Hydrodynamic and sediment transport data from two salt marshes and adjacent shallows in Northern San Francisco Bay, California 2022-2023

The U.S. Geological Survey Pacific Coastal and Marine Science Center collected hydrodynamic and sediment-transport data at shallow subtidal and intertidal sites in Corte Madera Bay and San Pablo Bay National Wildlife Refuge (SPNWF) in San Francisco Bay, CA, as well as on the marsh plain of SPNWF marsh and in a tidal creek and on the marsh plain of Corte Madera Marsh, in 2022 and 2023. This data release includes hydrodynamic and sediment transport time-series data spanning April 2022 to August 2023, as well as sediment bed properties and water column suspended-sediment concentrations (SSC). Details on station location, instrumentation, and measured variables are included in each section. The data were collected to determine the relationship between SSC in the shallows and sediment deposition at two different marshes, during a range of tidal, wave, and hydrologic conditions. The goals of the project are to produce information useful for prioritizing marsh restoration sites, assessing restoration actions, and understanding mechanisms of sediment delivery to marshes. Data were collected as part of a collaborative study with the USGS Western Ecological Research Center. These data are intended for science researchers, students, policy makers, and the general public.
