Description South Puget Sound is a complex interconnected system of straits, open reaches, and fjord-like bays. Low near-bottom dissolved oxygen (DO) is observed in some years at the north end of Case Inlet. Sub-tidal flow patterns around Harstine Island can partially explain this variability in DO. This residual flow alternates between an H pattern with circulation splitting around Harstine Island, and a surface clockwise O pattern with flow mostly out through Pickering Passage. We deployed two current meters in Dana and Pickering Passages for several months and conclude that the residual flow pattern is controlled by variations in the wind.
