Salish Sea

Salish Sea. The Salish Sea is a marginal sea of the Pacific Ocean located in the Pacific Northwest, encompassing a complex network of coastal waterways between the southwestern corner of British Columbia and the northwestern corner of Washington. This inland sea includes the Strait of Georgia, the Strait of Juan de Fuca, Puget Sound, and all their connecting channels and basins. The name recognizes the Coast Salish peoples, whose cultures and histories are deeply intertwined with these waters, and was officially adopted in 2010 following a proposal by marine biologist Bert Webber.

Geography and boundaries

The Salish Sea is defined by the interconnected basins of the Strait of Georgia, the Strait of Juan de Fuca, and Puget Sound, bounded to the west by the Pacific Ocean at the entrance to the Strait of Juan de Fuca. Its northern boundary extends to the Discovery Islands near Campbell River, while its southern reach includes the inlets of South Puget Sound near Olympia. Major freshwater inputs come from the Fraser River, the largest river entering the sea, and the Skagit River, along with many others like the Nisqually River and the Squamish River. The international border between Canada and the United States runs through Haro Strait and the middle of the Strait of Juan de Fuca.

History and naming

For millennia, the region has been home to numerous Coast Salish nations, including the Stó:lō, Lummi, Suquamish, and Swinomish, among many others. European exploration began with Spanish mariners like Francisco de Eliza and Manuel Quimper, and British captains including George Vancouver and James Cook. The sea's contemporary name was championed by American marine geographer Bert Webber in the 1980s to provide a single ecological and cultural identity for the transboundary waters. After years of advocacy, the name was officially recognized in 2009 by the Washington State Board on Geographic Names and in 2010 by the United States Board on Geographic Names and the Geographical Names Board of Canada.

Ecology and environment

The Salish Sea is a highly productive ecosystem supporting a rich diversity of marine life, including iconic species like Southern Resident killer whales, Pacific salmon, and humpback whales. Its extensive estuaries and eelgrass beds provide critical habitat for juvenile fish and migratory birds along the Pacific Flyway. The system faces significant environmental pressures from urban runoff, pollution from cities like Seattle and Vancouver, and the impacts of climate change, which contribute to challenges such as ocean acidification and declining chinook salmon populations. Conservation efforts are coordinated by entities like the Puget Sound Partnership and the Georgia Strait Alliance.

Human use and significance

The sea is a vital economic and cultural corridor, supporting major ports such as the Port of Vancouver and the Port of Seattle, which are key hubs for international trade and commercial fishing. It is also central to the cultural practices and sustenance of Coast Salish peoples, who continue to exercise their treaty fishing rights. The region is a premier destination for recreation and tourism, known for whale watching, kayaking, and ferry travel operated by Washington State Ferries and BC Ferries. Numerous academic institutions, including the University of Washington and the University of Victoria, conduct extensive marine research in these waters.

Major waterways and features

Key components of the Salish Sea include the deep, glacier-carved basin of the Strait of Georgia, the tidal gateway of the Strait of Juan de Fuca, and the intricate fjord system of Puget Sound. Significant adjoining waterways are the San Juan Islands archipelago, the Gulf Islands, Rosario Strait, Admiralty Inlet, and Hood Canal. Major cities and settlements on its shores include Vancouver, Victoria, Seattle, Bellingham, Nanaimo, and Everett. Notable natural features include the tidal rapids of Skookumchuck Narrows and the expansive delta of the Fraser River.
