Benzene polycarboxylic acids, lignin and hydrolysable lipids data from the whole-soil warming experiment at Blodgett Forest, CA, 2018, from: "Rapid loss of complex polymers and pyrogenic carbon in subsoils under whole soil warming"

This data package contains benzene polycarboxylic acids, lignin and hydrolysable lipids data used for the paper: “Rapid loss of subsoil plant-derived polymers and pyrogenic carbon with whole-soil warming”. On April 2018 (after 4.5 years of warming), we collected soil cores down to 90 cm depth from the whole soil profile warming experiment at the University of California Blodgett Forest Research Station, in the Sierra Nevada foothills near Georgetown, CA at 1370 m above sea level. Cores were collected from 6 experimental plots (three replicated blocks); samples were collected in 10 cm increments from 0 to 90 cm depth. This data package includes a file in .csv format and a file in .xlsx format, which can be accessed and processed using MS Excel or R. Benzene polycarboxylic acid, lignin and hydrolysable lipid concentrations are provided as processed data files. The aim of the measurements was to assess how +4°C of whole-soil warming for 4.5 years will affect structurally complex polymeric compounds at different soil depths. The research was supported by Swiss National Science Foundation (SNF) project 172744 (DEEP C) and U.S. Department of Energy, Office of Science, Office of Biological and Environmental Research under contract number DE-AC02-05CH11231.本数据集配套于论文《全土增温下深层土壤植物源聚合物与热解碳的快速流失》（Rapid loss of subsoil plant-derived polymers and pyrogenic carbon with whole-soil warming），包含苯多羧酸（benzene polycarboxylic acids）、木质素（lignin）与水解脂质（hydrolysable lipids）相关检测数据。2018年4月（即持续增温4.5年后），研究团队于加利福尼亚州乔治敦附近内华达山麓、海拔1370米处的加州大学布洛德克特森林研究站全土壤剖面增温实验样地，采集了深度达90厘米的土壤岩芯。土壤岩芯采自6个实验样地（含3个重复区块）；样品以10厘米为间隔，从0至90厘米深度分层采集。本数据包包含.csv格式与.xlsx格式文件各一份，可通过MS Excel或R语言进行读取与处理。本次提供的已预处理数据文件包含苯多羧酸、木质素与水解脂质的浓度信息。本研究的检测目标为评估持续4.5年的全土增温4℃，会对不同土壤深度的结构复杂聚合类化合物产生何种影响。本研究得到瑞士国家科学基金会（Swiss National Science Foundation, SNF）项目172744（DEEP C）以及美国能源部科学办公室生物与环境研究局（合同号DE-AC02-05CH11231）的资助。
