The White Mountains of New Hampshire have some relatives on the bottom of the North Atlantic Ocean: extinct volcanoes that were built by a “hotspot” below Earth's crust. The underwater volcanoes form the New England Seamount. It's a chain of about 30 peaks. It begins a couple of hundred miles from Cape Cod and extends hundreds of miles eastward. Its tallest peaks rise a mile and a half from the sea floor. The peaks were built when one of the plates that make up Earth's crust slid over a hotspot below the crust. Molten rock pushed upward, building the mountains. The White Mountains in New Hampshire took shape about 125 million years ago, with the seamounts coming later. The last of them was formed about 80 million years ago. An expedition in the summer of 2021 used sonar to map a large region of the seamounts. It found some new peaks, and discovered that an expected one wasn't there. The expedition also used underwater robots to look at the seamounts up close. It found that the summit of one was completely covered with small balls made of iron, manganese, and other metals. And it found an abundance of life: corals, fish, jellyfish, sponges, crabs, and many other creatures. Some of them were species that no one had ever seen before, such as a brilliant red jellyfish. There's still a lot to learn about the New England Seamounts. But we know a lot more than we just did a few years ago—about these hidden relatives of the White Mountains.

The Green Party is calling for bottom trawling on seamounts to stop, following a 'white paper' from Sealord which the party calls greenwashing. Stella spoke to the party's ocean and fisheries spokesperson, Eugenie Sage, on the matter.

When plate tectonics was adopted in the 1960s and early '70s, researchers quickly mapped out plate movements. It seemed that plates moved as rigid caps about a pole on the Earth's surface. But since then, a lot of evidence has accumulated suggesting that plates are not, in fact, totally rigid. In fact, we can see them flex in response to stresses that are imposed on them. Such stresses can arise on plate boundaries, such as when two plates collide and one plate flexes down to subduct under the other. For example, we see a flexural bulge in Northern India where the Indian plate bends down under the Eurasian plate. Similar bulges are seen at subduction zones where the oceanic lithosphere flexes up before it bends down into a trench, such as off the eastern coast of Japan. Stresses can also be imposed in plate interiors when the plate is subjected to a load, such as a volcano or a sedimentary basin. An example of sediment loading occurs in river deltas, such as that of the Ganges in the Bay of Bengal. Our guest today pioneered an ingenious method of determining the flexural strength of oceanic plates. The method uses the flexural sag of plates in response to the weight of seamounts, most of which were emplaced on their surfaces by mid-ocean eruptions. His results suggest that less than half of an oceanic plate actually contributes to its elastic strength. The rest is brittle (top layer) or ductile on the relevant time scales (bottom layer).Tony Watts is Professor of Marine Geology and Geophysics at the University of Oxford and a Fellow of the Royal Society.

Welcome back to Episode 13 of The EcoThink Podcast! This week Yuko and I sit down for a very exciting talk with Dr. Cherisse Du Preez who is an amazing deep sea marine biologist with the Department of Fisheries and Oceans here in Canada. Listen to her blow our minds as we talk about the amazing biodiversity that exists in the deep ocean here in the Pacific Northwest, the extreme nature of the habitat near deep sea vents and on sea mounts, and how human impacts have already reached this mysterious part of the world.   Also, Cherisse shares with us how to keep up with current work, as next week on June 15th she and her team will be off to explore Canada's deepest sea mounts for the first time. I recommend following Cherisse on social media @CherisseDuPreez to keep up to date with new developments, and check out #pacificseamounts2021 to follow the expedition as they live stream their findings!   Sources and additional links:   Pacific Seamounts 2021 LIVE DIVE webpage: https://www.oceannetworks.ca/pacific-seamounts-2021 The Pacific Seamounts 2021 story page: https://www.oceannetworks.ca/pacific-seamounts-expedition-2021 Follow Cherisse on Instagram, Twitter, or Facebook @CherisseDuPreez   Past expedition hashtags: #PacificSeamounts2018 ; #PacificSeamounts2019   Upcoming expedition hashtag: #PacificSeamounts2021   Ocean Networks Canada: https://www.oceannetworks.ca/   Rapid deep ocean deoxygenation and acidification threaten life on Northeast Pacific seamounts by Tetjana Ross, Cherisse Du Preez, Debby Ianson: https://onlinelibrary.wiley.com/doi/10.1111/gcb.15307   Recommended videos: Seamounts: https://youtu.be/hjPf_zmhU00 Hot vents: https://youtu.be/04nrtlWwlx8

The largest Atlantic US Marine Monument is now open for commercial fishing after the President of the United States signs an Executive Order to allow fishing to occur within the boundaries. There is a reason why this happened and it has to do with the manner in which the Monument was designated. Take a listen to the show to find out what I mean.

