Summary
The U.S. Geological Survey Pacific Coastal and Marine Science Center collected hydrodynamic and sediment-transport data at shallow water sites in San Pablo Bay and Grizzly Bay, in northern San Francisco Bay between January and September 2020. The data were collected to determine hydrodynamic forcing, bed roughness, suspended-sediment concentration, and physical properties of the sediment bed. This data release includes hydrodynamic and sediment transport time-series data spanning from January to June 2020, as well as sediment bed properties and water column suspended-sediment concentrations collected on eight days from January to September 2020. Details on station location, instrumentation, and measured variables are included on pages [...]
Summary
The U.S. Geological Survey Pacific Coastal and Marine Science Center collected hydrodynamic and sediment-transport data at shallow water sites in San Pablo Bay and Grizzly Bay, in northern San Francisco Bay between January and September 2020. The data were collected to determine hydrodynamic forcing, bed roughness, suspended-sediment concentration, and physical properties of the sediment bed. This data release includes hydrodynamic and sediment transport time-series data spanning from January to June 2020, as well as sediment bed properties and water column suspended-sediment concentrations collected on eight days from January to September 2020. Details on station location, instrumentation, and measured variables are included on pages for each data type. These data were collected as part of a collaborative project with the USGS California Water Science Center and the USGS Water Mission Area who collected erodibility and benthic infauna data. The goal of the project was to determine physical and biological controls on sediment erodibility in San Francisco Bay. Funding was provided by the USGS Priority Ecosystems Studies Program for San Francisco Bay and Delta and the USGS Coastal and Marine Hazards and Resources Program.

Purpose
The purpose of this project is to investigate the effects of spatial and temporal variation in physical and biological properties of the sediment bed on erodibility. Results will be used to advance understanding of resuspension and sediment-transport dynamics for cohesive sediments, and to improve the parameterization of variables used in numerical sediment transport models. In San Francisco Bay, sediment transport plays a critical role in marsh restoration, the fate of disposed dredge material, contaminant transport, and geomorphic response to sea-level rise. These data are intended for researchers, students, policy makers, and the general public.
