From Krill to Elephant Seals, Sentinel Species Detect Hidden Ocean Shifts that Forecast Change

3/18/2025 - By fisheries.noaa.gov. New research identifies species that signal changes in ocean ecosystems. Northern elephant seals weigh in at several thousand pounds and quickly put on more weight when catching squid, fish, and other prey. They feed off the California coast in the so-called “twilight zone” of the ocean (200 to… SEE MORE

Where Do Atlantic Salmon Go to Beat the Heat?

11/25/2024 - By fisheries.noaa.gov. As a key river habitat warms, researchers race to protect cold water patches critical to salmon survival. Researchers have successfully used cameras operated from a helicopter to map surface water temperatures in Maine’s Narraguagus River. This is an important step toward habitat conservation for endangered Atlantic salmon and… SEE MORE
