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实验采集样本的大规模野外实测与实验室分析结果。结果表明，对厚度超过2米的泥炭层实施生态系统尺度增温，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。多项证据链——包括培养实验以及碳14（¹⁴C）、溶解气体、微生物群落代谢潜能的原位分析——均证实，甲烷排放的提升源于地表过程，而非深层埋藏碳的降解。本次提供的配套数据包含用于生成论文正文6幅主图与12幅补充图表的汇总整合数据集。
