Summary
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.

Hydrodynamic time-series data from Whale's Tail South marsh in Eden Landing Ecological Reserve in Alameda County, CA in 2021 and 2022
Hydrodynamic and sediment transport time-series data, including water depth, velocity, turbidity, conductivity, and temperature, were collected by the U.S. Geological Survey (USGS) Pacific Coastal and Marine Science Center 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. Data files are grouped by data type and season (summer and winter). At Bay sites, instruments were deployed on small quadpods. In the tidal creek, instruments were attached to grates mounted directly on the sediment bed. Marsh sites consisted of one transect of six stations perpendicular to the bay-marsh interface, and a second transect perpendicular to a tidal creek. Note that marsh stations were positioned fairly high in the tidal frame (close to the mean higher-high water elevation), so they were inundated less than 10 percent of the time. Instruments at the Bay stations were inundated most of the time but were subaerial at low tide. Data are only valid when the instruments were submerged. Users are advised to assess data quality carefully, and to check metadata for instrument information, as platform deployment times and data-processing methods varied.

Topographic data from Whale's Tail marshes, South San Francisco Bay, California, 2021-2022
Topographic data were collected in the Whale's Tail marsh in southern San Francisco Bay between December 2021 and January 2022. The topographic data were acquired using global satellite navigation system receivers mounted on backpacks and hiked over the marsh surface.

Profiles of salinity, temperature, depth, turbidity, and distributions of particle size in suspension collected during four days in South San Francisco Bay, California, June 2021 to January 2022
Profiles of salinity, temperature, turbidity, and particle size distribution were collected by the U.S. Geological Survey (USGS) Pacific Coastal and Marine Science Center in South San Francisco Bay. Data were collected at depth intervals ranging between 0.5 and 2 m (depending on total water depth); sensors remained at each depth for 1-2 minutes. Each profile was collected from surface to bed, and the near-surface region was sampled again at the end of the profile to check steady-state conditions. Profiles were collected on 4 days: June 22, July 21, and December 3 of 2021, and on January 4, 2022 (UTC). Data files are grouped by season (summer or winter) and by instrument (CTD or LISST). No LISST data were collected in the winter. Users are advised to assess data quality carefully.

Suspended sediment concentrations from water samples collected in South San Francisco Bay, California, and adjacent tidal creeks, Summer 2021
Water samples were collected in South San Francisco Bay and Whale's Tail South marsh tidal creeks from June 2021 through September 2021. The water samples were collected near pre-established USGS instrument moorings with a peristaltic pump, via a Niskin bottle, or directly with a sample bottle to analyze for suspended sediment concentration.
