    • Zooplankton Survey of the Northern Sacramento-San Joaquin Delta, California, 2016-2018

    Metadata Updated: February 22, 2025

    This data set contains information on zooplankton and associated environmental parameters for sampling conducted in California's northern Sacramento-San Joaquin Delta between May 2016 and April 2018. Macrozooplankton were sampled with horizontal tows (water surface) of a 50 cm-diameter conical plankton net that was 150cm long with 102µm mesh. Samples were preserved in the field in 10% formalin for laboratory processing that was conducted by a contractor (EcoAnalysts, Inc). Due to processing limitations, taxonomic data is not available for every sample and are thus not reflected in every data table (samples 1-28, 318-328, 531-620 have no data in the Zooplankton Taxa Table)
