Knowra Puget Sound Puget Sound Puget Sound is a network of marine waterways in Washington State, connected to the Pacific Ocean through the Strait of Juan de Fuca. Its deep, branching inlets include bays, passages, and basins.
Salish Sea : The inland sea spanning waters of Washington State and British Columbia, including Puget Sound, the Strait of Georgia, and the Strait of Juan de Fuca. Puget Sound is the southernmost major region of this larger inland sea.
Tides of Puget Sound : The regular rise and fall of sea level in Puget Sound, driven mainly by ocean tides entering through the Strait of Juan de Fuca. Tidal exchange moves water through the sound’s connected inlets and basins.
Puget Lobe : The lobe of the Cordilleran Ice Sheet that advanced south through the Puget Lowland during the last glaciation. Its advance and retreat excavated and reshaped the lowland containing Puget Sound.
Port of Seattle : A major Washington port operating container terminals, cruise facilities, and other maritime infrastructure in Seattle. Its harbor is one of the sound’s principal centers for shipping and maritime trade.
Urbanization in Puget Sound : The growth of cities and infrastructure around Puget Sound’s shorelines and watersheds. Urban development has altered habitat and increased pressure on the sound’s ecosystems.
Strait of Juan de Fuca : A strait between Washington State and Vancouver Island that connects the Pacific Ocean to the Salish Sea. This strait forms Puget Sound’s principal ocean connection.
Puget Sound circulation : The movement and mixing of water among Puget Sound’s basins, shaped by tides, winds, and freshwater inflows. Circulation determines how quickly water and dissolved materials move between basins.
Puget Lowland : A low-lying region between the Cascade Range and Olympic Mountains in Washington State and British Columbia. Puget Sound occupies the northern part of this geologic lowland.
Port of Tacoma : A major seaport in Tacoma, Washington, serving container shipping and other cargo operations. Its facilities anchor a major commercial harbor in southern Puget Sound.
Stormwater pollution : Contamination carried into waterways by rainwater runoff from streets, roofs, and other developed surfaces. Runoff from developed watersheds carries pollutants into Puget Sound and its tributaries.
