A Spatial History of Sleep

[Image: Fish preserved in the eternal ocean of a closed jar at the American Museum of Natural History; old Instagram by Geoff Manaugh].

Although this is a classic example of something I am totally unqualified to talk about, a recent report over at ScienceNews caught my eye, about the spatial origins of REM sleep.

In a nutshell, the paper suggests that “sleep may have originated underwater 450 million years ago,” which is apparently when “the cells that kick off REM sleep” first evolved in fish. “During REM or paradoxical sleep,” we read, “the brain lights up with activity almost like it’s awake. But the muscles are paralyzed (except for rapid twitching of the eyes) and the heart beats erratically.”

Dreaming, it’s as if ancient fish learned to pass into a different kind of ocean, a fully immersive neural environment coextensive with the one they physically swam within.

What’s so interesting about this—at least for me—is the implication that REM sleep, and, thus, by extension, the very possibility of animals dreaming, was made possible by immersion in an all-encompassing spatial environment such as the sea. In other words, it took the vast black depths of the ocean to facilitate the kind of uninterrupted, meditative stillness in which REM sleep could best occur. Those ancestral cells then survived into our own mammalian brains, and, by dreaming, it’s perhaps a bit like we retreat back into some lost experience of the oceanic.

In any case, the study’s authors are probably rolling their eyes at this point, but so much comes to mind here—everything from H.P. Lovecraft’s marine-horror stories and their alien call of the deep—such as “The Shadow Over Innsmouth”—to the speculative idea that there might be other spatial environments, comparable to the ocean, that, after long-enough exposure, could inspire unique neurological processes otherwise impossible in traditional environments.

I’m thinking of Jeremy Narby’s strange book, Cosmic Serpent: DNA and the Origins of Knowledge, about human culture amidst the impenetrable rain forests of the Americas, or even the long-running sci-fi trope of the human mind expanding in a psychedelic encounter with deep space.

In fact, this makes me wonder about the landscapes of other planets, and whether crushingly powerful gravitational regimes in alien superstorms or bizarre swirling ecosystems deep inside liquid rock might affect the neurological development of species that live there. What other kinds of sleep are environmentally possible? Does every planet come with a different kind of dreaming? Can the design or formation of new kinds of space catalyze new forms of sleep? Are there deeper or higher levels of the brain, so to speak, waiting to appear in radically different spatial environments?

We already have astrobiology, astrogeology, even astrolinguistics, but I wonder what it would look like to study sleep on other worlds. Exosomnology.

“Each dive feels like floating into a science fiction film”

It’s hard to resist a headline claiming that “otherworldly mirror pools and mesmerizing landscapes” have been “discovered on [the] ocean floor.” Otherworldly mirror pools, like some sort of magic cauldron at the bottom of the sea.

But it’s equally hard to parse what exactly this article is stating. It would appear that unusual geological structures found 2,000 meters below the surface of the Gulf of California have had the superficial effect of resembling mirror images of the rocks below them:

While exploring hydrothermal vent and cold seep environments, Dr. Mandy Joye (University of Georgia), and her interdisciplinary research team discovered large venting mineral towers that reach up to 23 meters in height and 10 meters across. These towers featured numerous volcanic flanges that create the illusion of looking at a mirror when observing the superheated (366ºC) hydrothermal fluids beneath them.

In other words, this sounds more like a useful analogy: the rocks up here look like the rocks down there. It’s as if we’re looking into a mirror.

But what I wish this meant—and perhaps it does, but I’m simply misreading the article—is that bizarre thermal effects, combined with unusually high dissolved-metal content in the water, has created a series of mirror planes, or literally reflective, high-density water tables in the deep ocean that visually duplicate anything above or below them.

Because, if so, imagine the possibilities for turning these into lenses, like some wild, far-future, deep-sea water telescope in which light is bounced back and forth amongst dissolved-metal mirrors hovering in the water table. You could concentrate and focus light in the deep ocean, using naturally occurring, highly-mineralized thermal boundaries, perhaps suggesting a new type of visual-communication network in the sea. Future Navy signaling tech, using nothing but water.

