NOAA scientists set sail on landmark West Coast Ocean Acidification survey

July 21, 2026 — The following was released by the Pacific Marine Environmental Laboratory, National Oceanic and Atmospheric Administration:

On July 20, 2026, researchers embarked on the NOAA Ocean Acidification Program’s West Coast Ocean Acidification mission (WCOA 2026). Departing from San Diego aboard the University of Alaska, Fairbanks (R/V) Sikuliaq, the team will travel north to Washington, adding important new observations to NOAA’s long-term monitoring of ocean acidification and its impacts on marine resources.

WCOA 2026 will couple ocean chemistry, biology, and physics to build a more comprehensive view of how extreme events impact biogeochemistry and ecosystems.

“Results from past WCOA cruises have provided novel insights into acidification rates and impacts in coastal and estuary habitats that provide our nation with rich fish and shellfish resources,” said Dr. Simone Alin, Supervisory Oceanographer, NOAA/PMEL. Resource managers and harvesters can use this information to inform fisheries management decisions.

This intensive 30-day coastal research cruise aboard the 261-foot research vessel offers scientists a unique opportunity of sampling during an El Niño that is on track to become one of the strongest on record. El Niño brings warmer water and can alter upwelling and precipitation patterns in the region. Phytoplankton and zooplankton communities will follow these warmer waters, which impacts food webs and fisheries as seen during past marine heatwaves.

Two days after the Sikuliaq departs, the PMEL SeaTrac will head south from Washington to collect added coastal measurements during peak ocean acidification and hypoxia season and pick up any El Niño signal that may have made to the northern California Current System this summer. These OA cruises provide critical high-quality data for the U.S. Coastal Large Marine Ecosystems, and are essential for modeling and forecasting changes in ocean acidification and hypoxia to better prepare for future impacts to valued fisheries and ecosystems.

Led by researchers at the University of Washington’s Cooperative Institute for Climate, Ocean, & Ecosystem Studies and PMEL, researchers will collect high-quality ocean chemistry data, phytoplankton, zooplankton, and other observations. Scientists will also collect environmental DNA, which can reveal the diversity and abundance of ocean life in different ocean conditions.

Data collected during WCOA 2026 are essential for validating models and forecasts of ocean conditions like J-SCOPE. This short term (six to nine month) forecast is used for the California Current Integrated Ecosystem Assessment. High quality ocean carbon chemistry data is required to forecast the saturation state of calcium carbonate, the mineral building block used by shellfish like Dungeness crabs, clams, and oysters.

Other coordinated regular coastal fisheries surveys, including the California Cooperative Oceanic Fisheries Investigations (CalCOFI) enhance the impact of WCOA 2026. By conducting biological net tows at established stations, researchers will gain high-quality data on marine life.

Ultimately, the data collected through WCOA 2026 will serve as a foundational benchmark for monitoring, modeling and research in the region. These data will provide calibration information for sensor networks designed to fill measurement gaps between research cruises. With the potential for sampling to occur as ocean conditions change with El Niño, NOAA and our partners will be able to better understand how extreme conditions alter vital marine resources like Dungeness crabs, krill, plankton and other fisheries.

MAINE: Hard-shell clam project aims to diversify aquaculture and shellfish harvesting in Maine

January 5, 2026 — An effort to diversify Maine’s aquaculture and shellfish industries is getting a boost from a hard shell clam farming project near Brunswick.

The project, led by the conservation science group Manomet, involved seeding some 400,000 quahogs in floating upweller systems that are commonly used in oyster farming, said senior fisheries director Marissa McMahan.

Gulf of Maine sees rising pH, defying expectations of increasing ocean acidity

July 31, 2025 — The Gulf of Maine—home to commercial fisheries for oysters, clams and mussels—has unexpectedly avoided an increase in seawater acidity, helping to preserve the health of its fisheries.

“Contrary to expectation,” a team of scientists wrote in a paper published in the journal Scientific Reports, we … find that pH has increased (+ 0.2 pH units) over the past 40 years, despite concurrent rising atmospheric CO2.” (Determining the decades-long trend required measurements of boron isotopes within annual skeletal bands built by crustose coralline algae. More about that later.)

The Gulf’s acidity levels are unexpected because atmospheric levels of  continue to climb. And because carbon dioxide is absorbed faster and easier into , the frigid waters of the Gulf would be expected to take in more carbon. More carbon in water generally lowers pH and increases acidity.

“One goes down and the other goes up,” said Alan Wanamaker, an Iowa State University professor of earth, atmosphere, and climate and a paper co-author. “That’s what we’ve seen in the .”

New study paints gloomy picture of climate change’s impact on commercial fishing

April 22, 2025 — A new study of some of California’s most commercially significant aquatic species paints a grim picture for the future of the state’s fishing industry under the growing threat of climate change.

The study, compiled by a host of researchers including federal and state scientists as well as researchers from UC Santa Cruz and UC Davis, looked at 34 aquatic species in an attempt to gauge how each would fare under predicted climate change scenarios.

Among the species studied were Dungeness crab, red abalone, Pacific herring, Pismo clams, pink shrimp, Pacific bonito and California spiny lobster. The group ranked each by their level of vulnerability to changing environmental conditions.

“The most striking thing that we found is that among the species that were ranked as the most highly vulnerable happened to also be some of California’s economically valuable and culturally important species,” said Mikaela Provost, assistant professor of fisheries ecology at UC Davis and co-author of the study.

California’s oceans are highly productive due to seasonal upwelling which keeps water temperatures cool and filled with nutrients. But models of future conditions forecast disruption through rising temperatures, deoxygenation and potential changes in circulation.

