harvey as it moved inland from the Gulf of Mexico, shifting from Category 4 Hurricane from a tropical storm, we tried to grasp levels of rainfall that spun out of 115-mile-an-hour winds across southeastern Texas that damaged crops, flooded fields, ruined houses, and submerged cars, we scan stories in hope of clues to assess our position in relation to increasingly dangerous weather systems whose occurrence they may well forebode.  At a time of increased attention to extreme weather has long developed, the gross negligence of climate change denial is increasingly evident:  it recalls the earlier denial of any relation between hurricanes and climate change, when increased hurricanes were cast as “the cycle of nature,” rather than as consequences whose effects have in fact been broadly intensified by human activity.

Current attempts to map the toll of record-smashing hurricanes focused almost exclusively on point-based data view rainstorms largely as land-based records; even as they intend to monitor the effects of Harvey’s landfall by microwave censors, they risk seeming to isolate real-time rainfall levels from the mechanics warmer air and sea-surface temperatures which result from human-caused global warming, not relating increased storm surges or inundations to achanges in coastal environments or climate change.  To render such changes as natural–or only land-based–is irresponsible in an age of reckless levels of climate denial.  Indeed, faced by the proliferation of data visualizations, part of the journalistic difficulty or quandary is to integrate humanistic or individual perspectives on the arrival of storms, rendered in stark colors in the increasingly curtailed ecosystems of newsrooms which seek simplified visualizations of satellite data on the disaster, which fail to note the human contributions to the travails that are often reserved for photographs, which increasingly afford opportunities of disaster tourism in the news, emphasizing the spectator’s position before disasters, by images that underscore the difficulties in processing or interpreting the proliferation of data from MODIS satellite feeds:  we can show the ability to measure the arrival of torrential rains, but in offering few legends, save the date and scale, but offering few keys o interpret the scale of the disaster.

The looming portent of human-made climate change, however, underlies the poor predictions that NOAA offered of perhaps 2-4 major hurricanes this Spring, and the lack of a new director for NOAA–on which local and state agencies depend to monitor the nations shores and fisheries–suggested the, from June to September, which left states on their own to make decisions and plan for disaster mitigation programs and better flood maps.  (The danger of appointing a newly nominated director, Barry Myers, who is a strong supporter of the privitization of weather maps and an executive at the private Accuweather mapping service, suggests the difficulty of determining the public-private divide in an era of neoliberalism, and a free market of weather maps that were once seen as central to national security and standards of safety.)   There are two hidden scales on which we read these opaque maps of global warming and globalization and local inundation are triply frustrating.   For all the precision and data richness of such point-maps of largely land-based rainfall, local temperature, or flooding, the biases of such instantaneous measurements seem to fit our current governing atmosphere of climate change denial, and dangerous in erasing how such storms are informed by long-term consequences of man-made climate change.  (As the mapping tools of coastal weather seem destined to change, what sort of change in direction for NOAA coastal maps do we want:  the appointment suggests the terrifying possibility of a return to the Bush-era proposal nominee Myers supported that prohibiting the agency from producing any maps already available in the private sector then threatened federal weather lines to go dark–lest they literally compete with ad-supported websites private providers–and shift federal information offline?)

For making moves toward the future readability of weather maps may well be at stake in critically important ways.  The 2005 proposal that Myers backed would have eliminated the National Weather Service, even while exempting those forecasts needed to preserve “life and property,” would in essence have returned the weather services to a pre-internet era, even as the most active hurricane season including a record breaking fifteen hurricanes and twenty-eight storms began in the gulf coast, including the infamous hurricane Katrina.  The proposed bill would have prevented NOAA from posting open data, and not only readily available to researchers and policymakers, in ad-free formats, free of popup screens, but allow them to make their own maps on the fly–ending good practices of posting climate data would work quite dangersously to prevent development of tools of data visualization outside commercial models of rendering storms and hurricanes as if environmentally isolated.

A deeper problem of providing such limited weather maps of tropical storms may be the subtexts about the relation of human causes to weather they convey, and the absence of a greater narrative of the transformation of a global ecology or of the ecology of the Gulf Coast.  The curtailed images of “nature” they present by symbolizing rains, winds, floods, or submerged regions in appealing hues as natural–raise questions of the odd simplicity of the absent storylines:  cheery colors erase or bracket complex questions of climate change, the human contribution to extreme weather events, or the human experience of suffering on the ground:  Rita, Cindy, Katrina, Dennis, and Wilma seem not part of the environment, epiphenomenal interlopers moving across a static deep blue sea, in an apparent dumbing down of the mechanics of hurricane or storm formation in a rainbow spectrum removed from a human-made environment.