Anyway, whatever the case may be, the poetry of this is incredible. Silvered planes in the ocean forming other-worldly, black labyrinths suddenly illuminated by the lights of a passing submarine.

Phantom/Null

[Image: Saxenburgh Island, from Andrew Pekler’s Phantom Islands].

Musician Andrew Pekler has composed soundtracks for “phantom islands,” or “islands that had existed on maps but not, as it turned out, in reality,” The Wire reports.

“Though a few of them were invented by unscrupulous captains seeking glory (or just further commissions),” Pekler explained to The Wire, “most phantom islands were unintentional fictions—the results of the imprecise science of navigation, clouds, fog banks and icebergs being mistaken for land, and wishful thinking.”

The accompanying website is pretty rad (although it apparently does not work in mobile), though, fair warning, it will easily consume a great deal of your afternoon at the office.

[Image: Antillia Island, from Andrew Pekler’s Phantom Islands].

While reading about Pekler’s work, I was reminded of the so-called “Null Island” effect, a different kind of phantom island that invisibly inhabits the space at 0°N, 0°E in the Atlantic Ocean off the west coast of Africa.

“Every day, countless people seeking digital directions on their computers and smartphones are diverted to an isolated spot on the Atlantic Ocean, 1,000 miles or so off the coast of Africa, where the Prime Meridian and the equator intersect,” the Wall Street Journal explains. “It’s called Null Island.”

This digital “island”—the paper describes it as “the default destination for mistakes”—exists as a result of programming errors in geographic information systems (GIS).

“Unfortunately, due to human typos, messy data, or even glitches in the geocoder itself,” Tim St. Onge wrote for the Library of Congress back in 2016, “the geocoding process doesn’t always run so smoothly. Misspelled street names, non-existent building numbers, and other quirks can create invalid addresses that can confuse a geocoder so that the output becomes ‘0,0’. While this output indicates that an error occurred, since ‘0,0’ is in fact a location on the Earth’s surface according to the coordinate system, the feature will be mapped there, as nonsensical as the location may be. We end up with an island of misfit data.”

[Image: Hunter Island, from Andrew Pekler’s Phantom Islands].

Alas, Andrew Pekler’s Phantom Islands project doesn’t include a soundtrack for Null Island, but perhaps other musicians and sound designers will take that as a challenge. A fictional ethnomusicology for digital nowhere.

(Thanks to @RJCeetoo for the heads up about Phantom Islands and to Wayne Chambliss for telling me about Null Island many years ago.)

Sunken Cities

[Image: Raising a house to help survive future floods; photo by Eliot Dudik, courtesy The New York Times].

The climate change-induced flooding of coastal cities along the U.S. eastern seaboard has already begun, the New York Times suggests.

“For decades, as the global warming created by human emissions caused land ice to melt and ocean water to expand, scientists warned that the accelerating rise of the sea would eventually imperil the United States’ coastline,” we read. “Now, those warnings are no longer theoretical: The inundation of the coast has begun.” In many places, “the sea is now so near the brim in many places that [scientists] believe the problem is likely to worsen quickly.”

The article is full of specific details that would not be out of place in a well-constructed novel, including dead lawns killed by exposure to seawater, vacuum trucks sent out “to suck saltwater off the streets,” and “huge vertical rulers” installed along roads to help drivers judge if the floodwaters “are too deep to drive through.”

These are the new, everyday practices of life on a future seabed: preparatory behaviors as the waters rise and whole communities face permanent inundation.

What’s so interesting about this, in fact, is the apparent lack of panic and catastrophe. While this seeming calmness is no doubt based purely in denial—not just denial that excessive carbon dioxide in the atmosphere retains more heat, leading to warming, but denial of the fact that this is the new normal, that these floods are not flukes but early glimpses of a fundamentally transformed landscape to come—people are nonetheless simply getting on with their lives, even as radical change occurs around them at every scale.

