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.
The Fisheries Monitoring and Analysis Division’s North Pacific Observer Program collects, maintains, and distributes data for scientific, management, and regulatory compliance purposes in the Gulf of Alaska and the Bering Sea/Aleutian Islands.
NOAA Fisheries' Alaska Fisheries Science Center Groundfish Assessment Program is conducting the Aleutian Islands bottom trawl survey. So far, the near real-time ocean bottom temperatures included in this PDF were collected from June 3 to August 4, 2026.
NOAA Fisheries' Alaska Fisheries Science Center Groundfish Assessment Program is conducting the eastern Bering Sea bottom trawl survey. So far, the near real-time ocean bottom temperatures included in this PDF were collected from June 1 to August 4, 2026.
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 was completed on July 30, 2025.
The Midwater Assessment and Conservation Engineering Program supports fisheries management through world-class applied science, technology, gear, and data-driven research.
This assessment summarizes and synthesizes climate, biological, and fishing effects on the shelf and slope regions of the Gulf of Alaska (GOA), from an ecosystem perspective, and to provides an assessment of the possible future.
This assessment summarizes and synthesizes historical climate and fishing effects on the shelf and slope regions of the Aleutian Islands (AI) from an ecosystem perspective, and provides an assessment of the possible future.
