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.

State of Tuna Stocks Worldwide Assessed in Comprehensive ISSF Report

Global tuna catch stays at 78% healthy level

March 8, 2018 — WASHINGTON — The following was released by the International Seafood Sustainability Foundation:

Of the total tuna catch in 2016, 78% came from stocks at “healthy” levels, unchanged since last reported, according to a February 2018 International Seafood Sustainability Foundation (ISSF) Status of the Stocks report. Skipjack tuna stocks — at healthy levels in all ocean regions — constituted more than one-half of the 2016 total catch.

One notable change in stock status in the February 2018 Status report is for Southern bluefin tuna, a stock that has moved from orange to yellow in abundance ratings. Stock abundance is low, about 13% of the unfished level. However, the stock is rebuilding continuously as a result of the implementation of a robust Management Procedure (a Harvest Strategy) by the Commission for the Conservation of Southern Bluefin Tuna, the regional organization in charge of managing the stock. In contrast, the Pacific bluefin stock, along with the Indian Ocean yellowfin stock and the Atlantic Ocean bigeye stock remain overfished. See Tables 1 and 2 in the report for specific rating changes.

There were no dramatic changes in tuna stock status since the previous November 2017 Status report; the updated report reflects new data made available at late 2017 tuna Regional Fisheries Management Organization (RFMO) meetings.

Updated several times per year, Status of the Stocks assigns color ratings (green, yellow or orange) on stock heath, stock management, and ecosystem impact. The report ranks the 23 stocks of major commercial tunas around the world using a consistent methodology.

Key Statistics in the Report

  • Total catch: In 2016, the total major commercial tuna catch was 4.9 million tonnes, a 2% increase from 2015. More than half of the total catch (57%) was skipjack tuna, followed by yellowfin (30%), bigeye (8%) and albacore (4%). Bluefin tunas (3 species) accounted for only 1% of the global catch. These percentages changed only slightly from the Nov. 2017 reporting period. 
  • Abundance or “spawning biomass” levels: Globally, 57% of the 23 stocks are at a healthy level of abundance, 13% are overfished, and 30% are at an intermediate level.
  • Stocks receiving orange scores, indicating overfished status, include Atlantic Ocean bigeye, Pacific Ocean bluefin and Indian Ocean yellowfin.
  • Fishing mortality levels: 65% of the 23 stocks are experiencing a well-managed fishing mortality rate, and 13% are experiencing overfishing (with no change from the previous report).
  • Largest catches by stock: The three largest catches in tonnes are Western Pacific Ocean skipjack, Western Pacific Ocean yellowfin, and Indian Ocean skipjack.
  • Tuna production by ocean region: Most (53%) of the world’s tuna is harvested from the Western and Central Pacific Ocean, followed by the Indian Ocean (20%), Eastern Pacific Ocean (13%), and Atlantic Ocean (10%).
  • Tuna production by fishing gear: 65% of the catch is made by purse seining, followed by longline (12%), pole-and-line (8%), gillnets (3%) and miscellaneous gears (12%). These percentages changed only slightly from the Nov. 2017 reporting period.

About the Report

There are 23 stocks of major commercial tuna species worldwide – 6 albacore, 4 bigeye, 4 bluefin, 5 skipjack, and 4 yellowfin stocks. The Status of the Stocks summarizes the results of the most recent scientific assessments of these stocks, as well as the current management measures adopted by the RFMOs. This report ranks the status and management of the 23 stocks using a consistent methodology based on three factors: Abundance, Exploitation/Management (fishing mortality) and Environmental Impact (bycatch).

ISSF produces two reports annually that seek to provide clarity about where we stand — and how much more needs to be done — to ensure the long-term sustainability of tuna stocks: the Status of the Stocks provides a comprehensive analysis of tuna stocks by species, and the Evaluation of the Sustainability of Global Tuna Stocks Relative to Marine Stewardship Council Criteria (MSC) provides scores for the stocks and RFMOs based on MSC assessment criteria. The MSC-certified fisheries list (Appendix 2) in Status of the Stocks complements the Evaluation report.

