Scientists Explore Mineral-Rice Seafloor & DDT Dump Sites; Discovery New Methane Seep, Whale Fall
Twelve exploratory dives off California’s coast in previous waste dumping grounds and areas of potential mining will help advance understanding of human impacts on the deep-sea ecosystem

SAN DIEGO – Marine scientists aboard Schmidt Ocean Institute’s research vessel Falkor have completed a 12-day expedition off the coast of Southern California to survey the biodiversity of deep-sea areas rich in minerals that are of interest to deep-sea mining developers around the world.
The expedition, which covered 5,310 square miles, explored nine deep-sea sites, including the offshore site where possibly hundreds of thousands of barrels of toxic waste from the production of the insecticide DDT were dumped from 1947 to 1982.

A barrel thought to contain DDT waste products rests on the bottom of the ocean floor off of the coast of Los Angeles. Many of the barrels, which were dumped between 1947 and 1982, are surrounded by light-colored bacterial matte halos. The halos indicate a change to the microbial community in the sediment and the scientists hope to learn what bacteria are there and what chemicals they are breaking down. 
Researchers use Remotely Operated Vehicle SuBastian to collect sediment push cores and record video footage, data that will be used to add to the assessment on how this stretch of deep sea is responding to DDT. The science team is conducting research on the DDT Dumpsite off the coast of Los Angeles where barrels of chemicals were dumped from 1947-1982.
With an underwater robot, the team of scientists from UC San Diego’s Scripps Institution of Oceanography and the United States Geological Survey collected sediment and biological samples around six barrels to understand the potential ecological effects of the dumpsite and to determine the levels of DDT present in the ecosystem after more than 50 years. The site had been surveyed previously by scientists from UC Santa Barbara and Scripps on previous expeditions.

The goal of the Schmidt Ocean Institute expedition was to establish mineral and biological baselines in the area known as the southern California Borderland, which has the potential for deep-sea mining. The area contains rare earth marine minerals such as ferromanganese and phosphorite that are used in the manufacture of electronics, electric car batteries, solar panels, and other green technologies.
Scientists collected more than 300 samples of seafloor rocks, sediment, seawater, and marine invertebrates to better understand the ecology, mineral and microbial makeup of the relatively unexplored deep-sea system. In collecting samples, researchers also hope to evaluate the therapeutic or drug discovery potential of deep-sea microbes found in mineral-rich areas.
“We are just beginning to understand the valuable resources of our ocean ecosystem,” said Wendy Schmidt, co-founder of Schmidt Ocean Institute. “We can’t protect what we don’t know and understand, and the human impact on our ocean over the past 75 years has had a detrimental effect on its health and on the many ocean systems that support life on land. We expect the knowledge gained from this expedition will inform policy, management and stewardship of the deep sea, so that episodes of dumping toxic waste, such as this one, will not happen again”


Principal Investigator Dr. Lisa Levin (of Scripps Institution of Oceanography) sorts through organisms that have grown on a piece of wood. The wood was placed at depth well before the expedition to test what creatures would colonize it. 
Dr. Greg Rouse (of Scripps Institution of Oceanography) separates specimens from deep-sea samples before examining them under a microscope while on board Schmidt Ocean Institute’s research vessel Falkor.
The 12 expedition dives were broadcast live to the public on Schmidt Ocean Institute’s social media channels. During one of the dives to explore the DDT site, scientists discovered a whale fall–the seafloor location where the remains of a whale come to rest. Scientists also identified a new area of methane seepage. Marine biologists consider both areas a focus of specialized research because of the unique habitat they create.

