" alt="Looking back on a year of Puget Sound surprises: rare birds, gray whales, water"> 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. Cold […]

" alt="Experts expect the recent arrival of chum salmon to bring orcas back to Puget Sound"> UPDATE: Monday, Nov. 3 Whales return to Central Puget Sound without youngest calf All three pods of southern resident killer whales traveled into Central Puget Sound Sunday, making it as far south as the southern end of Vashon Island, if not farther. The past few days, various whales have been spotted in the San Juan […]

" alt="Annual orca count grows by one, as the Puget Sound whales stay on the hunt for food"> Although an official census report is not due until October, it appears that the population of our southern resident killer whales has increased by one over the past year. That slight increase is the net result of four births and three deaths, according to the Center for Whale Research, which is responsible for the annual […]

" alt="A photographic tour of the entire Puget Sound shoreline by watercraft and aircraft"> Kayaker-scientist Brian Footen is back on the waters of Puget Sound this summer, paddling through inlets and circling islands on a 2,700-mile journey to photograph the shoreline and document natural and human-caused changes to the habitat. This state-funded project is Brian’s second photographic trip along the sinuous shoreline throughout the entirety of the Sound, from […]

" alt="Low oxygen challenge, part 4: Many actions may be needed to improve Puget Sound waters"> A grand plan to reduce human sources of nitrogen in Puget Sound started coming into focus in 2019 when the issue of regulations reached a decisive point. After years of study and advances in computer modeling, experts at the Washington Department of Ecology were beginning to see what it would take to reduce human sources […]

" alt="Low oxygen challenge, part 3: Computer models spell out the extent of the water-quality problem"> After more than eight years of study amid ongoing discussions, the Washington Department of Ecology has made public a far-reaching plan for reducing human sources of nitrogen that contribute to the destructive low-oxygen conditions in Puget Sound. The plan, called the Puget Sound Nutrient Reduction Plan, calls for reductions in nitrogen from sewage-treatment plants, agricultural […]

" alt="Low oxygen challenge, part 2: Water-cleanup plans and the search for ‘reasonable’ actions"> On a clear autumn day, the blue waters of Budd Inlet reflect the distant snow-capped Olympic Mountains. From the water’s surface, nobody can tell if low-oxygen conditions might be lurking below, as they often do, creating a stressful or even deadly environment for sea life. The fact that beauty can disguise the harsh reality of […]

" alt="Low oxygen challenge, part 1: The debate over oxygen in Puget Sound"> In Puget Sound, low oxygen levels are a proven threat to marine creatures, from fish to shellfish and even tiny organisms. This threat has long been recognized by scientists — particularly within slow-flushing bays and inlets where low levels of dissolved oxygen can impair sea life and occasionally create deadly conditions in late summer and […]

" alt="New law requires sewage spills to be revealed to the public through a new statewide website"> Mindy Roberts of Washington Conservation Action said someone asked her a few years ago about the frequent sewage spills occurring in Tacoma’s Thea Foss Waterway. “My answer was, ‘What sewage spills?’” Mindy recalled, quickly realizing that if she didn’t know about sewage spills in her own city, then hardly anybody else was likely to know […]

" alt="Eating fish: Court order may end the battle over toxic standards in Washington state waters"> It appears that a decade-long battle to establish allowable levels of toxic chemicals in Washington state’s waterways may finally be over. Strict toxic standards, first imposed on the state in 2016 by the Environmental Protection Agency, seem to have prevailed. Primary chemicals of concern in the long battle over human health criteria include polychlorinated biphenyls, […]
