At NOAA Fisheries, we are working to better understand Alaska ocean ecosystems and to gather needed information to ensure healthy fish, crab, and marine mammal populations. We do this by using varied and innovative technologies to both monitor and study marine life and habitat. Here's a look at some of the tools, techniques and technologies we use.
We conduct research and monitoring surveys to better understand the physical, biological, economic, and social components of marine ecosystems found in the Northwest Atlantic Ocean from the Canadian Scotian Shelf to Cape Hatteras, North Carolina.
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.
Our Gulf of Maine Bottom Longline Survey collects data on species that prefer rocky habitats—a habitat not efficiently sampled with trawl gear used in bottom trawl surveys
The most comprehensive, ongoing program exploring marine resources and oceanographic conditions in the Northwest Atlantic. Our analyses inform local and international fisheries management, protected species research, and climate science.
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.