Remotely Operated Vehicle SuBastian collects a sponge in which several different types of organisms were contained. From this view alone, scientists were able to identify shrimp, amphipods, a ctenophore and a worm tube on the rim. One focus of this expedition is to assess the biological communities living amongst mineral substrates. 
A squat lobster perches atop a Bubblegum Coral on the San Juan Seamount in the Southern California Borderland. The image was taken by Remotely Operated Vehicle SuBastian as researchers investigated several sites where marine minerals are known (or expected) to occur, while assessing the biological communities living amongst the mineral substrates. 
A galaxy siphonophore is documented by ROV SuBastian on descent to the Patton Escarpment. Although a siphonophore may appear to be an individual organism, each specimen is in fact a colonial organism – a collection of highly specialized working parts. Some parts catch prey, others digest food, some parts reproduce and others direct the action by swimming. The Patton Escarpment marks the edge of the continental shelf off California.
“Establishing ecological baselines in the deep sea allows us to track changes over time and better understand the consequences of human actions,” said Chief Scientist Dr. Lisa Levin, a professor of biological oceanography at Scripps Institution of Oceanography. “The DDT dump site provides evidence of a large human footprint in the deep ocean, but we are just starting to identify the effects on local marine communities.”
The information the team collected at the DDT barrel disposal site will be compared to animals and microbes at more distant sites in order to assess the current concentrations and effects of DDT in the region. The samples will return to Scripps Institution of Oceanography where scientists will conduct further analysis and DNA sequencing.

The Camden International Film Festival: Surveying the Maine Coast, Tracking Down Berlin Wall Segments, and Targeting Suspects Overseas
By Peter Keough

This is the time of the year when film festivals proliferate and now they are more accessible than ever because the pandemic has forced them to go virtual.
Great documentary films can be seen in the comfort and safety of your home courtesy of the Boston Latino International Film Festival (Sept. 23-27; www.bliff.org), Boston Film Festival (Sept. 24-27; www.bostonfilmfestival.org/index.shtml), and Roxbury International Film Festival (Sept. 30-Oct. 5; www.roxfilmfest.com). And two festivals in the coming weeks — the GlobeDocs Film Festival (Oct. 1-12; globedocs2020.eventive.org/welcome), which I will cover next week, and Camden International Film Festival (Oct. 1-12) — focus exclusively on documentaries.
The latter, usually held in picturesque Camden, Maine, and neighbouring towns, has reliably programmed recent nonfiction films that are ambitious both in style and content. Here are three such films I recommend — inventive and unique studies of people interacting with their habitat and surroundings.
Maine filmmaker Ian Cheney’s “The Long Coast” (it can be streamed on Oct. 4 and is available within a 72-hour window) is a gorgeous and engrossing tour of his state’s coastline and those who live and work there. It evokes films as disparate as Frederick Wiseman’s rigorously observational “Belfast, Maine” (1999) and Lucien Castaing-Taylor and Verena Paravel’s intimately rhapsodic “Leviathan” (2012).
Divided into five parts and an epilogue, “The Long Coast” features seascapes as ravishing as paintings by Whistler and Turner and down-to-earth conversations with those who make their living from the sea. The latter includes a “Winkler,” who pries periwinkles from cracks in mossy stones, and the proprietors of fish-processing plants where a slab of frozen lobster bait is a surreal plank of pink ice with eyes. Cheney excels in showing the relationship between the environment and its inhabitants, hinting at the possibility of a sustainable interdependence but warning of environmental dangers ahead. Lots of kelp on display, but who knew kelp could be so photogenic?

Indie Film: ‘The Long Coast’ Lets the Stories of Maine Fishermen Convey the Challenges Facing the Ocean
By Dennis Perkins

