NOAA model designed to help assess coastal flood risks

Janauary 13, 2025 — Coastal communities along the Atlantic, Caribbean and Gulf coasts can now better assess changing flood risks using a newly released model created by the National Ocean Service.

The service, which falls under the National Oceanic and Atmospheric Administration, on Monday launched Coastal Ocean Reanalysis, or CORA, a dataset that includes more than four decades of modeled, historical water level and wave information roughly every quarter mile along the U.S. coastline.

CORA closes what have been in some areas of the coast huge gaps in water level data collection that left some coastal communities without such information. That’s because historical data was until today available at NOAA’s tide gauge locations, which can be hundreds of miles apart along some areas of the coast.

“Historical coastal water level information is necessary to assess changing flood risks to communities and to predict the likelihood of flooding,” National Ocean Service Director Nicole LeBoeuf said in a release. “This new dataset will improve NOAA’s current flood-risk assessment tools and help scientists develop new coastal flood products and services for the nation.”

Alaska cities reach agreement on Bering Sea snow crab harvest

January 9, 2025 — The cities of Unalaska and St. Paul in the U.S. state of Alaska have reached an agreement to share revenue collected from the processing of 1.6 million pounds of Bering Sea snow crab.

After two years of closures, NOAA Fisheries announced in October 2024 that it would be opening up the Bering Sea crab fishery for a limited harvest with a 4.7 million pound total allowable catch (TAC). Around 1.6 million pounds of that TAC was designated for the North Region, which, according to a framework agreed to by harvesters and processors in September 2024, had to be processed in St. Paul.

Building Resource and Community Resilience to Rapidly Changing Oceans

January 8, 2025 — Climate change is driving rapid changes in U.S. marine and Great Lakes ecosystems. The impacts range from devastating marine heatwaves to shifts in the distribution and abundance of commercial and recreational fish stocks. These changes are already impacting these important resources and the people, businesses, and coastal communities that depend on them.

NOAA Fisheries is committed to helping resource managers, businesses and coastal communities build resilience and adapt to changing ocean environments. To be successful, we need up-to-date information on what’s coming, what’s at risk, and how best to prepare and respond.

NOAA’s Climate, Ecosystems, and Fisheries Initiative (CEFI) is designed to address these needs and transform how we approach and respond to changing ocean and Great Lakes conditions. CEFI is a cross-NOAA effort to build a nationwide decision support system to help reduce impacts and increase resilience. For the first time, NOAA will regularly provide robust forecasts of future ocean ecosystem conditions, information on what’s at risk, and advice on best strategies for resilience and adaptation.

Genetic Diversity in Alaska Red King Crab May Provide Resilience to Climate Change

January 3, 2024 — Maintaining genetic diversity within and among populations is vital to ensure species are resilient to challenging conditions. Without it, a single disease or set of conditions—such as a prolonged change in ocean acidification—could drive a species to extinction. Fortunately, new research has revealed more genetic diversity across Alaska’s red king crab populations than originally documented. This suggests that the species will be more resilient in the face of changing conditions like ocean warming. However, any efforts to enhance red king crab populations need to be careful not to affect this genetic diversity.

King Crab in Alaska

Historically, the red king crab fishery was Alaska’s top shellfish fishery. It’s embedded in the culture of Alaska’s working waterfronts and king crabs have been the centerpiece of holiday feasts around the world. However, the red king crab fishery collapsed in the 1980s. Since 1983, most populations have been depressed statewide and the Gulf of Alaska fishery remains closed.

Wes Larson is co-author of the new research and the genetics program manager at the NOAA Alaska Fisheries Science Center. He reflects, “When it comes to understanding crab biomass declines and how to recover populations, we need to better understand population structure and local adaptation. There are a lot of concerned and invested fishermen, processors, and community members getting more engaged in these issues and it’s propelling new and innovative research.”

