Suspended sediment concentrations from water samples collected from the shallows and a tidal creek of Northern San Francisco Bay, California, 2022-2023

공공데이터포털

Water samples were collected in San Pablo Bay, Corte Madera Bay, and a tidal creek in Corte Madera Marsh between April 2022 and June 2023 to measure suspended-sediment concentrations and percent carbon of suspended sediment. The water samples were collected near the USGS instrument platforms (see time-series data page) with a peristaltic pump, via a Niskin sampler, or directly with a sample bottle.

Suspended sediment concentrations from water samples collected in South San Francisco Bay, California, and adjacent tidal creeks, Winter 2021-2022

공공데이터포털

Water samples were collected in South San Francisco Bay and Whale's Tail South marsh tidal creeks from November 2021 through February 2022. 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.

Suspended sediment concentrations from water samples collected in south San Francisco Bay, California, 2023-2024

공공데이터포털

Water samples were collected in south San Francisco Bay between August 2023 and August 2024 to measure suspended sediment concentration. The water samples were collected near USGS instrument platforms (see time-series data page) with a peristaltic pump. The suspended sediment concentrations of the samples were determined at the USGS Pacific Coastal and Marine Science Center sediment lab. Measured suspended sediment concentrations were used to calculate calibration coefficients that can be used to convert time series of turbidity data to time series of suspended sediment concentrations. These calibration coefficients can be found in file: DMP23_Turbidity_to_SSC_calibration_constants.csv, one of the support files for the time-series data section of this data release.

공공데이터포털

Water samples were collected in San Pablo Bay and Grizzly Bay on five days from January through June 2020. The water samples were collected from a small vessel near pre-established USGS instrument moorings using a peristaltic pump or a Niskin bottle. Data are provided in a comma-delimited values spreadsheet.
