While not exactly a chicken-or-egg debate, when it comes to regulating a deadly tire chemical, Washington state lawmakers are being called upon to decide what comes first in the effort to save salmon. In public hearings this week, speakers were clearly divided in their views on companion bills in the House and Senate to ban […]

Washington lawmakers to decide whether to ban a tire chemical shown to be toxic to salmon
A new bill introduced to the Washington Legislature, now in session, would require tire manufacturers to reformulate the rubber in their tires to remove a chemical responsible for killing large numbers of coho salmon and other fish. If approved, the legislation would give tire manufacturers nine years to find a suitable replacement for the compound […]

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 […]

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 […]

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 […]

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 […]

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 […]

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 […]

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 […]

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 […]