I love Maine.
Only living here since 1987 makes me “from away,” and I’ve come to accept that. But the Perkinses come from here, and Maine was the place where we escaped every summer through my childhood. My parents have retired to the (now winterized) ancient house on a cliff overlooking the waters off of Phippsburg, where, as a child, I goggled at the date inscribed on the side of the house. It started with an “18,” and I’d stare at it as if it were from another planet.
So, my native cred shaky as it is, I grew up staring out on this rocky, cold, unimaginably beautiful shoreline. And I love it. Yet, writing about Maine movies as I do, sometimes I do imagine I’ve just seen enough documentaries about the picturesquely stark Maine coast. (Or as fellow from-away Mainer John Hodgman describes them in his book “Vacationland,” Maine’s “painful beaches.”)
“The Long Coast,” from Maine filmmaker Ian Cheney and available to stream through PMA Films, is the sort of movie that disabuses one of that notion. A meditative mix of interviews, striking but unobtrusive cinematography, and, yes, Maine’s uniquely picturesque, majestic coastal beauty, “The Long Coast” is a portrait in collage and montage. The 86-minute film’s five segments (and a sombre, chilly COVID-era epilogue) have plenty to say – about Maine’s working ocean culture, global warming, overfishing, conservation, and innovation. But “The Long Coast’s” impact comes when you step back. The individual pieces are uniformly fascinating, but the overall picture Cheney presents of Maine’s vast and varied (and ever-changing) fishing ecosystem is a down-home masterpiece.
The interviews are conducted in wide shots, each subject-centred alone in the frame. A clammer explains the lonely benefits of his trade, while we see the mucky work up close. A young lobsterwoman tells how she worked her way through high school, hauling traps before captaining a ship of her own. Oyster farmers – both tank- and ocean-based – extol the benefits their industriousness brings to the ecosystem, while a 40-year lobsterman explains why he saw it was time to switch to farming oysters and kelp. Two women (a kelp farmer and a retired former lobsterwoman) relate how their very dreams have been infiltrated by their chosen professions.
Elvers, clams, lobsters, oysters, salmon, alewives, even lowly periwinkles (which one man cites as key to his decades of self-employment). All variously bountiful, all subject to effects of overfishing, climate change, industrial farming, conservation and plain old bad luck. And all as interconnected, in ways Cheney draws delicately throughout his film, as are the lives of the ocean’s scuttling, squirming, swarming creatures.

It sounds facile to say that humans and the things they fish, dig, and farm are all interdependent. But “The Long Coast” presents that fact as so intrinsic to the individual lives spotlighted within that the message emerges like something so basic as to be inarguable. More straightforward documentaries might make the case for adaptation and conservation with alarmist (if inescapable) lectures, but Cheney weaves a net of simple fact. A woman notes plainly that the Maine sea urchins her husband once pulled up with lucrative ease are gone, as are the once bountiful cod lobsterman notes once made up a fleet’s main baitfish.
The young lobsterwoman has branched out into oyster farming because overfishing and resultant restrictions necessitated it. “It’s another way of staying on the ocean,” the woman states, as she hauls a clattering wireframe full of her oysters from the cold sea.
Cheney (as seen in his similarly observant documentary about a single Maine field, “Thirteen Ways”) always comes back to the source. The ocean – seen here from above, below and aboard various choppy vessels – is the reality of working life for thousands of Mainers. And the ocean is always changing. Changing along with the tides isn’t a “from-away” idea, it’s intrinsic to the life of those who depend on them. The clammer, who’s seen local mussel stocks all but disappear and his chosen river’s clams becoming sparse, talks about attending a seminar on scallop aquaculture, noting simply, “We need technology because we don’t know how much longer Mother Nature’s gonna keep providing stuff for us.”
So Mainers are providing solutions. Oyster tanks utilize other fishing industry waste to feed their crops while not crowding out fishing grounds or creating pollutants of their own. (Although, as one farmer notes, there is still some consumer snobbery around tank oysters.) A longtime bait merchant explains how the lack of cod has meant a boon to pork producers, whose castoff pig hides are becoming a lobster trap staple. (There was some diner unpleasantness before they figured out to shave the hides.) An eel fisher (and beauty salon owner) lays out her plans to cut out the foreign middlemen in the elver harvest. (We ship the comically adorable baby glass eels to China, which then sells the full-grown eels back to Maine.)
The thing about “The Long Coast” is that global and environmental concerns – so often simplified into shrill political talking points – are as vital to the livelihoods of Maine’s ocean workers as are their nets, boats, and that cool short-handled hoe clammers use. Cheney’s subjects know that, and so, obviously, does he. “The Long Coast” takes the long view, and it’s a gorgeously photographed, exquisitely edited and uniquely Maine view indeed.
“The Long Coast” can be rented through PMA Films’ virtual video store at portlandmuseum.org/films. The 72-hour ticket for this 86-minute film is a very-worth-it $10, with a portion of each rental going right to PMA Films.
