Volatile fatty acids and alcohols concentrations, stable carbon isotopic compositions, and metabolic rates in hydrothermally altered sediments data collected aboard R/V Atlantis cruise AT37-06 in the Guaymas Basin, the Gulf of California from 2016-12-18 to 2016-12-24

Volatile fatty acids and alcohols concentrations, stable carbon isotopic compositions and metabolic rates in hydrothermally altered sediments data collected aboard R/V Atlantis cruise AT37-06 in the Guaymas Basin, the Gulf of California from 2016-12-18 to 2016-12-24 at six sampling stations. The purpose of this cruise was to understand the generation and utilization of volatile fatty acids and alcohols in hydrothermally altered sediments of the Guaymas Basin. The data includes information about the sampling stations (coordinates, date and dive number), geochemistry data (dissolved inorganic carbon, dissolved organic carbon, methanol, ethanol, and the concentration and isotopic compositions of formate, acetate, and lactate), methanogenesis and oxidation rate for acetate and methanol, and the inhibition experiment results. The R/V Atlantis cruise AT37-06 purpose was to sample the microbial carbon cycling and its interactions with sulfur and nitrogen transformations in the Guaymas Basin hydrothermal sediments. The research cruise left Manzanillo, Mexico on 2016-12-09 and returned 2016-12-27 and it was lead by Chief scientist Andreas Teske.
