Genetic Evidence Points to Rapid, Large-Scale Northward Shift of Pacific Cod During Recent Climate Changes

October 10, 2019 — The following was released by NOAA Fisheries:

New genetic research suggests that unprecedented summer abundances of Pacific cod in the northern Bering Sea were due to escalating movement from their core habitat under recent warm conditions.

Until recently, Pacific cod were rarely encountered in the northern Bering Sea. Fishery surveys in the 1970s reported “trace amounts” of cod there. A 2010 Alaska Fisheries Science Center survey estimated that the entire northern population amounted to about 3% of the large southeastern Bering Sea stock that supported a valuable commercial fishery.

Then in 2017, the summer survey recorded dramatically higher abundances in the north: a 900-fold increase since 2010. In the same year, southeastern Bering Sea abundances were down 37% from 2016. Strikingly, the increase in the north nearly matched the decrease in the southeastern Bering Sea.

A 2018 survey revealed an even more remarkable shift: there were more cod in the northern than southeastern Bering Sea.

URI researchers awarded multiple grants to study aspects of aquaculture industry

October 10, 2019 — Several scientists at the University of Rhode Island have been awarded grants to study oyster genetics, breeding and diseases as part of a region-wide effort to support the growing oyster aquaculture industry in the Northeast and assist efforts to restore wild oyster populations.

“Wild and farmed oysters are facing major threats from water quality and disease,” said Marta Gomez-Chiarri, a URI professor of animal science who has studied oyster diseases in Narragansett Bay for more than 20 years. “Even though local water quality has improved in Rhode Island, oysters across the United States face localized threats from pollution and eutrophication while at the same time dealing with multiple factors of global ocean change, like ocean acidification, as well as changes in salinity and dissolved oxygen. We are only beginning to understand the effects of these multiple stressors.”

Gomez-Chiarri — along with URI Assistant Professor Jonathan Puritz and U.S. Department of Agriculture scientist Dina Proestou — have teamed with shellfish geneticists and breeders from 10 other East Coast universities to form the Eastern Oyster Genome Consortium to develop genetic tools to accelerate selective breeding efforts. The consortium, in a proposal led by Rutgers University, has been awarded a $4.4 million grant from the Atlantic States Marine Fisheries Commission to accelerate the pace of identifying the genes responsible for desirable traits like disease resistance.

Record low Gulf Coast supply could jolt oyster prices

October 10, 2019 — This spring’s record-shattering flooding from the Mississippi River has wreaked historic havoc on oyster production in the Gulf of Mexico, which could reverberate for years to come with scant supply and hard-to-digest prices.

Louisiana, which bore the worst of the damage from too-low salinity and smothering algae blooms and historically accounts for 75 percent of Gulf harvests and 34 percent of U.S. harvests, is all but out of commission for this fall’s oyster harvest season.

The next big California vs. Trump fight is over water and endangered species

October 7, 2019 — Just how far will California Gov. Gavin Newsom go in his high-profile fight with the Trump administration over environmental protections?

The next few months will provide an answer, as Newsom is forced to take a stand on Trump rollbacks in a long-contested battleground—the Northern California  that helps supply more than half the state’s population with drinking  and fills irrigation canals on millions of acres of farmland.

The battle lines are not nearly as clearly drawn as they are on climate change or air pollution, where the state is presenting a fairly unified front against Washington. When it comes to California water, there is no unity.

Some of the state’s biggest and most powerful water agencies are eager for the  to weaken endangered species protections that have cut their delta deliveries. And they want the Newsom administration to go along.

MASSACHUSETTS: Lobsters, fish fall victim to low oxygen levels in Cape Cod Bay

October 4, 2019 — Two weeks ago, lobstermen working off Scorton Creek started seeing something they had never experienced. Lobsters, in fact everything in their traps, were coming up dead.

Massachusetts Division of Marine Fisheries senior biologist Robert Glenn started fielding phone calls from puzzled fishermen Sept. 23. The fishermen were worried there might be something in the water that was killing the lobsters, fish, shellfish, even sea worms.

It turns out, it was something missing from the water: oxygen.

For the past two weeks, division researchers and scientists from the Center for Coastal Studies in Provincetown have boarded vessels and taken water samples, gathered temperature data at various depths and measured the amount of oxygen dissolved in the water. Preliminary results from testing on dozens of dead lobsters found nothing toxic in the water that could have killed them, and the focus was on a phenomenon that occurs every year — low oxygen in the layer of water along the ocean bottom, Glenn said.

West Coast Rockfish Boom with the Blob

October 4, 2019 — The following was released by NOAA Fisheries:

The high temperatures that came with the marine heatwave known as the Blob led to unprecedented mixing of local and subtropical species. There were, often with new and unpredictable outcomes. Out of that mix came one unexpected winner: West Coast rockfish. These bottom-dwelling species, which that had previously collapsed in the face of overfishing during the 2000s, thrived under the new conditions.