I’m still haunted by a small detail from a similar story published a few years ago, following Hurricane Sandy, about a place called Broad Channel, an outer neighborhood of New York City. There, rising coastal waters have been causing more and more flooding, to the extent that it has become a regular occurrence—not something terrifying, just mildly irritating.

This is true to the extent that residents have now developed otherwise calm and perfectly rational ways of warning one another that the waters are back, that the streets are flooding, and—more to the point—that they should perhaps consider moving their cars.

Broad Channel is now “a place where residents cling to tide clocks and, some joke, every child gets wading boots for Christmas. Neighbors will honk a car horn in the middle of the night to warn others of an approaching tide, and some have made pencil markings on their homes to show water levels from storms past.”

If we ask ourselves what life will be like in the Anthropocene, after the ever-mounting effects of climate change become real, it’s worth remembering these people “honk[ing] a car horn in the middle of the night to warn others of an approaching tide.”

In other words, the Anthropocene will look perfectly normal: people will simply vacuum-pump seawater out of their carports and garages, scrub encrusted salt from the walls of the homes, give each other waterproof boots for Christmas, and otherwise go on as if the world hasn’t changed.

The secret of the Anthropocene is that it’s just another kind of everyday life.

Immersive and Oceanic

By now you’ve no doubt seen Hyper-Reality, the new short film produced by visualization wunderkind Keiichi Matsuda, whose early video experiments, produced while still a student at the Bartlett School of Architecture, I posted about here a long while back.


As you can see in the embedded video, above, Matsuda’s film is a POV exploration of information overload, identity gamification, and the mass burial of public space beneath impenetrable curtains of privately relevant, interactive marketing data, all cranked up to the level of cacophony; when it all shuts off at one point, leaving viewers stranded in a nearly silent, everyday supermarket, the effect is almost therapeutic, an intensely relieving escape back to cognition free from popup ads.

[Image: From Hyper-Reality by Keiichi Matsuda].

I was reminded of Matsuda’s film, however, by the recent news that so-called heads-up displays, or HUDs, are coming to an underwater experience near you: the U.S. Navy has developed an augmented reality helmet for undersea missions.

This unique system enables divers to have real-time visual display of everything from sector sonar (real-time topside view of the diver’s location and dive site), text messages, diagrams, photographs and even augmented reality videos. Having real-time operational data enables them to be more effective and safe in their missions—providing expanded situational awareness and increased accuracy in navigating to a target such as a ship, downed aircraft, or other objects of interest.

Wandering among enemy seamounts, swimming through immersive 3-dimensional visualizations of currents and tides, watching instructional videos for how to infiltrate an adversary’s port defenses, the U.S. Navy attack crews of the near-future will be like characters in an aquatic Hyper-Reality, negotiating drop-down menus and the threat of moray eels simultaneously.

[Image: From Hyper-Reality by Keiichi Matsuda].

This raises the question of how future landscape architects, given undersea terrains as a possible target of design, might use augmented reality on the seabed.

Recall the preservation program underway today in the Baltic Sea, whereby historically valuable shipwrecks are being given interpretive signage to remind people—that is, possible looters—that what they are seeing down there is not mere debris. They are, in effect, swimming amidst an open-water museum, a gallery of the lost and sunken.

So here’s to someone visualizing the augmented reality underwater shipwreck museum of tomorrow, narratives of immersive data gone oceanic.

Marine Acoustic Zones

Outside looks at the idea of “acoustic sanctuaries” in the sea, designed to help marine life communicate free of “anthropogenic noise,” whether created by military sonar or commercial shipping. Meanwhile, how much would I love to visit an “acoustic sanctuary” on land—a landscape deliberately cleared of “anthropogenic noise”—almost like the sound gardens and acoustic forestry of a designer like David Benqué.

Greek Gods, Moles, and Robot Oceans

[Image: The Very Low Frequency antenna field at Cutler, Maine, a facility for communicating with at-sea submarine crews].

