Grain size, bulk density, and carbon content of sediment collected from Whale's Tail South marsh and adjacent bay floor, South San Francisco Bay, California, 2021-2022 (ver. 2.0, March 2025)

Sediment samples were collected on and adjacent to the Whale's Tail South marsh. Short push-cores of bed sediment were collected in South San Francisco Bay adjacent to Whale's Tail South marsh on five days from June through August 2021 and 3 days from November 2021 to January 2022. Additional samples were taken from sediment deposited on ceramic tiles attached to the marsh surface and from rip-up clasts deposited on the marsh edge. Samples were analyzed for sediment properties including bulk density, particle size distribution, and percent carbon.
