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.

本数据集记录了深层泥炭加热（Deep Peat Heating，DPH）研究期间，针对编号为4、5、6、7、8、10、11、13、14、16、17、19、20、21的14个SPRUCE样地（SPRUCE plots）采集的半小时级自动化环境监测数据。2014年6月，研究启动了5个升温水平的深层土壤加热处理，各升温水平分别为+0、+2.25、+4.5、+6.75与+9℃，每个升温水平设置2个重复样地。升温处理启动前已开展监测工作，并持续至2015年7月27日，直至转入全生态系统增温操控实验阶段。本DPH研究旨在探究深层泥炭碳（C）库、微生物群落及生物地球化学循环过程对极端升温的潜在快速响应。根据目标处理温度的不同，深层升温的达标时长介于25天（对应+2.25℃升温）至60天（对应+9℃升温）之间。
