Pacific sand lance captured in a beach seine. Sand lance are a forage fish that underpin Puget Sound food webs and are intimately connected to Puget Sound beaches. The fish spend a portion of their time buried in the sand and eggs are laid on the upper beach, making healthy beaches critical to the success of this species.

USGS scientist Collin Smith, aboard USGS research vessel Dogfish, sets out a sampling net—called a lampara net—to capture nearshore fishes in a subtidal eelgrass bed in Eagle Harbor, Bainbridge Island, Washington.

The turbid waters of the Elwha River and the coastal waters of the Strait of Juan de Fuca mix directly offshore of the river mouth, forming a large coastal plume.  This plume is easily identified by the cloudiness of the water (or "turbidity") resulting from sediment discharged by the river.  Two large dams on the Elwha River are being incrementally r

Bird's-eye view map of a section of the seafloor off southern California, made with depth data. The map shows a channel wall that has been cut by the San Diego Trough fault and moved about 20 meters. This feature is about 1,000 meters below sea level.
