    • Sediment biogeochemistry and mercury measurements from wetlands of the San Francisco Bay, CA

    Metadata Updated: September 17, 2025

    Habitat biogeochemistry was assessed by measuring 31 variables in sediments, porewater, and surface waters related to mercury content, organic matter, sediment characteristics, and microbial rates of sulfate reduction, iron reduction, and methanogenesis. Fifty-six composite surface (0-2 cm) sediment cores and 32 surface water samples were collected in three wetlands in the spring and summer of 2005 and 2006.
