    • Sediment grain-size data from vibracore samples collected offshore San Francisco, California, during field activity 2019-649-FA from 2019-10-11 to 2019-10-18

    Metadata Updated: October 29, 2025

    This section of the data release contains grain-size and total organic carbon (TOC) analyses of 132 samples taken from vibracores that were collected aboard the R/V Bold Horizon in 2019 on U.S. Geological Survey Field Activity 2019-649-FA offshore San Francisco, California. The samples were analyzed for percent weight of grain size and total organic carbon. The samples were taken at approx. 50 cm intervals from (and including) the core-catcher, which represents the bottom of the core.
