Puget Sound is a deep inlet of the Pacific Ocean in Washington, extending south from the Strait of Juan de Fuca through Admiralty Inlet. It was explored and named by Captain George Vancouver for his aide, Peter Puget, in 1792. The ninth Puget Sound Update, from the Puget Sound Action Team reports that: "the Puget Sound has biological resources which include all of the living organisms which inhabit the marine waters and shorelines. These biological resources are plankton, invertebrates, fish, birds, mammals, and aquatic vegetation, including species that are either residential or migratory."
