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 …

PSI launches Salish Sea Modeling Center

The Puget Sound Institute is launching a new program that will use supercomputers to advance ecosystem recovery of the Salish Sea. The Salish Sea Modeling Center will allow scientists from around the region to access sophisticated computer models to predict changes in the ecosystem. Work at the center will tackle vexing environmental problems such as …

Does Puget Sound need a diet?

As the region’s population grows, scientists say we can expect to see increasing amounts of nitrogen and other elements flowing into Puget Sound. Known as “nutrients” these elements are naturally occurring and even necessary for life, but officials worry that nutrients from wastewater and other human sources are tipping the balance. That could mean big …
