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.
