SPRUCE Phospholipid Fatty Acid (PLFA) Abundances, August 2021-June 2022

This data set provides the results for phospholipid fatty acid analysis (PLFA) of peat samples collected from ambient plots in the SPRUCE experiment site, with experimental plot samples still being processed. The samples used to generate this data set were collected on 2021-08-23 and 2022-06-21. This data set includes abundances for groups of lipids indicating total biomass, fungi, Gram-positive bacteria, Gram-negative bacteria, actinomycetes, and anaerobic bacteria. This data set contains one file in comma separate (*.csv) format.

Samples: On each sampling date, cores extending to 200 cm were collected and subsampled at 10 cm intervals from 0 and 100 cm and 25 cm intervals below 100 cm depth in Plot 7 and 21. During the lipid extraction procedure, samples were pooled into the following depth increments in order to obtain sufficient material to achieve adequate lipid yield: 0-10, 10-20, 20-30, 30-50, 50-100, and 100-150, and 150-200 cm.

本数据集提供了SPRUCE实验站点对照样地泥炭样品的磷脂脂肪酸分析（phospholipid fatty acid analysis, PLFA）结果，当前实验样地样品仍处于处理流程中。用于构建本数据集的样品采集于2021年8月23日与2022年6月21日。本数据集包含多组脂质的丰度数据，这些脂质分别指示总生物量、真菌、革兰氏阳性菌、革兰氏阴性菌、放线菌以及厌氧菌。本数据集包含1个逗号分隔格式（*.csv）的文件。

采样详情：在每个采样日期，研究人员于7号与21号样地采集深度达200 cm的泥炭岩心，并按以下规则分样：0~100 cm深度区间以10 cm为间隔进行分样，100 cm以下深度区间则以25 cm为间隔分样。在脂质提取流程中，为获取足量样品以达到合格的脂质提取产率，样品被合并至以下深度区间：0-10 cm、10-20 cm、20-30 cm、30-50 cm、50-100 cm、100-150 cm以及150-200 cm。
