Chemical composition of diffuse flow vent fluids collected from the Crab Spa site at East Pacific Rise during the AT26-10 oceanographic expedition, Jan. 2014 (Microbial Communities at Deep-Sea Vents project)

Abstract

This dataset includes chemical composition (Cl, SO4, Na, K, Mg, and Ca concentrations) of diffuse flow vent fluids collected from the Crab Spa (9.8398º N, 104.2913º W) site at East Pacific Rise during the RV/Atlantic AT26-10 oceanographic expedition, Jan. 2014. Samples were collected at 2500 m depth by using isobaric gas-tight samplers (IGT, WHOI). Upon transfer onboard R/V Atlantis, the sampled diffuse flow fluids were incubated at 250 bars. Refer to the dataset https://www.bco-dmo.org/dataset/628993 for information regarding these incubations. For a complete list of measurements, refer to the supplemental document 'Field_names.pdf', and a full dataset description is included in the supplemental file 'Dataset_description.pdf'.
