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.

NOAA's GOES West satellite captured this image of three tropical cyclones — Hurricanes Fausto and Genevieve and Typhoon Dolphin — swirling simultaneously in the Pacific Ocean. The image was taken on Tuesday, July 27, at 3:30 PM PDT/ 22:30 UTC. None of the three tropical cyclones made landfall in the United States. Fausto contributed to high surf conditions in Hawaii, and Genevieve also brought high surf to southern California. Typhoon Dolphin continued its track west toward Asia.

8/13/2026

By noaa.gov, noaa.gov. It may be surprising, but two of the hurricanes that swirled in the Pacific last week began their journeys thousands of miles away off the western coast of Africa. Both Hurricanes Fausto and Genevieve developed from tropical waves, which are areas of disturbed weather that rolled off… 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
