Long-term changes in sediment

We monitor Puget Sound seafloor habitat, sediment, and invertebrate communities to understand the health of this important marine water estuary.

Seafloor research, reports, and findings

Scientists in life jackets and hard hats collect sediment samples from a boat with a stainless steel scoop, a Van Veen grab sampler.

Scientists collect sediment samples.

Our team of scientists is studying the habitat and sediment found on the seafloor of Puget Sound, and the communities of invertebrate animals that live there, in an effort to understand changes that are occurring over time.