There have been about a million stories over the past few weeks that I’ve been dying to write about, but I’ll just have to clear through a bunch here in one go.

1) First up is a fascinating request for proposals from the Defense Advanced Research Projects Agency, or DARPA, who is looking to build a “Positioning System for Deep Ocean Navigation.” It has the handy acronym of POSYDON.

POSYDON will be “an undersea system that provides omnipresent, robust positioning” in the deep ocean either for crewed submarines or for autonomous seacraft. “DARPA envisions that the POSYDON program will distribute a small number of acoustic sources, analogous to GPS satellites, around an ocean basin,” but I imagine there is some room for creative maneuvering there.

The idea of an acoustic deep-sea positioning system that operates similar to GPS is pretty interesting to imagine, especially considering the strange transformations sound undergoes as it is transmitted through water. To establish accurately that a U.S. submarine has, in fact, heard an acoustic beacon and that its apparent distance from that point is not being distorted by intervening water temperature, ocean currents, or even the large-scale presence of marine life is obviously quite an extraordinary challenge.

As DARPA points out, without such a system in place, “undersea vehicles must regularly surface to receive GPS signals and fix their position, and this presents a risk of detection.” The ultimate goal, then, would be to launch ultra-longterm undersea missions, even establish permanently submerged robotic networks that have no need to breach the ocean’s surface. Cthulhoid, they will forever roam the deep.

If you think you’ve got what it takes, click over to DARPA and sign up.

2) A while back, I downloaded a free academic copy of a fascinating book called Space-Time Reference Systems by Michael Soffel and Ralf Langhans.

Their book “presents an introduction to the problem of astronomical–geodetical space–time reference systems,” or radically offworld navigation reference points for when a craft is, in effect, well beyond any known or recognizable landmarks in space. Think of it as a kind of new longitude problem.

The book is filled with atomic clocks, quasars potentially repurposed as deep-space orientation beacons, the long-term shifting of “astronomical reference frames,” and page after page of complex math I make no claim to understand.

However, I mention this here because the POSYDON program is almost the becoming-cosmic of the ocean: that is, the depths of the sea reimagined as a vast and undifferentiated space within which mostly robotic craft will have to orient themselves on long missions. For a robotic submarine, the ocean is its universe.

3) The POSYDON program is just one part of a much larger militarization of the deep seas. Consider the fact that the U.S. Office of Naval Research is hoping to construct permanent “hubs” on the seafloor for recharging robot submarines.

These “hubs” would be “unmanned, underwater pods where robots can recharge undetected—and securely upload the intelligence they’ve gathered to Navy networks.” Hubs will be places where “unmanned underwater vehicles (UUVs) can dock, recharge, upload data and download new orders, and then be on their way.”

“You could keep this continuous swarm of UUVs [Unmanned Underwater Vehicles] wherever you wanted to put them… basically indefinitely, as long as you’re rotating (some) out periodically for mechanical issues,” a Naval war theorist explained to Breaking Defense.

The ultimate vision is a kind of planet-spanning robot constellation: “The era of lone-wolf submarines is giving away [sic] to underwater networks of manned subs, UUVs combined with seafloor infrastructure such as hidden missile launchers—all connected to each other and to the rest of the force on the surface of the water, in the air, in space, and on land.” This would include, for example, the “upward falling payloads” program described on BLDGBLOG a few years back.

Even better, from a military communications perspective, these hubs would also act as underwater relay points for broadcasting information through the water—or what we might call the ocean as telecommunications medium—something that currently relies on ultra-low frequency radio.

There is much more detail on this over at Breaking Defense.

4) Last summer, my wife and I took a quick trip up to Maine where we decided to follow a slight detour after hiking Mount Katahdin to drive by the huge antenna field at Cutler, a Naval communications station found way out on a tiny peninsula nearly on the border with Canada.

[Image: The antenna field at Cutler, Maine].

