This report presents data collected for two U.S. Geological Survey field sampling projects related to mercury (Hg) in Sinclair Inlet: (1) the Watersheds Sources Project that evaluated sources of Inlet during December 2007 March 2010, and (2) Methylation Bioaccumulation Project, a comprehensive examination biogeochemistry sediment, water, zooplankton August 2008–February 2010. For Watershed project, nonpoint point from Bremerton naval complex (BNC) were by using filtered total particulate measured water samples 11 wells, 2 dry dock sump discharges, steam plant's effluent at BNC. Methylmercury inlet examined determining methylmercury concentrations five effluent, intertidal piezometers, three stormwater drains on BNC, as well creeks, wastewater treatment facilities, watershed outside An improved understanding tidally modulated migration BNC was gained through intensive nearshore (tidal) events species groundwater nearby drain.
