"> PSI collaborator receives NSF grant to study coho deaths
PSI collaborator Ed Kolodziej has received a $330,000 National Science Foundation grant to expand his research on toxic pollutants in Puget Sound. Kolodziej’s project will identify chemicals in stormwater that are killing coho salmon and endangering some spawning runs. The project includes a collaboration with citizen scientists who will alert project members to salmon die-offs […]
