Dataset for: Remarkable capacity for anaerobic oxidation of methane at high methane concentrations

The data contained in this dataset describes anaerobic methane oxidation rates (AOM), sulfate reduction rates (SR), methanogenesis rates, bicarbonate based particulate organic carbon formation rates (bPOC), and methane based particulate organic carbon formation rates (mPOC) from cold seep sediments. Cold seep and hydrothermally altered sediments that were assayed were from the Gulf of Mexico (GoM) aboard R/V Seward Johnson, Monterey Bay (MB) aboard R/V Point Lobos, and Guaymas Basin (GB) aboard R/V Cruise Atlantis 15-56 (AT15-56). Rates were determined by radiotracer techniques or by concentration changes in sulfate. All rates reported were determined for sediments incubated at in situ temperature and pressure.

本数据集包含的数据描述了冷泉沉积物中的厌氧甲烷氧化率（anaerobic methane oxidation rates, AOM）、硫酸盐还原率（sulfate reduction rates, SR）、产甲烷速率、基于碳酸氢盐的颗粒有机碳生成率（bicarbonate based particulate organic carbon formation rates, bPOC）以及基于甲烷的颗粒有机碳生成率（methane based particulate organic carbon formation rates, mPOC）。所分析的冷泉和热液蚀变沉积物样本采集自以下区域：墨西哥湾（Gulf of Mexico, GoM）（搭乘R/V Seward Johnson号科考船）、蒙特利湾（Monterey Bay, MB）（搭乘R/V Point Lobos号科考船），以及瓜伊马斯盆地（Guaymas Basin, GB）（搭乘R/V Atlantis号科考船执行的15-56航次（AT15-56））。这些速率通过放射性示踪技术或硫酸盐浓度变化测定。所有报告的速率均基于在原位温度和压力条件下培养的沉积物样本测定。本数据集为以下研究提供支持：Bowles, Marshall W.、Vladimir A.
