Marine water & sediment monitoring
We monitor and assess marine water and sediment to identify ecosystem changes in Puget Sound and coastal bays using a variety of instruments, sensors, and sampling gear deployed from boats and passenger ferries. We study understand natural and human influences on Puget Sound objectively and quantitatively. Our data record allows us to detect both long-term patterns and short-term changes to share with scientists and policymakers
Estuaries such as Puget Sound have large natural variations in depth, water circulation, influences from the ocean, and seasonal conditions. All of these variables influence the quality of the water column and the sediment found at the bottom of the sea and the organisms living there.