Scientists from Oregon State University and NOAA Fisheries’ Northwest Fisheries Science Center recount the boom in young rockfish in a new research paper in the journal Fisheries. It examines the effects of the Blob as documented by NOAA Fisheries offshore surveys. Scientists have been conducting the surveys for more than 20 years. The Blob years brought some of the most dramatic changes in marine life off the West Coast they’ve ever seen.

Unexpected interactions may have also altered the abundance of some species, from plankton that support the food web to fish that depend on them, the researchers wrote.

In the waning months of the Blob in 2016, juvenile rockfish increased over a large area from California to Alaska. Since juvenile rockfish are very difficult to distinguish from one another, scientists could not tell which species benefited. They could not tell what specifically drove the boom in their numbers and or whether they will support fisheries in future years.

NEW YORK: Press Sessions In East Hampton Focuses On The Future Of Wind Farms

October 3, 2019 — Offshore wind farms have been pitched as a critical cog in the drive to reduce the use of fossil fuels to power American life, while trying to fend off the worst effects of climate change.

But will the environmental and economic problems the construction and operation of the giant wind turbines cause be outweighed by the long-term benefits? And are state and federal regulators, or the wind farm developers themselves, doing enough to offset or protect against those problems?

These were the questions put to the panel of experts at the first “Press Session” event held in East Hampton last Thursday afternoon, September 26, at Rowdy Hall. Representatives of the fishing and offshore wind industry, environmental and renewable energy advocates, and local government officials each shared their perspective.

Last week’s Press Session panel included Dr. Francine Kershaw, a large marine mammals expert with the Natural Resources Defense Council; Bonnie Brady, a commercial fishing advocate; Gordian Raacke, a renewable energy advocate; Jennifer Garvey, Long Island development coordinator for Ørsted, the company proposing to build the South Fork Wind Farm; East Hampton Town Councilwoman Sylvia Overby; and State Assemblyman Fred W. Thiele Jr.

IPCC Report Projects “Unprecedented” Changes in Ocean, Cryosphere Due to Global Warming

October, 2, 2019 — The 51st session of the Intergovernmental Panel on Climate Change (IPCC 51) adopted the Summary for Policymakers (SPM) of the Special Report on the Ocean and Cryosphere in a Changing Climate (SROCC), and accepted the underlying report. The SROCC assesses the latest scientific knowledge about the physical science basis for, and impacts of, climate change on ocean, coastal, polar and mountain ecosystems, and the human communities that depend on them.

The report also evaluates their vulnerabilities and adaptation capacity, as well as options for achieving climate-resilient development pathways. The report’s SPM, which the Panel approved line-by-line, aims to tease out some of the key findings of the longer report in such a way that policymakers can easily comprehend and use them.

The Earth Negotiations Bulletin highlights that oceans and ice are an “integral and dynamic part of the earth’s climate systems,” as they cover more than 80% of the earth’s surface. The report underscores the urgency of prioritizing “timely, ambitious and coordinated action” to address “unprecedented” and enduring changes in the ocean and cryosphere. It also describes the benefits of ambitious and effective adaptation for sustainable development, and the escalating costs and risks of delayed action.

According to the report, global warming has already reached 1°C above preindustrial levels, with: profound consequences for ecosystems and people; a warmer, more acidic and less productive ocean; melting glaciers and ice sheets causing increased sea level rise; and coastal extreme events becoming more severe.

The global ocean, the report notes, has warmed unabated since 1970 and has taken up more than 90% of the excess heat in the climate system, with consequences now visible in increased ocean acidification, stratification and loss of oxygen. Speaking at the press conference that launched the report to the public, IPCC Vice-Chair Ko Barrett said, “Water is the lifeblood of the planet,” and the world’s ocean and cryosphere have been “taking the heat” from climate change for decades, with “sweeping and severe” consequences for nature and humanity. She warned that changes to the ocean and cryosphere are forcing people from low-lying coastal cities to Arctic communities to “fundamentally alter their ways of life.”

NOAA awards $10.2 million for harmful algal bloom research

October 2, 2019 — The following was released by NOAA:

NOAA will fund 12 new research projects around the country to better understand and predict harmful algal blooms (HABs) and improve our collective response to them.

NOAA’s National Centers for Coastal Ocean Science (NCCOS) is allocating $10.2 million in FY 2019 to fund HAB research across the nation. Approximately $8.4 million of that will cover the first year of new 3- to 5-year projects, and $1.78 million will go to 3-year projects already in process. Funded under NOAA’s ECOHAB and MERHAB programs, new projects will begin in Alaska, California, Chesapeake Bay, Florida, the Great Lakes, New England and the Pacific Northwest. A full list of the new grant awards is available online.

Award recipients will conduct research to identify conditions that increase bloom toxicity; model toxin movement from the water into shellfish, fish and marine mammals; and improve toxin monitoring and forecasts. NCCOS research programs help states and regions around the nation mitigate the effects of HABs, which can include contaminated drinking water, fisheries closures and disruption to recreation and tourism.
