Regulatory efforts to confront low-oxygen problems in Puget Sound have turned toward sewage treatment plants, as the Washington Department of Ecology proceeds to reissue operational permits, some ahead of the normal five-year schedule. Excess nitrogen has been found to contribute to low-oxygen problems in Puget Sound, and computer models have identified locations where reducing nitrogen […]

Testimony in legislative committees focuses on when a toxic tire chemical should be banned
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.

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 […]

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 […]
