Still Seeking Moby Dick: Spotting Whales from Space

Modern space technology and artificial intelligence have combined to enhance the conservation of marine animals: the new service, “SPACEWHALE”, developed by a team of creative scientists in Germany and the UK, detects whales from space. Supported by funding from the European Space Agency (ESA) Space Solutions program (https://spacesolutions.esa.int/), this fundamental research enables whales and other large marine megafauna to be surveyed at an unprecedented scale. Earth Observation from satellites is developing fast and within a few years, space technology companies aim to provide daily high-resolution images of the whole globe. SPACEWHALE makes use of this to boost marine research and conservation.
In contrast to previous whale monitoring by ship or aircraft, satellite images cover the global ocean surface. SPACEWHALE does not only detect whales but also other large marine animals. Many questions that previously required individual biological studies can now be answered with just a few clicks. Which areas are especially used by marine mammals? When do whales pass through a certain region during their migration? With the answers to these and other questions, solutions can be found that combine species protection on the one hand and human use of the seas on the other. For example, periods can be determined in which oil and gas or offshore wind farm activities cause the least disturbance to wildlife.
“Earth Observation by satellites is currently developing rapidly. It will only take a few more years for space companies to provide high-resolution images of the entire globe on a daily basis,” says project manager Caroline Höschle from BioConsult SH. “That makes SPACEWHALE a forward-looking tool, but it already performs fantastically well with the imagery we have today. Over 70 % of the Earth’s surface is covered by water and thus large areas are still unexplored. The intelligent use of satellite imagery now brings us a lot of previously inaccessible data. SPACEWHALE is part of this revolution,” Höschle continues. “SPACEWHALE is a fast and efficient means of surveying whales – at a comparable cost to traditional methods for only a small area of the oceans.
SPACEWHALE uses satellite imagery with a resolution of 31 cm per pixel across the ground, meaning that a 23 m fin whale has a length of around 77 pixels when it fully surfaces. “This is currently the highest commercially available resolution and though the images appear rather coarse, the resolution is just perfect to detect large whales,” says data scientist Dr. Grant Humphries from HiDef Aerial Surveying Ltd.
Automatic image recognition is now widely used for many applications in our daily life but to be successful, it needs to be based on a large set of training images. So far, there are hardly any satellite images of large whales that could be used as training images. The staff of BioConsult SH and HiDef Aerial Surveying Ltd. found a solution to this problem: they used digital aerial images of the smallest baleen whales, namely the 7 to 10-metre-long minke whales, which came from monthly whale monitoring flights of offshore wind farms. The researchers were able to show that the algorithm trained in this way could subsequently recognise 23-metre-long fin whales and other whale species on satellite images.
Initial trials of SPACEWHALE proved successful: in the Mediterranean Sea, the algorithm detected almost twice as many fin whales as a previous manual investigation. In the Bay of Biscay, the algorithm detected fin whales and three other whale species. SPACEWHALE successfully counted humpback whales off the Hawaiian and Southern Right Whales off the Argentinian coasts.
“SPACEWHALE makes a significant contribution to marine conservation; artificial intelligence combined with satellite images offers completely new opportunities,” says Höschle. The application of SPACEWHALE can help identify critical habitats of whales and inform marine spatial planning and impact assessments of offshore developments. Accelerating climate change is also expected to cause profound changes, especially in Arctic waters, with associated declining ice cover and expanding human activities in whale habitats. Historical ranges of whales are changing. “With SPACEWHALE, we want to contribute to the targeted implementation of protection measures for great whales, even in the most remote areas,” says Höschle. “ESA Space Solutions are pleased to support the development of the SPACEWALE service; it demonstrates that the possible applications of satellite data are endless and only becoming more so with new satellite capabilities, such as higher resolution imagery and improved coverage, being made available at an ever-increasing rate. This project testifies ESA engagement in protecting biodiversity and natural eco-systems, in support to the Green Deal objectives.” – Rita Rinaldo, Head of the Partner-led and Thematic Initiatives Section, ESA Space Solutions.

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.
