Invertebrate stable isotopes from samples collected at methane seeps off Southern California with the HOV Alvin from July 16-28, 2023 during R/V Atlantis cruise AT50-12

This dataset provides C and N stable isotope data for invertebrates collected by HOV Alvin from July 16-28, 2023 at methane seeps in Southern California during R/V Atlantis cruise AT50-12. There are also POC data for one surface and one near bottom water sample collected by CTD. δ13C and δ15N measurements were made on 0.2-4 mg dry-weight samples combusted using an elemental analyzer interfaced to a continuous flow isotope ratio mass spectrometer at the Stable Isotope Facility at the University of California, Davis (SIF-UCD).
