We are working to better understand Alaska ocean ecosystems and to gather information to ensure healthy fish, crab, and marine mammal populations. We use innovative technologies to both monitor and study marine life and habitat.
Water temperature affects many species' spawning times, access to food, and range. Collecting temperature data provides insight into the state of the ecosystem. Here, we shared bottom temperature data from this survey.
In 2025, NOAA Fisheries’ Alaska Fisheries Science Center conducted two surveys within U.S. territorial waters of the Bering Sea: the southeastern Bering Sea shelf bottom trawl survey and the northern Bering Sea bottom trawl survey.
Water temperature affects many species' spawning times, access to food, growth rates, and overall range. Collecting temperature data helps better understand species’ habitats and the larger ecosystem. This survey wrapped up on August 22, 2025.
