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 […]

Series of workshops will advance understanding of nutrients in Puget Sound

Our region is navigating complex and challenging decisions on how best to manage nitrogen, dissolved oxygen, and the potential impacts of eutrophication on the key habitats and species of the Salish Sea. Over the next year, the Puget Sound Institute is sponsoring a series of scientific workshops to help address technical uncertainties and to advance modeling […]
