Sulfate reduction energetics at Main Endeavor grotto chimney from samples collected on RV Atlantis (AT18-08) during Jason II dives in the Juan de Fuca Ridge from July to August 2011

<p>The effects of key environmental variables (temperature, pH, H2S, SO42-, DOC) on sulfate reduction energetics 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&nbsp;physico-chemical&nbsp;conditions. Temperature and pH were the strongest stimuli, and maximum sulfate reduction rates were observed at 50 degrees celsius and pH 6.</p>

<p>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&nbsp;vent&nbsp;(47.949, -129.098) at a depth of 2188.3 m (Dive J2-575, AT-18-08,&nbsp;R/V Atlantis) and brought up to the surface in the basket of the&nbsp;ROV Jason II.&nbsp;</p>

本数据集聚焦关键环境变量（温度、pH、硫化氢（H₂S）、硫酸根（SO₄²⁻）、溶解有机碳（dissolved organic carbon, DOC））对胡安·德富卡海脊主奋进区Grotto构造热液凸缘回收样品中硫酸盐还原能学的影响。研究通过批量反应体系，在一系列物理化学条件下测定了硫酸盐还原活性。结果表明，温度与pH是最显著的调控因子，硫酸盐还原速率在50℃、pH 6时达到峰值。

本数据集的样品源自一块重达约100千克的大型热液沉积物，该样品采自Grotto喷口（47.949, -129.098）处的热液凸缘，采样水深为2188.3米，对应下潜任务编号为J2-575、AT-18-08，搭载平台为“亚特兰蒂斯号”（R/V Atlantis）研究船，由遥控无人潜水器（Remotely Operated Vehicle, ROV）杰森二号（Jason II）的采样篮回收至海面。

本数据集的研究方法源自Frank等人2015年的研究成果。
