Ferreira, J. C. T.; Mcgill, S. C.; Tan, A. C.; Lacy, J. R. 2023. Grain size, bulk density, and carbon content of sediment collected from Whale's Tail South marsh and adjacent bay floor, South San Francisco Bay, California, 2021-2022. U.S. Geological Survey.

Sediment samples were collected on and adjacent to the Whale’s Tail South marsh. Short push-cores of bed sediment were collected in South San Francisco Bay adjacent to Whales Tail South marsh on five days from June through August 2021 and 3 days from November 2021 to January 2022. Additional samples were taken from ceramic tiles placed on the marsh to measure sediment deposition and from rip-up clasts deposited on the marsh edge. Samples were analyzed for sediment properties including bulk density, particle size distribution, and percent carbon. These data were collected as part of a collaborative study with the USGS Western Ecological Research Center to quantify sediment fluxes, deposition on the marsh, and changes in marsh morphology at Whale's Tail marsh in southern San Francisco Bay.

Ferreira, J. C. T.; Lacy, J. R.; Mcgill, S. C.; WinklerPrins, L. T.; Nowacki, D. J.; Stevens, A. W.; Tan, A. C. 2023. Hydrodynamic and sediment transport data from Whale's Tail marsh and adjacent waters in South San Francisco Bay, California 2021-2022. United States Geological Survey.

The U.S. Geological Survey Pacific Coastal and Marine Science Center collected hydrodynamic and sediment-transport data at shallow water sites in South San Francisco Bay and in the Whale's Tail South marsh in Eden Landing Ecological Reserve in Alameda County, CA in 2021 and 2022. This data release includes hydrodynamic and sediment transport time-series data spanning from June 2021 to January 2022, as well as sediment bed properties and water column suspended-sediment concentrations Details on station location, instrumentation, and measured variables are included in sections for each data type. The data were collected to determine sediment supply and sediment delivery to marshes, both in the bay and in tidal creeks as well as across the bay-marsh interface during varying tidal and wave conditions. The goal of the project was to more accurately predict the fate of marshes and to optimize management actions. They 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.
