Green sand threatens Biden’s offshore wind ambition

June 25, 2024 — A green mineral scattered along the Atlantic Ocean’s seafloor is the latest hurdle for President Joe Biden’s plan to jump-start the offshore wind industry.

Glauconite is sediment that resembles the green sand in a fish tank. But if pounded by pile drivers, it shatters to form a claylike layer.

Monopiles — hollow steel tubes driven deep into the seafloor to support turbine towers — often cannot be hammered through the thick paste, cutting off the cheapest and most widely preferred foundation for the first U.S. offshore wind farms.

“It’s almost like magic what happens when the monopile is driven through it,” said George Hagerman, an offshore wind expert at the Department of Energy’s National Renewable Energy Laboratory. “It all of a sudden becomes very, very, sticky, almost like plaster.”

Identified in several offshore wind lease areas in the north Atlantic, the mineral poses a growing hazard to offshore wind projects that already face high costs and razor thin margins. At least four wind lease areas off the coast of New England and New York — Beacon Wind, Empire Wind, New England Wind and Sunrise Wind — have all have grappled with glauconite.

The world’s oceans are off-the-charts warm — and the worst could be yet to come

July 31, 2023 — Scientists are running out of extreme adjectives to describe the state of the world’s oceans.

Global sea surface temperatures are spiking off the charts. The North Atlantic Ocean, in particular, has for months been engulfed in what scientists have said is an “unprecedented” marine heat wave. The Gulf of Mexico and Caribbean basin have also been unusually warm. The waters off the coast of Florida topped 100 degrees F multiple times this week — temperatures comparable to a hot tub.

What’s more, some scientists say the worst may be yet to come.

“We’re not even at the height of the summer,” said Svenja Ryan, a physical oceanographer at the Woods Hole Oceanographic Institution in Massachusetts. “Typically, the ocean continues to warm until September, so I think certainly we can expect this heat wave to last into the fall.”

This month, parts of the Caribbean Sea and Gulf of Mexico were more than 5 degrees F warmer than normal. In recent days, a patch of the North Atlantic off the coast of Newfoundland, Canada — a region normally kept relatively cool by the Labrador Current — was an astounding 9 degrees F warmer than usual, according to Frédéric Cyr, a research scientist at Fisheries and Oceans Canada, a department of the Canadian government that oversees marine science and policy and manages the country’s fisheries.

Vanishing whale’s decline worse than previously thought, feds say

July 18, 2023 — A review of the status of a vanishing species of whale found that the animal’s population is in worse shape than previously thought, federal ocean regulators said Monday.

The North Atlantic right whale numbers less than 350, and it has been declining in population for several years. The federal government declared the whale’s decline an “unusual mortality event,” which means an unexpected and significant die-off, in 2017.

The National Oceanic and Atmospheric Administration released new data that 114 of the whales have been documented as dead, seriously injured or sub-lethally injured or sick since the start of the mortality event. That is an increase of 16 whales since the previous estimate released earlier this year.

Scientists see stronger evidence of slowing Atlantic Ocean circulation, an ‘Achilles’ heel’ of the climate

February 26, 2021 — A growing body of evidence suggests that a massive change is underway in the sensitive circulation system of the Atlantic Ocean, a group of scientists said Thursday.

The Atlantic meridional overturning circulation (AMOC), a system of currents that includes the Florida Current and the Gulf Stream, is now “in its weakest state in over a millennium,” these experts say. This has implications for everything from the climate of Europe to the rates of sea-level rise along the U.S. East Coast.

Although evidence of the system’s weakening has been published before, the new research cites 11 sources of “proxy” evidence of the circulation’s strength, including clues hidden in seafloor mud as well as patterns of ocean temperatures. The enormous flow has been directly measured only since 2004, too short a period to definitively establish a trend, which makes these indirect measures critical for understanding its behavior.

The new research applies a statistical analysis to show that those measures are in sync and that nine out of 11 show a clear trend.

Prior research had suggested that the AMOC was at its weakest point in a millennium or more, and suggested a roughly 15 percent weakening since about 1950. But when it comes to the latest evidence, “I think it just makes this conclusion considerably stronger,” said Stefan Rahmstorf, an author of the research and an oceanographer with the Potsdam Institute for Climate Impact Research in Germany.

The study was published in Nature Geoscience by scientists from the Potsdam Institute, Ireland’s Maynooth University and University College London.

The AMOC is driven by two vital components of ocean water: temperature and salt. In the North Atlantic, warm, salty water flows northward off the U.S. coastline, carrying heat from the tropics. But as it reaches the middle latitudes, it cools, and around Greenland, the cooling and the saltiness create enough density that the water begins to sink deep beneath the surface.

Offshore drilling plans postponed, including off Georgia coast

April 26, 2019 — The Trump administration is suspending plans to expand offshore drilling, including plans to drill off Georgia after a recent court ruling blocked drilling in the Arctic and Atlantic, Interior Secretary David Bernhardt told the Wall Street Journal.

