Seabirds fly above sediment-laden freshwater discharged from British Columbia's Fraser River into the Salish Sea. Fresh water, which is less dense than salt water, spreads in a shallow (approximately 1 m deep) plume at the sea surface. Sediment carried in this plume then precipitates from the surface, accumulating on the Fraser River Delta below. In Spring, as snow melts in the mountains, the fresh water flow increases significantly and great quantities of sediment are deposited.
