    • Grain size and bulk density of sediment cores from Little Holland Tract and Liberty Island, Sacramento-San Joaquin Delta, California, 2016 (ver. 2.0, March 2025)

    Metadata Updated: July 24, 2025

    Grain size distribution, bulk density, and percent carbon are reported for sediment push cores from two flooded agricultural tracts, Little Holland Tract and Liberty Island, in the Sacramento-San Joaquin Delta, California. Push core samples were collected from 17 sites by the U.S. Geological Survey in June 2016. Each core was analyzed at multiple depths to investigate variations in particle sizes with depth below the sediment surface. The same sites were sampled previously in 2014 (https://www.sciencebase.gov/catalog/item/5a73a58fe4b0a9a2e9e172cf). These data provide insight into the variation of particle size distributions in space, bed depth, and time.
