October 7 roundtable about THORR, which maps river temperatures from space

The Salish Sea Science Roundtable online speaker series continues on Tuesday, October 7 from 12:30 – 1:30 pm. The University of Washington’s Thermal History of Regulated Rivers (THORR) tool transforms NASA’s Landsat satellite imagery into current and historical river temperature insights. Learn how advanced data-driven techniques enable accessible mapping of water temperatures across remote streams—vital for […]

August 15: Temperature-dependent oxygen supply and demand — a pilot on marine life vulnerability in Puget Sound

Friday, August 15 from 11 am – 1 pm  We’re excited to continue the Science of Puget Sound Water Quality workshop series, which explores emerging science and insights to help protect water quality in Puget Sound. Not only does warmer water hold less oxygen, but it simultaneously increases how much oxygen marine species need, so […]

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 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 […]
