| Gomex Core | The gomex core was deployed off the Jewel, the core was subsampled once back onboard, using pushcore/syringes. Two cores were collected and subsampled from each Bay. | Geology | 1 |

| Grain size, bulk density, and organic carbon of sediment cores from San Pablo Bay and Grizzly Bay, California, 2020 | Gomex Core | Bed sediment samples were collected in San Pablo Bay and Grizzly Bays on eight days from January through September 2020, to analyze for sediment properties including bulk density, particle size distribution, and percent organic carbon. Sediment samples were collected from a small vessel near pre-established USGS instrument moorings using a Gomex box corer that was subsampled with three push cores (37 mm in diameter) per Gomex core. Six subsamples were collected from the top 5 centimeters (cm) of each push core, a few push cores included the top 8 cm. The top two subsamples were each 0.5 cm thick, and all following subsamples were each 1 cm thick. Push core samples from the first, third, and fifth centimeter depth were analyzed for grain size and percent organic carbon, while all 6 sections were analyzed for bulk density. Data are provided in a comma-delimited values spreadsheet. These data were collected as part of a collaborative project with the USGS California Water Science Center and the USGS Water Mission Area on physical and biological controls on sediment erodibility, funded by the USGS Priority Ecosystems Program for San Francisco Bay and Delta and the USGS Coastal Marine Hazards and Resources Program. | Samantha C McGill |
