Data were collected at one site in San Pablo Bay and one site in Grizzly Bay from June through August 2019, by deploying a Sequoia Scientific Laser In-situ Scattering and Transmissometry instrument (LISST 100x) from a small vessel near pre-established USGS instrument moorings. At both sites, data were collected on six dates at three depths, generally near the water surface, at mid depth, and near the sediment bed, for 1-3 minutes at each depth. LISST volume concentrations are most accurate when the optical percent transmission is above 30, as light passing through the sample volume is unlikely to be scattered by more than one particle. One file (ERO19PBP04) was removed due to poor data quality throughout the file. These files contain all samples collected; judgment should be applied when using them. Users are advised to check metadata and instrument information carefully for applicable time periods of specific data. Purpose: These data were collected for the purpose of estimating particle settling velocity. 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.

Browse_Graphic_File_Type: JPEG Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: No formal attribute accuracy tests were conducted. Logical_Consistency_Report: No formal logical accuracy tests were conducted. Data fall within expected ranges. Completeness_Report: Dataset is considered complete for the information presented, as described in the abstract. Users are advised to read the rest of the metadata record carefully for additional details. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Horizontal accuracy derived from the boat’s GPS instrumentation is less than 5 m. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: Vertical positioning is reported within each data file as pressure from the water surface. Accuracy depends on the presence of waves, and calibration and sensitivity of the pressure sensor, and resulted in combined uncertainty of about 15 cm. Depth above bottom can be computed by referencing the collection time and the total water depth reported in the time series files. Lineage: Process_Step: Process_Description: Profiles were collected in Grizzly Bay and San Pablo Bay using the Sequoia Scientific LISST-100X, near the Grizzy Bay Mooring site (GBM) and the San Pablo Bay Mooring site (PBM). Process_Date: 20190815 Process_Step: Process_Description: Data were accumulated into NetCDF files. Out-of-water data were removed from the files. Process_Date: 20201023 Process_Step: Process_Description: Files were named with a convention that uses a 12-digit alpha-numeric code. The first three characters for this dataset are all 'ERO' for the experiment name; the fourth and fifth positions represent the calendar year in which the first data point in the file was taken (19, 2019); the sixth and seventh characters are an alphanumeric code for the embayment (for example, GB refers to Grizzly Bay) the eighth character is 'P', to represent the method of collection used (Profiling). The ninth and tenth characters represent the time index of the profile, starting at 01 for the first profile, and ending at 06 for the last one. The eleventh and twelfth characters are "ls" for the Sequoia Scientific LISST-100X. Data from San Pablo Bay and data from Grizzly Bay are provided in separate zip files.