We talked to the security guard for a while about life out there on this little peninsula, but we were unable to get a tour of the actual facility, sadly. He mostly joked that the locals have a lot of conspiracy theories about what the towers are actually up to, including their potential health effects—which isn’t entirely surprising, to be honest, considering the massive amounts of energy used there and the frankly otherworldly profile these antennas have on the horizon—but you can find a lot of information about the facility online.

So what does this thing do? “The Navy’s very-low-frequency (VLF) station at Cutler, Maine, provides communication to the United States strategic submarine forces,” a January 1998 white paper called “Technical Report 1761” explains. It is basically an east coast version of the so-called Project Sanguine, a U.S. Navy program from the 1980s that “would have involved 41 percent of Wisconsin,” turning the Cheese State into a giant military antenna.

Cutler’s role in communicating with submarines may or may not have come to an end, making it more of a research facility today, but the idea that, even if this came to an end with the Cold War, isolated radio technicians on a foggy peninsula in Maine were up there broadcasting silent messages into the ocean that were meant to be heard only by U.S. submarine crews pinging around in the deepest canyons of the Atlantic is both poetic and eerie.

[Image: A diagram of the antennas, from the aforementioned January 1998 research paper].

The towers themselves are truly massive, and you can easily see them from nearby roads, if you happen to be anywhere near Cutler, Maine.

In any case, I mention all this because behemoth facilities such as these could be made altogether redundant by autonomous underwater communication hubs, such as those described by Breaking Defense.

5) “The robots are winning!” Daniel Mendelsohn wrote in The New York Review of Books earlier this month. The opening paragraphs of his essay are is awesome, and I wish I could just republish the whole thing:

We have been dreaming of robots since Homer. In Book 18 of the Iliad, Achilles’ mother, the nymph Thetis, wants to order a new suit of armor for her son, and so she pays a visit to the Olympian atelier of the blacksmith-god Hephaestus, whom she finds hard at work on a series of automata:

…He was crafting twenty tripods
to stand along the walls of his well-built manse,
affixing golden wheels to the bottom of each one
so they might wheel down on their own [automatoi] to the gods’ assembly
and then return to his house anon: an amazing sight to see.

These are not the only animate household objects to appear in the Homeric epics. In Book 5 of the Iliad we hear that the gates of Olympus swivel on their hinges of their own accord, automatai, to let gods in their chariots in or out, thus anticipating by nearly thirty centuries the automatic garage door. In Book 7 of the Odyssey, Odysseus finds himself the guest of a fabulously wealthy king whose palace includes such conveniences as gold and silver watchdogs, ever alert, never aging. To this class of lifelike but intellectually inert household helpers we might ascribe other automata in the classical tradition. In the Argonautica of Apollonius of Rhodes, a third-century-BC epic about Jason and the Argonauts, a bronze giant called Talos runs three times around the island of Crete each day, protecting Zeus’s beloved Europa: a primitive home alarm system.

Mendelsohn goes on to discuss “the fantasy of mindless, self-propelled helpers that relieve their masters of toil,” and it seems incredibly interesting to read it in the context of DARPA’s now even more aptly named POSYDON program and the permanent undersea hubs of the Office of Naval Research. Click over to The New York Review of Books for the whole thing.

6) If the oceanic is the new cosmic, then perhaps the terrestrial is the new oceanic.

The Independent reported last month that magnetically powered underground robot “moles”—effectively subterranean drones—could potentially be used to ferry objects around beneath the city. They are this generation’s pneumatic tubes.

The idea would be to use “a vast underground network of pipes in a bid to bypass the UK’s ever more congested roads.” The company’s name? What else but Mole Solutions, who refer to their own speculative infrastructure as a network of “freight pipelines.”

[Image: Courtesy of Mole Solutions].

Taking a page from the Office of Naval Research and DARPA, though, perhaps these subterranean robot constellations could be given “hubs” and terrestrial beacons with which to orient themselves; combine with the bizarre “self-burying robot” from 2013, and declare endless war on the surface of the world from below.

