SPRUCE Deep Peat Heating (DPH) Environmental Data, February 2014 through July 2015

This data set provides a record of the half-hourly automated environmental data collected for 14 SPRUCE plots (4, 5, 6, 7, 8, 10, 11, 13, 14, 16, 17, 19, 20, and 21) during the Deep Peat Heating (DPH) study. In June 2014, deep soil heating was initiated at 5 warming levels (+0, +2.25, +4.5, +6.75 and +9 °C) with 2 replicate plots per level. Measurements were underway before the initiation of heating treatments and continued through July 27 of 2015 at the transition to whole-ecosystem warming manipulations. The DPH study was undertaken to evaluate possible rapid responses of deep peat carbon (C) stocks, microbial communities, and biogeochemical cycling processes to unprecedented temperatures. Warming levels at depth were achieved over a 25 (+ 2.25 °C) to 60-day (+9 °C) period depending on the target treatment temperatures.本数据集收录了深泥炭加热（Deep Peat Heating，DPH）研究期间，14个SPRUCE样地（编号依次为4、5、6、7、8、10、11、13、14、16、17、19、20、21）的半小时自动化环境监测记录。2014年6月，该研究启动了5级深层土壤增温处理，增温梯度分别为+0、+2.25、+4.5、+6.75与+9 °C，每个梯度设置2个重复样地。监测工作于增温处理启动前即已开展，并持续至2015年7月27日，此后该站点转向全生态系统增温操控实验。DPH研究的核心目标为评估深层泥炭碳（C）库、微生物群落及生物地球化学循环过程对前所未有的升温幅度的潜在快速响应。根据目标增温温度的不同，深层土壤达到预设增温水平所需时长从25天（对应+2.25 °C）至60天（对应+9 °C）不等。
