Sediment core data collected from Cargill Marsh, South San Francisco Bay, California during field activities 2022-643-FA and 2023-681-FA

The U.S. Geological Survey Pacific Coastal and Marine Science Center collected cores in the Cargill Marsh section of Whales Tail South Marsh in Eden Landing Ecological Reserve in Alameda County, California in 2022 and 2023. This data release includes photographs, computed tomography (CT) scans, and radiometric data. Details on core locations and measured variables are included in sections for each data type. The data were collected to determine sediment supply and sediment delivery to marshes over decadal time scales. The goal of the project was to more accurately predict the fate of marshes and to optimize management actions. 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.
