Porewater geochemistry, including methane, CO2, sulfate, and sulfide from Guaymas Basin hydrothermal sediments collected on R/V Atlantis cruise AT15-56 in Nov-Dec 2009
Abstract:
Porewater geochemistry of Guaymas Basin hydrothermal sediments (Southern Spreading segment, 27°00.44'N and 111°24.55'W, 2000 m water depth) including methane, CO2, sulfate, and sulfide, were measured during R/V Atlantis cruise AT15-56 to Guaymas Basin in 2009. Sampling was conducted on Alvin dives 4562 to 4573. The association of bacterial and archaea communities with hydrothermal seepage and the habitat preferences of various types of microbes were investigated by geochemical and microbiological characterization of hydrothermally active sediments in combination with temperature measurements down to 40 centimeters (cm) sediment depth. This dataset includes sulfide, sulfate, dissolved inorganic carbon (DIC), delta 13C-DIC, methane, delta 13C-methane, and VFAs. Corresponding temperature gradients of hydrothermal sediments for Alvin dives during AT15-56 are available at
