| Description |
Bed sediment samples were collected from the intertidal, and subtidal shallows of San Pablo Bay National Wildlife Refuge and Corte Madera Bay near stations where instrumented platforms that were collecting hydrographic time-series were deployed. Sediment sediments were collected with push cores, either manually or by subsampling a Gomex box corer. Cores, which ranged in length from 5 to 18 centimeters (cm), were sectioned by depth. The top two sections from each core were 0.5 cm thick, the following sections were 1 cm thick, sections below 6 cm were often sectioned either into sections that were 1 or 2 cm thick. Additional samples were taken from sediment deposited on ceramic tiles attached to the marsh surface. Samples were analyzed for sediment properties including bulk density, particle size distribution, loss on ignition, and percent carbon. [More]
