SPRUCE Stability of Peatland Carbon to Rising Temperatures: Supporting Data

This data set reports the results of extensive field measurements and laboratory analyses of samples from the SPRUCE experiment. Results indicate that ecosystem-scale warming of over 2 m of peat exponentially increased CH4 emissions —but not ecosystem respiration of CO2. Multiple lines of evidence, including incubations and in situ analyses of 14C, dissolved gases, and microbial community metabolic potential, indicate that CH4 emissions increased due to surface processes and not degradation of deeper buried carbon. The supporting data provided include the summarized and aggregated data used to generate the six figures in the main text of the paper and the 12 supplementary figures.

本数据集收录了SPRUCE实验样本的大规模野外实测与实验室分析成果。结果表明，对2米以上泥炭层开展生态系统尺度增温，可呈指数级提升甲烷（CH4）排放，但未对二氧化碳（CO2）的生态系统呼吸产生影响。多组证据——包括培养试验与碳14（14C）、溶解气体、微生物群落代谢潜力的原位分析——证实甲烷（CH4）排放增加源于地表过程，而非深层埋藏碳的降解。本数据集附带的支撑数据包含用于生成论文正文6幅插图与12幅补充插图的汇总整合数据。
