Description:

Abstract:

Profiles of salinity, temperature, turbidity, and particle size distribution were collected by the U.S. Geological Survey (USGS) Pacific Coastal and Marine Science Center at two locations 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 minute. 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 for 4 days, for about 7.75 hours each day: Jul 21, 22, 24, and 28, 2020. Data files are grouped by site (channel or shallows) and by instrument (CTD or LISST). Users are advised to assess data quality carefully, and to check metadata for instrument information.

Purpose:

These data were collected to reveal particle size distributions through the water column, along with vertical suspended sediment concentration, salinity, and temperature variation. They were collected as part of a collaborative study funded by the San Francisco Estuary Institute on tidal controls of suspended particle size in South San Francisco Bay. These data are intended for researchers, students, policy makers, and the general public.

Process_Description:

Files were named with a convention that uses a 14-digit alpha-numeric code. The first three characters for this dataset are all 'CSF' for the experiment name; the fourth and fifth positions represent the calendar year in which the first data point in the file was taken (20, 2020); the sixth, seventh and eighth characters are an alphanumeric code for the sample type (profiles, PRO). The ninth and tenth characters represent the time index of the profile, starting at 01 for the first profile, and ending at 52 for the last one. The eleventh to twelfth or thirteenth characters are "ls" or "ctd" for the Sequoia Scientific LISST-200X or RBR CTD. The last two characters are "-s" or "-c" for the shallows or channel location.