Bernhardt said the agency would delay indefinitely its five-year plan for oil and gas drilling on the Outer Continental Shelf as the case goes through the appeals process.

“By the time the court rules, that may be discombobulating to our plan,” Bernhardt told the Wall Street Journal in a report published Thursday. The plans had been expected to be released in the near future.

Hearings on Plan to Protect Spawning Fish off New England

February 25, 2019 –Interstate fishing regulators are holding hearings on the East Coast about a plan to protect herring off of New England when the fish are spawning.

Herring are among the most important fish in the Atlantic Ocean because of their role in the food chain and commercial value. The Atlantic States Marine Fisheries Commission’s considering measures designed to protect spawning herring in the inshore Gulf of Maine.

NEW JERSEY: LoBiondo joins bipartisan group opposing Atlantic Ocean seismic testing

December 10, 2018 — U.S. Rep. Frank LoBiondo has joined 92 other House members from both parties in opposing the Trump administration’s decision to allow seismic airgun blasting in the Atlantic Ocean.

Critics say the constant barrage of compressed air blasts used to find gas and oil deposits under the sea floor harms marine mammals and other sea life.

LoBiondo, R-2nd, said Friday he had signed a letter sent to Commerce Secretary Wilbur Ross and Interior Secretary Ryan Zinke, asking them not to issue final permits.

“Seismic testing is a prelude to drilling for oil and natural gas,” said LoBiondo, a longtime foe of drilling in the Atlantic.

ICCAT: BIGEYE IN THE CROSS-HAIRS

November 12, 2018 — Fisheries representatives and environmental activists from around the globe will convene through November 19 for the 21st Special Meeting of the International Commission for the Conservation of Atlantic Tunas (ICCAT) in Dubrovnik, Croatia.

An international treaty organization, ICCAT is responsible for the conservation and management of tuna and tuna-like pelagic species (tuna, marlin, sharks, swordfish, etc.) found in the Atlantic Ocean.

Of all the discussion, debate and deliberation this week by the participating ICCAT nations, bigeye tuna decisions will have the biggest impact on Northeast canyon fishermen next season.

Based on a recent ICCAT scientific report, bigeye tuna is currently considered overfished and subject to overfishing. The major issue however is that the current international harvest cap of 65,000 tons set by ICCAT has been exceeded by approximately 20 thousand tons.

Fisheries nations to decide fate of declining bigeye tuna

October 1, 2018 — PARIS — Dozens of nations with commercial fisheries in the Atlantic Ocean will grapple next week with a new finding that bigeye tuna, the backbone of a billion dollar business, is severely depleted and overfished.

Unless catch levels are sharply reduced, scientists warned, stocks of the fatty, fast-swimming predator could crash within a decade or two.

Less iconic than Atlantic bluefin but more valuable as an industry, bigeye (Thunnus obesus) — one of several so-called tropical tunas — is prized for sashimi in Japan and canned for supermarket sales worldwide. It is not farmed.

An internal report by 40-odd scientists working under the inter-governmental International Commission for the Conservation of Atlantic Tunas (ICCAT), finalized last week, shows that populations have fallen to less than 20 percent of their historic levels.

Even more critical, the stock is barely half the size needed to support a “maximum sustainable yield” — the largest catch that can be taken without compromising long-term stability of the species.

Current harvests, overwhelmingly legal, are also more than 60 percent above levels that would give bigeye at least a fighting chance of recovering its numbers, the report said.

A controversial comeback for a highly prized tuna

August 29, 2018 — SOUTH PORTLAND, Maine — On a drizzling summer afternoon in South Portland, marine biologist Walt Golet is helping attach a quarter-ton Atlantic bluefin tuna to a heavy crane so it can be weighed as part of New England’s premier tournament for the giant fish. And this year’s derby is different than many in the past — there are far more tuna.

A decade ago, participants in the Sturdivant Island Tuna Tournament went consecutive years in which they didn’t catch a single fish in the Gulf of Maine. This year, fishermen set a record with 30, including the 801-pound (363.33-kilogram) winner.

Their record haul is happening amid a turning point for these giant tuna, an iconic species that scientists say appears to be slowly recovering in the Atlantic Ocean. The reemergence of bluefin, which can weigh more than half a ton, has led to debate among fishermen, conservationists and scientists over just how much the big fish have recovered. It remains at a fraction of its population 60 years ago.

“There’s probably no fish that’s ever been more politicized than Atlantic bluefin tuna,” said Golet, a University of Maine professor. “People get a passion for this fish. And people are making a living off of this fish.”

The fish have long been at the center of a battle among commercial fishermen who can make a huge amount of money on a single fish, environmentalists who see them as marvels of marine migration, and consumers who pay a hefty price for them in restaurants.
