Dataset: Oxygen priming induced by elevated CO2 reduces carbon accumulation and methane emissions in coastal wetlands

This dataset accompanies the published paper Noyce et al. (2022) in Nature Geosciences. 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 side on a subestuary of the Chesapeake Bay. Metadata are provided in the Read Me file. The dataset covers 2017-2020 and includes surface elevation, soil redox potential, methane (CH₄) emissions, porewater CH₄, root biomass, and stem density for each experimental plot.

本数据集配套发表于《自然·地球科学（Nature Geosciences）》的Noyce等（2022）研究论文。数据源自美国史密森学会全球变化研究湿地（GCReW）开展的多年野外增温与CO₂升高操控实验（SMARTX），该湿地为切萨皮克湾次级河口区域的咸淡水微潮湿地片区。元数据详见Read Me文件。数据集涵盖2017至2020年各实验样地的相关数据，包含地表高程、土壤氧化还原电位、甲烷（CH₄）排放、孔隙水甲烷、根系生物量及茎秆密度。
