Increasing concerns surround PFAS in products from wastewater treatment plants. How great a risk do they pose, and are there feasible approaches to removing them? We continue our occasional series on water quality and wastewater management in Puget Sound. Funding for the series is provided in part by King County.
The year 2025 has been fairly mystifying to experts who make their living studying natural systems in the Puget Sound region.
Unusual observations this year include record-low dissolved oxygen levels, unexpected gray whale visitations, and the sudden arrival of an astounding number of short-tailed shearwaters — a seabird almost never seen in Puget Sound.
Marbled murrelets are a rare sight in Puget Sound. The threatened birds have declined severely in California, Oregon, and Washington, and biologists are intrigued by their summer presence in Commencement Bay.
Crab Team members maintain a massive surveillance program to track the population’s advance, while researchers probe the inner workings of the invasive species.
In August 2024, the U.S. Fish and Wildlife Service and the Jamestown S’Klallam Tribe signed an agreement to become co-managers of two national wildlife refuges in the Puget Sound region. It was the first agreement of its kind in the state, and since that time, the tribe has been leading site operations at Dungeness Spit and Protection Island, greeting visitors, fixing roads, and hosting scientists. We spoke with refuge manager Fawn Wagner to get her insights into what it means for both wildlife and the tribe's strong historical and cultural relationship with the region.
Gulls are perhaps our most familiar seabird. Pick a seashore or even an occasional landfill, and you are likely to see at least a few. But casual sightings don't always paint a true picture of population health. Recently, scientists took to the field to see how glaucous-winged gulls are faring in the Salish Sea. The gulls were ready for them.
