The Salish Sea is an inland sea along the Pacific Coast of North America.
The U.S. Geological Survey (USGS) defines the Salish Sea as:
"5,500 square miles; extends from the mouth of the Strait of Juan de Fuca
eastward and northward to include Puget Sound and Georgia Strait, and
their associated bays, coves, and inlets."
The Salish Sea is home to several of North America's most famous port cities including Vancouver, Seattle, Tacoma, Bellingham, Port Angeles and Victoria.
The first known use of the term Salish Sea was in 1988, when marine biologist Bert Webber from Bellingham, Washington, created the name for the combined waters in the region. The term was officially recognized by British Columbia in 2010.
