Properties of sediment collected from channels in northern San Francisco Bay, California, 2024 Gomex Core Bed sediment samples were collected from the channels of 4 sites within northern San Francisco Bay, California, USA. The channels sampled were located in Corte Madera Bay, San Pablo Bay, Grizzly Bay and Suisun Bay. Sediment samples were collected with push cores, by subsampling a Gomex box corer. Cores, which ranged in length from 2 to 6 centimeters (cm), were sectioned by depth. The top two sections from each core were 1 cm thick, the following sections were 2 cm thick. Samples were analyzed for sediment properties including bulk density, particle size distribution, and percent carbon. Samantha C McGill