Due to a technical error, this episode is late and maybe a little out of date. But, it's still Ryan, Corey and James discussing the top stories of the week... just a half-week too late.

Southern New England states are hungry for renewable energy. There’s energy up north, but there are hurdles to bringing down to southern states. This week, we look at the stalling of wind energy in Maine, and the controversy over a project that would bring hydro-electric power from Quebec to the New England grid. Plus, we have updates to government plans to clean up the Long Island Sound, install high speed rail, and conserve land – or not – in our region. And we learn what makes “New England’s magazine” tick. Buckle up. Opponents to Northern Pass, a project to bring hydro- electric power from rivers in Quebec through New Hampshire to the New England grid, has drawn opposition from Granite Staters who worry that transmission towers would disturb pristine wilderness.

Photo by Fred Bever for NENC In Maine, wind energy had a decade of rapid growth, but now the industry has hit the doldrums in the Pine Tree State. As Maine Public Radio’s Fred Bever reports, no big new wind projects are likely to go live any time soon. And it could cost billions to unlock enough of the state’s wind resource – the best in the region – to serve southern New England’s thirst for renewable energy. Next door in New Hampshire, Northern Pass is a proposal to run 192 miles of new power lines from Canada, through much of the state. The current proposed Northern Pass route would bury the line in the White Mountains as a concession to opponents. Photo courtesy of Northern Pass The project is a collaboration between the regional utility Eversource, and Hydro-Quebec, which is owned by Quebec’s provincial government. The utilities say the $1.6 billion Northern Pass project would transport 1,090 megawatts of electricity from Quebec – which derives more than 90 percent of its power from hydroelectric dams – to the New England power grid. Since the first route was proposed in 2011, Northern Pass has generated considerable controversy in New Hampshire. Now, the issue is being considered in the state legislature, and hearings are expected to continue throughout the summer.  Our guest Nancy West has been covering the back-and-forth for the New Hampshire Center for Public Interest Journalism. How would Northern Pass fit into New England’s energy grid? And just how “clean” a source is hydro-electric power? For answers we turned to Sam Evans-Brown, host of the New Hampshire Public Radio podcast Outside/In – the show about the natural world and how we use it. Evans-Brown says the impacts of Canadian hydro-electric power on our regions grid could be massive. According to Hydro-Quebec, hydro-electric power for the Northern Pass project would come from  dams along La Grande River in the northwest corner of the map, and on the Romaine river on the east side of the map, including two that are currently under construction. Map courtesy of Hydro-Quebec Federal Projects in New England – Updates Last week we learned about how nitrogen runoff from the Connecticut River is leading to the die-off of fish and plant life in Long Island Sound. But the problem is not a new one. The Environmental Protection Agency started closely monitoring nitrogen levels there back in the 1980s. By 2001, the agency set new nitrogen limitations for wastewater treatment plants on the Sound in New York and Connecticut. Now EPA is expected to set lower limits for wastewater treatment plants miles from the Sound, on the Connecticut River.  As New England Public Radio’s Jill Kaufman reports, those plants are wondering if this is their problem to solve. Watch a video about how nitrogen from upriver affects the Long Island Sound: The nation's busiest rail corridor hugs the shoreline along Long Island Sound. The Amtrak trains that serve the Northeast get people from Boston to New York and beyond. The shoreline communities that the trains pass through, want faster, reliable train service that also stops at their local train stations. But a proposed federal plan for high speed rail  would have trains skipping many towns and cities. Robert Lee owns Lee’s Oriental Market in the Historic Hodges Square Village neighborhood of New London, CT. He worried that a rail bypass would hurt development here. Photo by Ryan Caron King for NENC Two weeks ago on the show, we heard from residents angry about lack of public input in the process, and concerned about potential impacts on historic buildings and farmland. Now in the port city of New London, Cassandra Basler reports that some worry the proposed railroad bypass would decimate their city's budget and hold back it's revitalization. Back in August of 2016 President Obama signed an executive order creating a national monument in Maine's North Woods. As NEXT reported, that signature created the Katahdin Woods and Waters National Monument on 87 thousand acres of wilderness east of Baxter State Park. Boaters, in August of 2016, paddle the East Branch of the Penobscot River, which cuts through Katahdin Woods and Waters. Photo by Susan Sharon for Maine Public Now, that monument is one of 27 under review by the Trump administration. Maine Governor Paul LePage says the monument, and its potential to become a national park, pose a real threat to Maine’s forest products industry. Main Public Radio's A. J. Higgins traveled to the nearby town of Millinocket, where he found some monument supporters, including local businesses, who are fighting back. The Department of the Interior is accepting public comments on the review of monuments including Katahdin Woods and Waters, (as well as the Northeast Canyons and Seamounts monument 150 miles off the coast of Cape Cod), through July 10. You can read comments and submit your own at regulations.gov. Your Grandma’s New England Magazine Adapts to Not-Your-Grandma’s New England Yankee Magazine editor Mel Allen. Photo by Jarrod McCabe for Yankee Magazine Google something along the lines of “best clam chowder in Rhode Island” or “best New England beaches” and chances are good you’ll come across newengland.com, the website of Yankee Magazine. (The magazine will be ranking lobster rolls in its next print issue. Of course, John has his own opinions on that topic.) Yankee's tagline is “New England's magazine,” and the periodical turns 82 this year. So what did it mean to be New England’s Magazine in 1935, and what does it mean today? We check in with editor Mel Allen. Once plentiful in New England's rivers, native Atlantic salmon have since all but disappeared. Salmon grow up in freshwater, then go out to the ocean and return inland to spawn. But dams and changing oceanic conditions have destroyed river return rates. To combat that, New England aggressively stocked hatchery-raised salmon in rivers for decades, but low return counts and budget cutbacks eliminated many of those programs. Yearling Atlantic salmon at about the right size for stocking. Salmon live in fresh water for the first one to four years of life. Photo by Peter E. Steenstrta for USFWS In Connecticut a paired-down salmon stocking program remains. WNPR's Patrick Skahill recently met up with some fish stockers on Connecticut’s Farmington River, and brings us an audio postcard. About NEXT NEXT is produced at WNPR.