Offshore wind farms expected to reduce clam fishery revenue, study finds

June 23, 2022 — An important East Coast shellfish industry is projected to suffer revenue losses as offshore wind energy develops along the U.S. Northeast and Mid-Atlantic coasts, according to two Rutgers studies.

The studies, which appear in the ICES Journal of Marine Science, examined how offshore wind farms planned for the eastern United States could disrupt fishing of the Atlantic surfclam, a major economic driver from Virginia to Massachusetts that generates more than $30 million in direct annual revenue. Total fleet revenue declines measured by the studies ranged from 3 percent to 15 percent, depending on the scale of offshore wind development and response of the fishing fleet.

In New Jersey, losses could be as high as 25 percent for  based in Atlantic City.

“Understanding the impacts of fishery exclusion and fishing effort displacement from development of  is critical to the sustainability of the Atlantic surfclam fishing industry,” said co-author Daphne Munroe, an associate professor in the Department of Marine and Coastal Sciences in the School of Environmental and Biological Sciences.

“Tools that can predict and manage these complex and interconnected challenges are essential for developing and evaluating strategies that allow for multiple users of the offshore environment.”

Science Center for Marine Fisheries Approves $126,000 in New Research for 2022

January 3, 2022 — The following was released by the Science Center for Marine Fisheries:

The Science Center for Marine Fisheries (SCEMFIS) has funded $126,000 in new marine science research for 2022. The funds, approved by the members of the Center’s Industry Advisory Board at its annual fall meeting, will support new, much-needed research on prominent fisheries such as thread herring, ocean quahogs, squid, and surfclams.

Part of the National Science Foundation’s Industry-University Cooperative Research Centers program, SCEMFIS connects marine scientists with members of the fishing industry to identify scientific priorities for better understanding commercially important fish species, and directs industry funding to projects that study them. Since its founding, SCEMFIS has promoted research that has increased our understanding of these species, and improved their management.

The following research projects were approved by SCEMFIS for 2022:

  • Biostatistical and fishery-dependent sampling of Atlantic thread herring and Atlantic chub mackerel in the mid-Atlantic region – As a result of climate change and the subsequent migration of fish stocks, a fishery for Atlantic thread herring is developing in the Mid-Atlantic. As part of that development, fisheries managers need better biological data on the species in order to manage it sustainably. This project, led by Dr. Robert Leaf (University of Southern Mississippi), will conduct a sampling survey of thread herring to collect data on the fish being harvested by the fishery, including factors such as age, length, and weight. ($69,336 in funding)
  • Ocean quahog population dynamics: project completion – SCEMFIS researchers have worked extensively at expanding our understanding of ocean quahog, especially work in charting the age frequencies for quahogs in the Northwest Atlantic, as well as measuring the uncertainty that comes with estimating the age-at-length of quahogs. This project, led by Dr. Eric Powell (University of Southern Mississippi), and Dr. Roger Mann (Virginia Institute of Marine Science), will complete the Center’s ongoing work on ocean quahog, finishing and publishing current unpublished research on quahog age frequencies. ($41,210 in funding)
  • Genetic and age structure of Southern surfclams – The surfclam fishery has recently resumed fishing in the waters off the coast of Virginia in a region where high bottom water temperatures have led to the deaths of most Atlantic surfclams during much of the 2010s. Increased survival recently may be due to recruitment of the Southern surfclam. To better understand how and why surfclams have returned to this area, this project, led Dr. Daphne Munroe (Rutgers University), will conduct genetic testing on a sample of clams from the area. The tests will help determine their relationship with the rest of the coastwide Atlantic surfclam stock. ($10,795 in funding)
  • Squid age estimation using CAT Scan technology – A recurring challenge in managing squid is the lack of demographic data available to estimate the ages of the squid in the population. This project, led by Dr. Roger Mann, (Virginia Institute of Marine Science), will evaluate the use of CAT scan technology as a tool to age squid. The scans will be used to measure the size of squid statoliths, which are the hard structures in squid heads that grow over time, and attempt to age the squid based on these measurements. ($5,000 in funding).

Clam industry growing as climate change warms New England’s waters

December 20, 2021 — Maine’s clam industry is growing as climate change warms the Gulf of Maine.

The Bangor Daily News reports northern quahogs are among the state’s fisheries that have seen increased harvest volumes and values over the past decade.

The average price of what are also known as hard clams has gone from 40 cents per pound in the 1990s to around $1.50 per pound in recent years, the newspaper reports.

Annual harvest totals have also increased since the early 2000s, reaching a record of more than two million pounds in 2019, according to the paper. The annual harvest value is around $2.6 million, up from just over $10,000 as recently as 2004.

Energy Department announces $10.8M in funding to study impact of offshore wind on East Coast fisheries

October 15, 2021 — The Department of Energy has announced $10.8 million in funding to research the impact of offshore wind on East Coast fisheries and ocean ecosystems. The move is part of President Joe Biden’s plan to tackle climate change by making a big push for renewable energy. But the commercial fishing industry says plans to use hundreds of thousands of acres of ocean to develop wind power will impact the catch.

Clammers and scallop fishermen say they won’t be able to maneuver through the turbines, which would be spaced 1 nautical mile apart. They fear a shrinking patch of fishable ocean will lead to the collapse of the industry.

Some worry about the impact of construction on marine mammals, especially the endangered North Atlantic right whale, which currently has an estimated population of less than 400.

“Harnessing the incredible potential that exists within offshore wind energy is an essential piece of reaching a net-zero carbon future,” Energy Secretary Jennifer M. Granholm said in a statement. “In order for Americans living in coastal areas to see the benefits of offshore wind, we must ensure that it’s done with care for the surrounding ecosystem by coexisting with fisheries and marine life —and that’s exactly what this investment will do.”
