Field Activity 2022-619-FA

Identifier 2022-619-FA
Alternate names NBM22
Purpose To investigate the influence of tides, waves, and water levels on near-marsh suspended sediment concentration (SSC) and deposition on tidal marsh surfaces.
Location Corte Madera Marsh and San Pablo Bay National Wildlife Refuge, California
Summary Water samples were collected and analyzed for suspended sediment concentrations, sediment grabs were collected and analyzed for bulk density, grain size, and carbon. Tidal creek discharge was measured. Additionally, hydrodynamic data including current velocities, pressure, temperature, salinity, were collected at locations in the subtidal and intertidal shallows of San Pablo and Corta Madera Bays, and within a tidal creek in Corta Madera marsh. A marsh top sensor collected pressure and turbidity at marshes just inland from the intertidal stations.
