Potential Methane Production and Oxidation Rates and Porewater Chemistry Across Peatland Hummocks and Lawns

This dataset contains potential methane (CH₄) production and oxidation rates and porewater chemistry (dissolved oxygen, pH, redox potential, dissolved CH₄, and CH₄ stable isotopes) measurements collected from hummocks and lawns in a poor fen in New Hampshire, USA. Potential CH₄ production and oxidation rates determined via incubations and dissolved oxygen measurements were collected in July 2018. Porewater CH₄ concentration, δ¹³C-CH₄ and δD-CH₃D, and Eh/pH were collected in July/August 2020. The data file contains a "README" tab with a guide for variable units and descriptions.本数据集涵盖采自美国新罕布什尔州一处贫营养泥炭沼泽（poor fen）的泥炭丘与草甸生境的潜在甲烷（CH₄）产生速率、氧化速率，以及孔隙水化学组分（溶解氧、pH、氧化还原电位、溶解态甲烷及甲烷稳定同位素）的测定数据。其中，通过孵育实验（incubations）测得的潜在甲烷产生与氧化速率、溶解氧测定数据采集于2018年7月；孔隙水甲烷浓度、δ¹³C-CH₄与δD-CH₃D同位素组成，以及Eh/pH数据则采集于2020年7月至8月。数据文件包含标注为"README"的标签页，其中提供了变量单位与说明指南。
