NOAA scientists pinpoint increased juvenile-to-adult mortality connected to recent heatwaves as a major factor in recent Chinook salmon declines on the Yukon River.
How do Pacific cod respond to warming seas, and what does it mean for the future of fisheries? Satellite tagging helps scientists track cod migration in Alaska and understand the implications for stock assessments and sustainable management.
Researchers identify distinctive genetic stocks of Pacific cod in Alaska and use that information to build a cost-effective genetic tool to answer important ecological questions for the species.
Back-to-back record spawning seasons suggest that reconnecting tributaries and restoring salmon habitat is supporting Central California Coast Coho population growth. NOAA has funded more than 100 restoration projects on the Mendocino Coast.
Scientists flew more than 24,000 miles over sea ice to study the abundance and distribution of seals in the Bering, Chukchi, and Beaufort seas. This was the first time the seals’ entire geographic range in U.S. waters was surveyed in one season.
New research on haul-out behavior helps to more accurately estimate the number of ice seals in the Arctic, and improve our efforts to conserve and monitor their populations.
A new study uses spatial models to precisely map how Pacific cod prey on commercially important snow and southern Tanner crabs in the eastern Bering Sea.
