Science & Data

NOAA Fisheries' science-based conservation and management of sustainable fisheries, marine mammals, endangered species, and their habitats have become global models for marine stewardship and sustainability.

Our research surveys provide data critical to the stewardship of our nation's ocean resources and their habitat. For 150 years, our scientists and partners have collected survey data to understand current and changing ocean conditions and monitor marine life. The insights we gain are the heart of our science-based conservation and management. 

Effective science-based conservation and management are essential to ensuring sustainable domestic seafood production, maintaining and enhancing fishing opportunities, recovering protected species, and safeguarding ecosystem health.

Capelin: a “Sea Canary” for Marine Ecosystem Change in Response to Heatwaves

Capelin are a major forage fish species in high-latitude marine ecosystems. Recent heatwaves in Alaska led to a dramatic decline in capelin abundance, which can have major impacts on predators, including marine mammals, seabirds, and fish.

Those Who Go to Sea

Field Fresh Blog: Science in Motion

What draws people to the ocean and fishing? Field scientist Hannah Ciarametaro asked the captain and crew of the F/V Miss Trish II that very question. Their stories touch on duty, pride, peace, money, and the toll it takes on them and their families.

Groundfish Gut Check: Partnering with the Fishing Industry to Update Groundfish Data

Field Fresh Blog: Science in Motion

Field scientist Hannah Ciarametaro works with the Northeast’s fishermen to update groundfish conversion factors for better data. She encounters some blood and guts along the way.

Two people sit on the left and right sides of a bright yellow undersea glider while on a vessel in the ocean. They are wearing life jackets, sunglasses, and sun-protective clothing. The deep blue ocean is visible behind them. Dr. Selene Fregosi (right) and Jeremy Taylor, Pacific Islands Fisheries Science Center, supported NOAA Fisheries’ undersea glider challenge in Hawaiʻi in early 2026. The challenge assessed glider performance and capabilities in field conditions off Oʻahu. Credit: NOAA Fisheries/Calla Lloyd-Lim
