Dataset description: Oceanographic time-series monitoring data of a shallow-water placement of dredged sediment in south San Francisco Bay, California, 2023-2025

Oceanographic and meteorological time-series monitoring data were collected by the U.S. Geological Survey (USGS) Pacific Coastal and Marine Science Center from 2023 to 2025, to monitor a pilot shallow-water placement of dredged sediment project led by the US Army Corps of Engineers San Francisco District. Data were collected at nine stations located in the shallows offshore of Whales Tail Marsh in south San Francisco Bay, CA. Stations were positioned around the placement site of the dredged material. Data were collected prior to, during, and after the sediment was placed. Stations consisted of platforms deployed along 2 transects: one along-shore and one cross-shore. Stations in the cross-shore transect included: XM, located approximately 25 meters from the bay edge on Whales Tail marsh; X4 located slightly offshore of the marsh; X3 just offshore (west) of X4; X2 (same location as XG and XL) east/marsh side of the placement area; X1 western side of the placement area; and X0 just east of the navigational channel. A wave-met buoy MW was close to and slightly east of X0. Along-shore transect platforms included AN and AS, north and south of the placement area, respectively. Data types include pressure, velocity, turbidity, suspended particle size distribution, conductivity, temperature, wave statistics, and wind speed and direction, barometric pressure and air temperature.
