SPRUCE Does dissolved organic matter or solid peat fuel anerobic respiration in peatlands?: Supporting Data

Hopple et al. (2019) investigated whether, as a primary substrate - dissolved organic matter (DOM) or solid peat - was driving anaerobic respiration at surface and at deep depth increments within two bogs and a poor fen in northern Minnesota. To address this question, they used a combination of soil laboratory incubations, as well as in-situ analyses of porewater dissolved organic carbon (DOC) concentrations and specific UV absorbance (SUVA) measurements. Soil samples were collected in June 2013 and July 2014, while porewater samples were taken in July 2013. Data provided include: porewater DOC concentration and SUVA values, soil CH4 and CO2 potential production rates from peat samples exposed to varying DOM concentrations, and soil CH4 and CO2 potential production rates.These data are provided in support of the publication: Does dissolved organic matter or solid peat fuel anerobic respiration in peatlands? (Hopple et al., 2019). This dataset contains four files in comma separate (*.csv) format.

Hopple等人（2019）探究了以溶解态有机质（dissolved organic matter, DOM）或固态泥炭作为主要底物时，是否会驱动明尼苏达州北部两处沼泽与一处贫营养泥炭沼泽的表层及深层剖面的厌氧呼吸过程。为解答该研究问题，研究团队结合了土壤实验室培养实验，以及孔隙水溶解有机碳（dissolved organic carbon, DOC）浓度的原位分析与特异性紫外吸收（specific UV absorbance, SUVA）测定。土壤样品采集于2013年6月与2014年7月，孔隙水样品则采集于2013年7月。本次提供的数据包括：孔隙水DOC浓度与SUVA值、暴露于不同DOM浓度的泥炭样品的土壤CH4与CO2潜在产率，以及土壤CH4和CO2潜在产率。本数据集为以下发表论文提供数据支撑：《溶解态有机质与固态泥炭何者为泥炭地厌氧呼吸供能？》（Hopple等，2019）。本数据集包含4个逗号分隔格式（*.csv）的文件。
