Description:

Abstract:

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.

Purpose:

These data were collected to calibrate turbidity data from optical backscatter sensors to suspended-sediment concentration. They were collected as part of a collaborative study between the USGS Coastal and Marine Hazards and Resources Program, the USGS California Water Science Center, and the USGS Water Resource Mission Area investigating physical and biological controls on bed erodibility. These data are intended for researchers, students, policy makers, and the general public.

Lineage:

Process_Step:

Process_Description:

Water samples were collected from January 2020 to June 2020 using a peristaltic pump or Niskin bottle. Sampling positions were recorded using a hand-held global navigation satellite system (GNSS) receiver. Samples were placed in cold storage until processed.

Process_Date: 20200623

Process_Step:

Process_Description:

The suspended sediment concentrations of the samples were determined in the USGS Pacific Coastal and Marine Science Center sediment lab. Suspended sediment concentrations were determined by a 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: 20200629

Process_Step:

Process_Description:

Suspended sediment concentrations were calculated by subtracting the weight of the filter from the weight of the reweight (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.