See more at the Independent.

7) Finally, in terms of this specific flurry of links, Denise Garcia looks at the future of robot warfare and the dangerous “secrecy of emerging weaponry” that can act without human intervention over at Foreign Affairs.

She suggests that “nuclear weapons and future lethal autonomous technologies will imperil humanity if governed poorly. They will doom civilization if they’re not governed at all.” On the other hand, as Daniel Mendelsohn points out, we have, in a sense, been dealing with the threat of a robot apocalypse since someone first came up with the myth of Hephaestus.

Garcia’s short essay covers a lot of ground previously seen in, for example, Peter Singer’s excellent book Wired For War; that’s not a reason to skip one for the other, of course, but to read both. See more at Foreign Affairs.

(Thanks to Peter Smith for suggesting we visit the antennas at Cutler).

The Museum At The Bottom Of The Sea

[Image: Photo by Martin Siegel/Society of Maritime Archaeology, via Der Spiegel].

In 2012, German archaeologists began posting interpretive signs underwater, marking shipwrecks and even crashed airplanes at the bottom of the Baltic Sea as if they are in a museum, in order to make it clear to potential vandals, reckless tourists, and amateur collectors that these are culturally important sites, worthy of preservation.

“Alarmed at the looting of historically valuable shipwrecks in the Baltic Sea,” Der Spiegel reported at the time, “German archaeologists have started attaching underwater signs designating them as protected monuments. Hobby divers and trophy hunters are damaging a precious maritime legacy stretching back thousands of years, they warn.”

The sunken ship seen in the above image, for example, is just one of “some 1,500 marine monuments strewn across the seabed along the coast. The area has a wealth of well-preserved shipwrecks, lost cargo planes and even ancient settlements submerged through subsidence and rising water levels.” That these can be described as monuments is very important: they are not mere wreckage, scattered over the seabed, but artifacts on display for those who can reach them.

[Image: Photo by Martin Siegel/Society of Maritime Archaeology, via Der Spiegel].

The effect is strangely evocative, as if an architectural experiment has been going on beneath the waves of the Baltic Sea for the last few years, in which a museum, entirely without walls and seemingly with only very few visitors, has been secretly installed and constructed. It is a distributed, nonlinear museum of European ruins barely visible in the rising sea.

What’s so interesting from an architectural standpoint, however, is how a group of signs such as these can have such a huge narrative and spatial effect, as if you’ve entered some sort of undefined volumetric space without walls, hidden in the water all around you, a kind of invisible cultural institution stocked with objects that only you and your fellow divers, at that exact moment, can even see.

In fact, it makes me curious how the (totally brilliant and BLDGBLOG-supported) idea of creating a new National Park on the moon might work—and, more to the point, what such a park would really look like. Do we just post a few signs on the lunar surface indicating that historically important artifacts are present up ahead, or do we actually construct some sort of “museum” space there that would more adequately sustain an aura of cultural history?

Either way, it’s both hilarious and deeply strange that we could begin to experiment with what such a park might look like using—of all things—shipwrecks at the bottom of the Baltic Sea, and that German archaeologists, randomly posting cheap signs on the seabed, might have anticipated future strategies of historic preservation in otherwise deeply unearthly situations.

Operation Deep Sleep: or, dormant robots at the bottom of the sea

[Image: An otherwise unrelated photo of lift bags being used in underwater archaeology; via NOAA].

The Defense Advanced Research Projects Agency, or DARPA, is hoping to implement a global infrastructure for storing mission-critical objects and payloads at the “bottom of the sea”—a kind of stationary, underwater FedEx that will release mission-critical packages for rendezvous with passing U.S. warships and UAVs.

It’s called the Upward Falling Payloads program.

The “concept,” according to DARPA, “centers on developing deployable, unmanned, distributed systems that lie on the deep-ocean floor in special containers for years at a time. These deep-sea nodes would then be woken up remotely when needed and recalled to the surface. In other words, they ‘fall upward.'” This requires innovative new technologies for “extended survival of nodes under extreme ocean pressure, communications to wake-up the nodes after years of sleep, and efficient launch of payloads to the surface.”

