SPRUCE 13C-Phospholipid Fatty Acid (13C-PLFA) Abundances, June 2014-June 2015

This data set provides the results of 13C phospholipid fatty acid analysis (13C-PLFA) of peat samples collected from ambient and experimental plots in the SPRUCE experiment site. The samples used to generate this data set were collected just prior to initiation of deep peat heating (DPH; 03 June 2014), after 3 months (09 September 2014), and after 10 months (16 June 2015). This data set includes the abundances and delta-13C isotopic signatures of individual lipids and of groups of lipids indicating total biomass, fungi, Gram-positive bacteria, Gram-negative bacteria, actinomycetes, and anaerobic bacteria. This dataset contains two files in comma separate (*.csv) format. Cores extending to 250 cm (200 cm in June 2015) were collected and subsampled at 10 cm intervals from 0 and 100 cm and 25 cm intervals below 100 cm depth. During the lipid extraction procedure, samples were pooled into the following depth increments in order to obtain sufficient material to achieve adequate lipid yield: 0-20, 20-50, 50-100, 100-150, 150-200, and 200-250cm.

本数据集提供了来自SPRUCE实验站点的对照样地与处理样地泥炭样品的13C磷脂脂肪酸分析（13C-PLFA）结果。用于构建本数据集的样品采集时间点分别为深层泥炭加热（DPH）启动前夕（2014年6月3日）、加热3个月后（2014年9月9日）以及加热10个月后（2015年6月16日）。本数据集涵盖了各类单体脂质以及指示总生物量、真菌、革兰氏阳性菌、革兰氏阴性菌、放线菌与厌氧菌的脂质组的丰度与δ13C同位素特征。本数据集包含两份逗号分隔值（*.csv）格式文件。采集的岩芯深度可达250 cm（2015年6月的采样岩芯为200 cm），其中0~100 cm深度以10 cm为间隔分样，100 cm以下深度则以25 cm为间隔分样。在脂质提取流程中，为获取足够样品以获得合格的脂质提取产率，样品按以下深度区间合并：0~20 cm、20~50 cm、50~100 cm、100~150 cm、150~200 cm以及200~250 cm。
