Protection Island, a National Wildlife Refuge in the Strait of Juan de Fuca, provides important habitat for seabirds and marine mammals.

The Puget Sound Institute is a cooperative agreement between the University of Washington, the U.S. Environmental Protection Agency, and the Puget Sound Partnership, seeking to catalyze rigorous, transparent analysis, synthesis, discussion and dissemination of science in support of the restoration and protection of the Puget Sound ecosystem.

A November 2013 paper in the journal Conservation Letters examines the importance of cultural values to ecosystem-based management of coastal environments. Extended abstract by Melissa Poe of NOAA Fisheries and Washington Sea Grant, with Phil Levin and Karma Norman.

The following article describes how both adult and juvenile steelhead trout use estuaries in Puget Sound and includes text from two previously published overviews on the subject by University of Washington biologist Thomas P. Quinn.

Canadian and U.S. governments differ on special status for bocaccio in the Salish Sea. 

Scientists argue that herring managers should take a tip from stock market investors and diversify the population’s “portfolio.” 

Researchers are looking at the forces of discrimination that worsen the environmental health risks for some communities.

The Salish Sea Marine Survival Project has mobilized dozens of organizations in the U.S. and Canada to find an answer to one of the region's greatest mysteries. What is killing so many young salmon before they can return home to spawn? A series of talks at the 2016 Salish Sea Ecosystem Conference brought together some of the latest research. 

The Quinault Indian Nation includes the Quinault and Queets tribes, as well as descendants of five other coastal tribes. The tribe's headquartes are located in Taholah, Washington. Quinault Area of Concern: The Quinault Nation focuses their restoration efforts in the Chehalis River basin, one of the largest in Washington State. Over 81% of the land is forested, and most is privately ...

In many parts of Puget Sound, hypoxic waters are thought to be at least in part due to overgrowth of microscopic algae, which is triggered by excess nitrogen. That means it’s important to understand the dynamics of primary productivity – the rate at which those microscopic algae, known as phytoplankton, produce organic matter through photosynthesis and in this way provide the base of the food web. Researchers are investigating different types of phytoplankton and rates of primary productivity throughout the Salish Sea, and seeking to understand how primary productivity is likely to change as climate change alters patterns of coastal upwelling and freshwater flow into the Sound.
