    • Stable carbon and nitrogen isotope data for: 'Ecotoxicoparasitology of the gastrointestinal tracts of pinnipeds: effect of parasites on bioavailability of total mercury (THg)'

    Metadata Updated: October 29, 2025

    This dataset includes stable carbon and nitrogen isotope values for the tissues and parasites of California sea lions and ice seals from California and Alaska coastal waters necropsied and harvested in 2009-2010 respectively. Stable carbon and nitrogen isotope data are useful for clarifying trophic relationships in host-parasite systems. These data were used in tandem with tissue mercury concentrations to explore the role of gastrointestinal parasites on pinniped mercury exposure. There are two files in this dataset: 1) A comma delimited machine-readable file (.csv) that represents the data dictionary, and 2) a comma delimited machine-readable file (.csv) containing the data.