Together, these tools help to define the continuous improvement achieved, as well as the areas and issues that require more attention. Access the newly updated ISSF stock status ratings here.

 

East Coast of U.S. Emerging Into a Hotbed for Offshore Wind

February 7, 2018 — Atlantic coast states might be protesting President Trump’s plan to expand offshore oil drilling, but they’re increasingly embracing a different kind of seaborne energy: wind.

States bordering the outer continental shelf are looking for carbon-free electricity, even as the Trump administration rolls back rules requiring it.

Last week, New Jersey Gov. Phil Murphy (D) announced that his state will aim for 3,500 megawatts of installed offshore wind by 2030, enough to power 1 million homes. Massachusetts has a goal to build 1,600 MW of offshore wind power by 2027, and New York has committed to 2,400 MW by 2030.

At the same time, wind technology is quickly advancing, thanks to its popularity in Europe. Ten countries across Europe had deployed 12,600 MW of offshore wind power by the end of 2016. In the United States, the Interior Department’s Bureau of Ocean Energy Management (BOEM) has issued 13 wind energy leases off the Atlantic coast. In late 2016, the first offshore wind farm in the United States came online about 4 miles off the coast of Block Island, R.I.

It’s unclear how the growth in offshore wind might be affected by Trump’s plan to open nearly all U.S. waters to oil and gas drilling.

But there are hints that the two types of development could come into contact on the open water.

According to BOEM’s draft proposed 2019-24 offshore oil and gas leasing plan, any drilling off the Atlantic Seaboard would have to be “coordinated” with current and future offshore wind development. The agency predicts that more wind projects are likely to be built between 2019 and 2024, when oil and gas lease sales are slated to be held.

Experts said it’s unlikely there would be direct competition for the same slice of ocean between the two industries. But that’s a hard question to answer.

Kevin Book, managing director of research for ClearView Energy Partners LLC, said it’s too early to know how offshore wind and oil and gas development might interact off the East Coast. Historically, offshore wind has been a nascent industry, and no one has drilled for oil in the Atlantic for decades. It’s been so long that developers have little idea what type of oil reserves lie under the sea, or if oil companies will want to tap them.

Snow crab prices not melting any time soon

February 6, 2018 — The snow will eventually melt in the US state of Alaska and the Maritime provinces of Canada, but you better get used to the high prices of snow crab because they are sticking around for a while.

A global shortage of the species is expected to continue for a third straight year in 2018, thanks to a combination of reduced catches across North America and continuous demand in Asia, a panel of speakers suggested at a conference in Miami, Florida, last month.

There will be about 104,000 metric tons of snow crab available, down 10% from the more than 114,000t landed worldwide in 2017 and 76% below the 150,000t landed in 2015, based on data shared during a shellfish panel at the National Fisheries Institute’s Global Seafood Market Conference (GSMC).

The result: Five-to-eight ounce packages of legs and shoulders are selling for $8 per pound wholesale in the US.

It’s leading seafood dealers in the US to more often offer their clients less expensive substitutes.

Brian Cooper, a partner at Sea Trek Enterprises, an East Greenwich, Rhode Island-based importer of crab and scallops, told Undercurrent News that his company normally sells anywhere from 200 to 300 loads (1,000 cases each) of snow crab each year. But he’s skeptical about matching that number in 2018 and is increasingly promoting rock crab, a species most often found in Washington State’s Puget Sound. It’s popular in Asian markets.

“You can’t charge $20 for a buffet at a Chinese restaurant and put an $8 snow crab in there,” he said. “That’s not going to work.”

Lobster, shrimp, or even chicken and beef could also be used as replacements on menus, said one large seafood restaurant executive at the GSMC event.

“It’s easier to take things off a menu than to put them back on,” he added.