To dig into this need, Larson and a team of collaborators embarked on a study to generate whole genome sequencing data on red king crab in different locations across Alaska. The benefit of whole genome sequencing over previous methods is that it’s akin to reading the full story of an organism’s makeup instead of just a chapter or two. This holistic approach offers more robust analysis in order to tease apart similarities and differences between locations. Collaborators on the research included:

  • Cornell University
  • University of Alaska Fairbanks
  • Alaska Department of Fish and Game
  • NOAA’s Alaska Fisheries Science Center

ALASKA: NOAA announces up to $1 million in funding for crucial research projects — here’s why we should be paying attention

December 30, 2024 Alaska is known for its beauty, northern location, fishing industry, and harsh winter weather. Now, the resilient state is set to benefit from up to $1 million to support research geared toward its local communities, as reported by NOAA.

During the first year alone, the remote state will receive about $500,000 of that funding thanks to the Inflation Reduction Act signed by the Biden-Harris administration in 2022.

Alaska may be the country’s largest state by land mass, but it has a sparse population in comparison — one projected to decline by 2% or 15,000 people by 2050, according to Alaska’s Department of Labor and Workforce Development.

Pacific salmon restoration efforts see massive influx of funding from US Congress

December 30, 2024 — As Pacific salmon navigate their way upstream to spawn along the U.S. West Coast, they desperately need patches of cold water to rest and replenish.

Historically, log jams provided many of these fish refuge by diverting the flow of rivers and creating deep, cool pools of water for salmon to recover on their epic journey. Due to human interference, many of those naturally occurring barriers and the adjacent wooded areas that created them are gone, degrading salmon habitats and making passage more difficult for the species.

Fish, crab may shift to further north waters

December 27, 2024 — Regional models being developed by NOAA Fisheries indicate that some fish and crab may shift further north in Alaskan waters than previously predicted due to climate change.

A new report issued by NOAA Fisheries on Dec. 17 says scientists have developed new models that predict more extreme changes in the ecosystem of the eastern Bering Sea by the end of the century, with larger summer northward shifts and changes in areas occupied by important commercial crab and fish species.

Specifically, the majority of models estimate changes in the center of distribution for several commercially important species. They predict that most species’ summer distributions will shift north by between 50 and 200 kilometers by 2080-2089.

Scientists also project large declines in the amount of area occupied by red king crab and snow crab and potentially northern rock sole in summer months, a substantial increase in area occupied by arrowtooth flounder who are a key predator of walleye pollock and declines in probability of occurrence of most species in areas with low pH and oxygen concentration.

New law targets ‘ghost fishing’ by old gear. How discarded traps and nets are harmful

December 26, 2024 — Abandoned fishing gear has posed problems for authorities wishing to clear it from state waters and shorelines for decades, but new legislation is aimed at making that task easier.

An amendment by state Senate Minority Leader Bruce Tarr, R-Gloucester, to an existing statute will speed the process of removing the environmentally harmful debris.

“Left unchecked, abandoned fishing gear poses several threats to our marine environment and ecosystems,” Tarr stated in a press release.

One of the problems it creates, he said, is “ghost fishing.”

According to the NOAA Marine Debris Program, “Ghost fishing occurs when lost or discarded fishing gear that is no longer under a fisherman’s control continues to trap and kill target species like fish and crustaceans, and non-target species like marine mammals, sea turtles, and seabirds. Derelict fishing nets and traps can continue to ghost-fish for years once they are lost under the water’s surface. Storms, ship traffic, and interactions with other types of fishing gear are the primary mechanisms for gear loss, resulting in an estimated 1% to 5% annual rate of gear loss in the Massachusetts lobster fishery. In Cape Cod Bay, derelict lobster traps are estimated to kill 12,500 to 33,000 lobsters per year. By removing derelict fishing gear, ghost fishing can be reduced.”

Aquaculture cited as strong tool for climate resilience

December 26, 2024 — A new aquaculture report released by NOAA Fisheries on Dec. 17 cites aquaculture as increasingly important in the nation’s commitment to food security, climate resilience and protection of threatened and endangered marine and freshwater species.

The updated National Aquaculture Development Plan credits aquaculture as one of the most environmentally sustainable ways to produce healthy food and also cites aquaculture for its important role in fisheries restoration.

Hatchery-reared fish are released into the wild to help boost populations of wild marine species.

According to NOAA Fisheries, aquaculture has helped more than 70 endangered or threatened species – including Pacific salmon, white abalone, and queen conch – and has also helped restore habitats and mitigate impacts of climate change.