As Popular Science describes it, it’s a sleeping archive of “‘upward falling’ robots that can hide on the seafloor for years [and] launch on demand.”

And you can even get involved: DARPA is currently seeking proposals for how to realize its vision for Upward Falling Payloads.

DARPA seeks proposals in three key areas for developing the program: Communications, deep ocean ‘risers’ to contain the payloads, and the actual payloads. DARPA hopes to reach technical communities that conduct deep-ocean engineering from the telecom and oil-exploration industry to the scientific community with insights into signal propagation in the water and on the seafloor.

An informative “proposer’s day” will be held on January 25, 2013, where you can learn more about the program. It seems that, just a few years from now, storing objects for at-sea retrieval will be as ordinary as receiving an email.

Briefly, it seems worth mentioning that this vision of waking things up from slumber at the bottom of the sea reads like a subplot from Pacific Rim, or like some militarized remake of the works of H.P. Lovecraft—wherein Lovecraft’s fictional Cthulhu, a monstrous and alien god, is described (by Wikipedia) as “a huge aquatic creature sleeping for eternity at the bottom of the ocean and destined to emerge from his slumber in an apocalyptic age.”

Only, here, it is a gigantic system of military jewelry laced across the seafloor, locked in robotic sleep until the day of its electromagnetic reawakening.

Liquid Radio

Could temporary jets of seawater be used as functioning radio antennas? Apparently so: as PopSci reports, “communications are vital” for vessels at sea, but deck space for “all the large antennas necessary for long-range (and often encrypted) communications” can be hard to come by. “So U.S. Navy R&D lab SPAWAR Systems Center Pacific (SSC Pacific) engineered a clever scheme to turn the ocean’s most abundant resource into communications equipment, making antennas out of geysers of seawater.”

Using arcing vaultworks of oceanwater, like domesticated waves, to beam and receive encrypted telecommunications not only reduces the metal-load of ships—thus also reducing the radar profile of military vessels—it also offers a way to construct “a quick, temporary antenna that could just as easily be dismantled.”

What they [SPAWAR] came up with is little more than an electromagnetic ring and a water pump. The ring, called a current probe, creates a magnetic field through which the pump shoots a steam of seawater (the salt is a key ingredient, as the tech relies on the magnetic induction properties of sodium chloride). By controlling the height and width of the [stream], the operator can manipulate the frequency at which the antenna transmits and receives. An 80-foot-high stream can transmit and receive anywhere from 2 to 400 mHz, though much smaller streams can be used for varying other frequencies, ranging from HF through VHF to UHF.

Turning seawater into a temporary broadcast architecture is absolutely fascinating to me and has some extraordinary design implications for the future. Pirate radio stations made entirely from spiraling pinwheels of saltwater; cell-phone masts disguised as everyday displays spurting seasonally in public parks, from Moscow to Manhattan; TV towers replaced with Busby Berkeley-like aquatic extravaganzas, camouflaging the electromagnetic infrastructure of the city as a gigantic water garden.

[Image: A mountainous display of women closely choreographed with water by Busby Berkeley, via Alexander Trevi’s Pruned].

Given some salt, for instance, the Trevi Fountain could begin retransmitting mobile phone calls throughout the heat-rippling summer landscape of greater Rome. Ultra-refined specialty saltwaters offer dependable signal clarity in audio HD. La Machine de Marly becomes a buried industrial art project, beaming death metal salt hydrologies to garden visitors: a continuous fountain of thundering music on FM, headbanging to seawater hifi. Espionage conspiracies involving elaborate, deep-cover radio links hidden inside public fountains.

So how could this be further explored in the contexts of tidal river waters—Thames Radio!—rogue waves, and even tsunamis? The artistic, architectural, musical, and infrastructural misuse of this technology is something I very much look forward to hearing in the future.