Lovely early fall weather means we’re spending our whole hour-long episode outside. All these sunny days, though, mean a shortage of water for crops, gardens, livestock, and lawns. Climate scientists warn that droughts interspersed with periods of heavy storms are becoming the new normal in New England. We look into how farmers and the rest of us are adapting. We also consider what “national monument status” means. President Barack Obama just granted the status to nearly 90,000 acres of the north woods of Maine, and is considering doing the same for miles of ocean canyons and mountains off the coast of Cape Cod. And: it's back to school time, but that means something different for the children of seasonal workers, bringing in the late summer crops. Our Dry New England Summer Livestock farmer Bill Fosher with sheepdog Zues. (Courtesy Bill Fosher) It was an unusually dry summer for much of New England. Massachusetts was (and still is) the hardest-hit. This week, Governor Charlie Baker announced an emergency loan fund to help family farms and other small businesses affected by the drought. New England Public Radio reporter Jill Kaufman has been reporting on the tentative move among New England farmers to adopt drought-friendly techniques. She joins us in the studio, and we call New Hampshire livestock farmer Bill Fosher to talk soil and water. It's not just farmers who have been affected by the long dry spell. If you live in Massachusetts, your town may have told you to limit watering the lawns and garden. But as WBUR reporter Shannon Dooling found out, the rules may be different on the other side of the town line. (Courtesy of the Massachusetts Department of Environmental Protection) Director of the Billerica Public Works Abdul Alkhatib points out the level of the Concord River is three feet lower than it was this time last year in 2015 due to the current drought conditions this summer. (Jesse Costa/WBUR) Monuments to Nature If you've ever visited the North Maine Woods, you know that it's one of the most wild places you'll ever see. Nearly 90,000 acres adjacent to Baxter State Park have been designated by President Obama as the Katahdin Woods and Waters National Monument. It’s not quite a national park, but it is protected recreational land. It was donated by Roxanne Quimby, the founder of personal care company Burt's Bees. The donation was her family's plan for some time. The moon rises over Mt. Katahdin. (Bill Duffy) Bull moose in the area designated Katahdin Woods and Waters National Monument (Mark Picard) View from Lunksoos Mountain (Bill Duffy) Wassataquoik River at Orion Falls (Credit: EPI) The area also has logging and paper industry history. Many politicians have fought against the protected designation, hoping that some day paper mills would return. We speak with two Maine reporters covering the dispute: Maine Public Broadcasting’s Susan Sharon, and Nick Sambides, Jr. of the Bangor Daily News. There's an even more remote part of New England being considered as a national monument. The New England Coral Canyons and Seamounts area, about 150 miles from Cape Cod, is (according to a Congressional letter written to the President): “a world of canyons that rivals the Grand Canyon in size and scale and underwater mountains that are higher than any east of the Rockies. These mountains – known as seamounts – rise as high as 7,700 feet from the ocean floor and are the only seamounts in the U.S. Atlantic Ocean.” A Paramuricea coral in Nygren Canyon, which is 165 nautical miles southeast of Cape Cod, Massachusetts. Hydromedusa in Washington Canyon. Mussels in Nygren Canyon. Lawmakers, led by Connecticut Senator Richard Blumenthal, want the president to use the 1906 Antiquities Act to preserve the area. This is much like President George W. Bush did when he designated a similar monument in 2006 off the coast of Hawaii. President Obama just expanded that monument. But like loggers in Maine, many in the commercial fishing industry are fighting the designation, questioning the use of the act by the president. We speak with Brad Sewell, Director of Fisheries and Atlantic Ocean Program at the Natural Resources Defense Council, which is backing the proposal. We also hear from Bob Vanasse, executive director of the fisheries industry group Saving Seafood. Maine’s Blueberry Harvest School September means one thing for most kids in New England: an end to summer holidays and the start of classes. But for some, the school year isn't that straightforward, because their parents chase the seasons from Texas to Maine, harvesting vegetables, picking apples, and raking blueberries. The federally funded Migrant Education Program seeks to fill some of the gaps left by a life on the road. MPBN reporter Jennifer Mitchell spent a day with the Blueberry Harvest School in Downeast Maine. The Blueberry Harvest School was established to teach kids whose parents are busy bringing in Maine's $75 million wild blueberry harvest. (Jennifer Mitchel/MPBN) To learn more about parents of these kids — the blueberry harvest workers — we spoke with Jorge Acero, State Monitor Advocate for migrant farm workers in Maine.

