[Carbonate rock species composition] - Carbonate rock species composition from samples collected by HOV Alvin during R/V Atlantis cruises AT37-13 and AT42-03 and ROV SuBastian during R/V Falkor cruise FK190106 at Pacific margin of Costa Rica from 2017 to 2019 (Collaborative research: Quantifying the biological, chemical, and physical linkages between chemosynthetic communities and the surrounding deep sea)

This dataset is a matrix of individuals counts of species by sample of carbonate rocks collected by HOV Alvin during R/V Atlantis cruise AT37-13 (2017) and AT42-03 (2018) and ROV SuBastian during R/V Falkor cruise FK190106 (2019) at the Quepos Landslide, Mound 12, and Jaco Scar methane seeps in the Pacific margin of Costa Rica. It includes cruise, dive, collection, and sample information, as well as the description of seep location and activity level and description of treatment (in situ, colonization, or transplant).
