The effects of key environmental variables (temperature, pH, H2S, SO42-, DOC) on sulfate reduction rates in material recovered from a hydrothermal flange from the Grotto edifice in the Main Endeavor Field, Juan de Fuca Ridge. Sulfate reduction was measured in batch reactions across a range of physico-chemical conditions. Temperature and pH were the strongest stimuli, and maximum sulfate reduction rates were observed at 50 degrees celsius and pH 6.
Information for this dataset was derived from single massive piece of hydrothermal deposit (approximately ~100 kg in weight) that was recovered from a flange on the Grotto vent (47.949, -129.098) at a depth of 2188.3 m (Dive J2-575, AT-18-08, R/V Atlantis) and brought up to the surface in the basket of the ROV Jason II.
Analysis and write-up of these data are found in Frank et al., 2015
