Dataset: Climate-induced shifts in sulfate dynamics regulate anaerobic methane oxidation in a coastal wetland, 2022, Maryland.

This dataset accompanies the paper Lee et al. currently under review at Science Advances. The data are from a multi-year field manipulation of warming and elevated CO₂ (SMARTX) in the Smithsonian's Global Change Research Wetland (GCReW), a brackish, microtidal wetland site on a subestuary of the Chesapeake Bay. These data were generated to understand how warming and elevated CO₂ drive anaerobic methane (CH₄) oxidation. The dataset includes soil redox potential, CH₄emissions, porewater sulfate and chloride, root productivity, rates of sulfate-dependent anaerobic CH₄, and ANME abundance. Metadata are provided in the Read Me file.

本数据集配套于Lee等人目前正在《Science Advances》（《科学进展》）审稿阶段的研究论文。本次实验数据采集自史密森学会全球变化研究湿地（Smithsonian's Global Change Research Wetland, GCReW）内开展的增温与高浓度CO₂野外多年操控实验（SMARTX）；该湿地为坐落于切萨皮克湾支流河口的微潮汐咸淡水生境。本数据集的构建旨在阐明增温和高浓度CO₂如何驱动厌氧甲烷（CH₄）氧化过程。数据集包含土壤氧化还原电位、甲烷（CH₄）排放通量、孔隙水硫酸盐与氯化物含量、根系生产力、硫酸盐依赖型厌氧甲烷氧化速率，以及厌氧甲烷氧化古菌（Anaerobic Methane-oxidizing Archaea, ANME）的丰度。元数据详见Read Me文件。
