Questions about where salmon go and how they survive when traveling far out into the Pacific Ocean have puzzled scientists for 200 years. But a new vision for piecing together this intricate puzzle has begun to emerge, thanks to sophisticated research tools deployed during an international expedition this past winter. Last week, scientists got together […]

Add-on structure will begin to address steelhead crisis at the Hood Canal Bridge
The Hood Canal Bridge, which connects the Kitsap and Olympic peninsulas, has proven to be a dangerous impediment to juvenile steelhead trout. As many as half of the young migratory steelhead in Hood Canal may get picked off by seals, birds and other predators as the fish try to pass under the floating highway, according […]

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 […]
