Coastally-trapped Kelvin waves, a signature of El Niño, traveled north along the West Coast during the 1997/1998 El Niño, as shown in a map of sea surface height anomalies. Darker reds show sea levels higher than normal, while darker blues show heights below normal. Scientists are now watching for similar waves to move up the West Coast this fall.

Ocean Indicators We’re Tracking for El Niño’s Arrival on the West Coast

9/5/2026 - By fisheries.noaa.gov, fisheries.noaa.gov. Has El Niño reached the West Coast? You might think it has. After all, the ocean off Southern and Central California is unusually warm. But that is from a recent marine heatwave predates the current El Niño. Much of the Pacific Coast is experiencing relatively normal conditions while still… SEE MORE

Beyond Ocean Mapping: Using Uncrewed Vehicles to Advance Ocean Research

8/26/2026 - By fisheries.noaa.gov, fisheries.noaa.gov. It’s January off of Nantucket Shoals. An uncrewed surface vehicle begins a series of carefully planned transects through Southern New England, collecting data day and night. There are no scientists onboard, but the 30-foot vessel is constantly measuring ocean currents, water temperature, salinity, weather and other ocean… SEE MORE

Technology Week: Launching into the Future with Advanced Technologies

8/21/2026 - By fisheries.noaa.gov, fisheries.noaa.gov. NOAA scientists rely on cutting-edge technology to collect and analyze the data needed to manage our ocean resources and habitats. Because some ocean creatures live in remote areas and have complex life cycles, better understanding them requires unique tools. By leveraging advanced technologies, we gather critical data to… SEE MORE
A researcher in a U.S. Coast Guard helicopter first spotted the entangled humpback anchored to the bottom about 20 miles off the Oregon Coast. The whale’s white pectoral flipper extends underwater to the lower left, while white baleen outlines its open lower jaw at bottom right. The entanglement left the whale’s mouth stretched permanently open, making it unable to feed. Photo collected in partnership with Oregon Coast Aquarium, Oregon State University Marine Mammal Institute and Cascadia Research Collective.

Fishing Vessel Joins Trained Team to Free Injured Humpback Whale 20 Miles off Oregon Coast

8/16/2026 - By fisheries.noaa.gov, fisheries.noaa.gov. An Oregon team joined by experts from Washington and a local fisherman freed a severely entangled humpback whale about 20 miles off the Oregon Coast on July 26. While the team removed all of the gear from the whale, the entanglement left the young whale’s jaw permanently… SEE MORE

NOAA Scientists Discover Repeat Spawning in Pacific Capelin

8/12/2026 - By fisheries.noaa.gov, fisheries.noaa.gov. For certain fish species, like Pacific salmon, reproduction is a once-in-a-lifetime event, known as semelparity. Many other fish are iteroparous—meaning they can spawn repeatedly throughout their lives. New research by NOAA’s Alaska Fisheries Science Center reveals the first evidence that Pacific capelin can be repeat spawners. Over the past decade,… SEE MORE

NOAA Fisheries Enforcement Officers Deploy for High Seas Patrols Combatting Illegal, Unreported, and Unregulated Fishing

8/9/2026 - By fisheries.noaa.gov, fisheries.noaa.gov. Enforcement officers from NOAA Fisheries’ Office of Law Enforcement have successfully wrapped up deployments for Operation North Pacific Guard, an annual international mission targeting illegal, unreported, and unregulated (IUU) fishing on the high seas. The officers, who used their specialized experience to support the operation, patrolled over 8,000 nautical miles aboard… SEE MORE
