| Hydrodynamic time-series data from Whale's Tail South marsh in Eden Landing Ecological Reserve in Alameda County, CA in 2021 and 2022 |
Moorings - Tripods |
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. |

| Grain size, bulk density, and carbon content of sediment collected from Whales Tail South marsh and adjacent bay floor, South San Francisco Bay, California, 2021-2022 |
Push corer |
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 Whale's 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 sediment deposited on ceramic tiles attached to the marsh surface 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. |

| 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 |
watersamples |
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. |

| Percent sand and fines in suspended sediment from water samples from South San Francisco Bay, California, 2021 |
watersamples |
Water samples were collected in South San Francisco Bay adjacent to Whale's Tail South marsh on three days from June through December 2021 to analyze for suspended-sediment concentration and the percent of sand and fines in suspended sediment. |