Prof. Peter Auster, Senior Research Scientist at Mystic Aquarium and Research Professor Emeritus at the University of Connecticut. The #coral canyons and #seamounts just 150 miles off the coast of New England are in need of protection

California Seamount Coalition director, Samantha Murray shares the latest campaign to add protections to significant seafloor features off the California coast. Also, in later August the E/V Nautilus will be exploring in the Greater Farallones NMS deploying its deep sea ROV's in deep sea coral habitats and shipwreck regions. Learn how everyone can explore real time via telepresence. Also learn about some coastal maritime archeology efforts happening along the Sonoma coast at Fort Ross Historic Park.

Plate tectonics and ocean bathymetry are discussed. Bathymetry is the study of ocean depth, which is affected in some regions by plate tectonics and mantle dynamics. Mid-ocean ridges are formed at plate boundaries where mantle material is rising to the ocean crust and solidifying as it cools to form new ocean crust material. Seamounts are volcanoes that have formed from molten mantle material pushing up through the ocean crust, but these volcanoes lie below sea level. These features are measured using acoustic depth profiling. Ocean water properties, such as temperature and salinity, as well as the methods used to measure them are also discussed. Complete course materials are available at the Open Yale Courses website: http://oyc.yale.edu This course was recorded in Fall 2011.

This week, we revisit a May 2010 interview with marine biologist Peter Etnoyer. Etnoyer and colleagues published a study last year that found that seamounts -- underwater mountains formed by volcanic activity -- may collectively form one of the largest habitats on Earth, encompassing more of the planet's surface than South America.

A new report finds that seamounts -- underwater mountains formed by volcanic activity -- may collectively form one of the largest habitats on Earth, encompassing more of the planet's surface than South America. We talk with NOAA's Dr. Peter Etnoyer, lead author of the new study.
