Marine water & sediment monitoring
We conduct long-term monitoring of water and sediment to identify ecosystem changes in Puget Sound, Grays Harbor, and Willapa Bay using a variety of instruments and sampling gear deployed from seaplanes, boats, and passenger ferries.
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.
To support healthy ecosystems in Washington, we collect high-quality environmental data about the water column and sediments. A long-term data record allows us to detect both long-term patterns and short-term changes to share with scientists and to inform policymakers. You can download water-column profile data. If you need discrete data or help finding what data you need, contact Julianne Ruffner.
