Salish Sea Science Roundtable begins in October

While there are often opportunities to go deep in our respective fields, breakthroughs can come from unexpected connections and interdisciplinary discussions. The Salish Sea Science Roundtable is a virtual monthly seminar inspired by just that. UW Puget Sound Institute is co-convening the roundtable with several organizations, including Fisheries and Oceans Canada. Each month we’ll connect to […]

Symposium grapples with long-lasting PCBs

Researchers at the Puget Sound Institute hosted a two-day symposium last month to share information about the science and management of PCBs in the environment. The online workshops, held January 24th and 25th, were organized by PSI researchers Andy James, Joel Baker, and Marielle Larson, in coordination with colleagues Will Hobbs (Washington State Department of […]

Low-oxygen problems to be scrutinized in talks about research, modeling efforts

By Christopher Dunagan For decades, researchers have been advancing their understanding of what causes the harmful and sometimes deadly low-oxygen problems afflicting some areas of Puget Sound. Computer models have been developed to replicate conditions and point the way to possible solutions. Experts generally agree that excess nitrogen flowing into Puget Sound contributes to the […]
