Gastropod counts by species collected from inactive sulfides on the East Pacific Rise during R/V Roger Revelle cruise RR2102 in April 2021 and R/V Atlantis cruise AT50-06 in December 2022

This dataset provides counts by species for gastropods collected mainly from rock grabs at two inactive sulfide mounds (Lucky’s Mound and Sentry Spire) near 9°47’N on the East Pacific Rise. Sampling was conducted on dives with HOV Alvin during R/V Atlantis cruise AT50-06 in December 2022 and with ROV Jason during R/V Roger Revelle cruise RR2102 in April 2021. Specimens were preserved in ethanol or fixed in formalin. Gastropods were identified morphologically to species (with genetic sequences obtained for a subset); two of the species were new to science as described by Chen et al. (2024). Counts are not comprehensive thus cannot be used for quantitative analyses. This dataset is derived from Beaulieu et al. (2024) doi:10.26008/1912/bco-dmo.946438.1, and funding was from NSF OCE-2152453.
