Global Deals to Save Oceans Were In Reach. Then Covid-19 Hit

June 9, 2020 — Before 2020 became the year of Covid-19, it was set to be the “year of the oceans.”

With only a small portion of them protected by law or agreement, expectations were high that bold steps to preserve biodiversity, rein in overfishing and bolster social responsibility were within reach. Then the coronavirus arrived, and high-profile meetings from the High Seas Treaty (the first global agreement to police and manage international waters) to the United Nations Climate Change Conference were postponed.

The oceans are critical to any effort to slow global warming. Delay in global agreements, given how little time is left to avoid catastrophe, has only made matters that much more desperate.

Waters more than 200 nautical miles from national shores are of critical importance to both fisheries and climate mitigation. The Global Ocean Commission estimates the high seas account for up to $16 billion in annual gross catch and between $74 billion and $222 billion in annual carbon storage. As the world struggles to cut emissions to zero by 2050—a goal scientists say is required to avoid massive planetary shifts—the ocean’s ability to store CO₂ will increasingly diminish, according to new research published last week in the journal AGU Advances.

Study: Marine heat waves will decimate fish at twice the rate climatologists previously predicted

June 9, 2020 — Over the last decade, two massive marine heatwaves, better known as “blobs” swept the North Pacific Ocean, raising surface temperatures more than 5 degrees Fahrenheit causing blooms of toxic algae and major die-offs in the ecosystem. A new study from the University of British Columbia reports that as these heatwaves continue, they may have far more devastating implications to fisheries than previously predicted.

Climate scientists have known for years that global warming would have devastating long-term impacts on marine species. Already, fast-melting Bering Sea ice is threatening spotted seals and other marine mammals. Warming Gulf of Alaska waters wiped out cod eggs in 2019, causing a crash in cod stocks. Record warm waters in the Yukon River last summer killed thousands of migrating salmon with heat stress.

While climate change is steadily warming oceans all over the world, marine heatwaves, like the two North Pacific “Blobs,” are causing more dramatic swings in surface temperatures. In 2014 and again in 2019, ocean temperatures in Alaska rose as much as 5 degrees Fahrenheit.

Gulf ‘dead zone’ costing seafood industry, environment $2.4 billion in damage each year, study says

June 9, 2020 — The massive “dead zone” in the Gulf of Mexico is causing up to $2.4 billion dollars in damage to fisheries and marine habitat every year, a new report says.

Covering an area about the size of New Hampshire, the 6,700-square-mile zone of low dissolved oxygen has long been the bane of shrimpers and other fishers off the coasts of Louisiana and eastern Texas. A report released this month from the Union of Concerned Scientists offers the first comprehensive assessment of the dead zone’s economic impact, and warns the root problem — agricultural pollution from the Mississippi River — is likely to grow in severity as the world’s climate changes.

“Gulf Coast communities know that the dead zone impacts their livelihoods, but research has never put a dollar value on its damage to the fishing industry,” said Rebecca Boehm, a UCS economist and the report’s author. “This study quantifies both the amount of nitrogen flowing to the Gulf from farms upstream, and the toll it is taking economically on the foundation of the Gulf fishing industry.”

As NOAA predicts larger than average Gulf dead zone, study reveals billions in damage to fish stocks

June 5, 2020 — NOAA scientists announced on 3 June that the forecast for the Gulf of Mexico hypoxic area, more commonly referred to as the “dead zone,” will be larger than average in 2020.

The current forecast of the dead zone – an area of low to no oxygen that can kill fish and other marine life – predicts an area of roughly 6,700 square miles, which is larger than the recent average measured size of the dead zone of 5,387 square miles. For comparison, 6,700 square miles is roughly the size of the U.S. states of Rhode Island and Connecticut combined.

Lobsters and Sea Scallops Moving Out of Southern N.E.

June 5, 2020 — Researchers have projected significant changes in the habitat of commercially important American lobster and sea scallops along the Northeast continental shelf. They used a suite of models to estimate how species will react as waters warm. The researchers suggest that American lobster will move further offshore and sea scallops will shift to the north in the coming decades.

The study’s findings were published recently in Diversity and Distributions. They pose fishery management challenges as the changes can move stocks into and out of fixed management areas. Habitats within current management areas will also experience changes — some will show species increases, others decreases, and others will experience no change.

“Changes in stock distribution affect where fish and shellfish can be caught and who has access to them over time,” said Vincent Saba, a fishery biologist in the Ecosystems Dynamics and Assessment Branch at the Northeast Fisheries Science Center and a co-author of the study. “American lobster and sea scallop are two of the most economically valuable single-species fisheries in the entire United States. They are also important to the economic and cultural well-being of coastal communities in the Northeast. Any changes to their distribution and abundance will have major impacts.”

Saba and colleagues used a group of species distribution models and a high-resolution global climate model. They projected the possible impact of climate change on suitable habitat for the two species in the large Northeast continental shelf marine ecosystem. This ecosystem includes waters of the Gulf of Maine, Georges Bank, the Mid-Atlantic Bight, and southern New England.

Researchers predict warming Atlantic will push lobsters offshore, scallops northward

June 4, 2020 — East Coast sea scallop stocks will likely follow lobsters in shifting away from rich Mid-Atlantic and southern New England grounds in the coming decades as a consequence of warming ocean waters, according to a new study that projects the impact of climate change on the two richest Atlantic fisheries.

Researchers used species distribution models and a high-resolution global climate model to picture the possible impact of climate change on habitat for lobsters and scallops in the Northeast continental shelf ecosystem, ranging from the New York Bight north to southern New England, Georges Bank and the Gulf of Maine.

Their findings, recently published in the journal Diversity and Distributions, suggest that over the coming 80 years both lobsters and scallops will be shifting northward, and lobsters also moving into deeper Gulf of Maine waters.

The researchers note that the latest benchmark assessment of the lobster stock, cited by the Atlantic States Marine Fisheries Commission in 2015, showed the stock in the southern Mid-Atlantic range was already severely depleted due to several environmental factors including recruitment failure and shell disease related to warmer waters.
