The water samples were collected near pre-established USGS instrument moorings with a Niskin bottle, lowered from the R/V Snavely. Data are provided in comma-delimited values spreadsheets. Purpose: These data were collected to calibrate turbidity data from optical backscatter sensors to total suspended solids. Selected samples were also analyzed visually for particle size and settling velocity using the FlocCam. They were collected as part of a study by the USGS Coastal and Marine Hazards and Resources Program, funded by the San Francisco Estuary Institute, investigating physical drivers of sediment flocculation. These data are intended for researchers, students, policy makers, and the general public.

Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: No formal positional accuracy tests were conducted Lineage: Process_Step: Process_Description: Water samples were collected in July, 2020 using a Niskin bottle. Sampling positions were recorded using a boat-mounted global navigation satellite system (GNSS) receiver. Samples were placed in cold storage until processed. Additional video imagery was collected of selected samples consistent with methods for FlocCam analysis. Process_Date: 20200728 Process_Step: Process_Description: The total suspended solids were determined in the USGS Pacific Coastal and Marine Science Center sediment lab. Total suspended solids were determined by filtering a known volume of sample through a pre-weighed filter, which is then dried and reweighed to determine the mass of suspended sediment on the filter. Process_Date: 20200902 Process_Step: Process_Description: Total suspended solids were calculated by subtracting the weight of the filter from the weight of the reweighed (post filtering) filter. The resulting weight (in milligrams) is divided by the volume of sample filtered (in liters) to get the concentration of suspended sediments. Process_Date: 20200902 Process_Step: Process_Description: Particle size, settling velocity, and effective density of individual flocs was computed visually from the video images, consistent with methods for the FlocCam (Manning and Dyer, 2007).
