Elevated Soil Temperature and Water Table Manipulation Data from Barrow, Alaska, 1999-2001

This data set contains elevated soil temperature and water table manipulation measurements taken at a tundra site near Barrow, Alaska, USA. Eighteen 60-cm diameter polycarbonate cylinders were installed into the ground at the end of the 1998 growing season when thaw depth was at its seasonal maximum to isolate plots of tundra. The cylinders were organized into three blocks of six for three replicates of the six treatments to be tested. The six factors tested include: control, elevated water table, lowered water table, elevated soil temperature, elevated soil temperature and elevated water table, and elevated soil temperature and lowered water table. Temperature data were collected from June 1999, until September 2001. Measurements were taken as part of the Land-Atmosphere-Ice Interactions Arctic Transitions in the Land-Atmosphere System (LAII-ATLAS) program. The research project was funded by the Arctic System Sciences (ARCSS) Program, grant number OPP-9732105.

本数据集收录了美国阿拉斯加州巴罗附近苔原站点开展的土壤升温与地下水位调控原位观测数据。1998年生长季末期（彼时土壤解冻深度达到季节峰值），研究人员于地下埋设了18个直径60cm的聚碳酸酯（polycarbonate）圆柱筒，以隔离出独立苔原样地。该圆柱筒被划分为3个组块，每组6个，对应6种待测试处理的3组生物学重复。本次测试的6种处理分别为：对照组、抬高地下水位组、降低地下水位组、土壤升温组、土壤升温+抬高地下水位组，以及土壤升温+降低地下水位组。土壤温度数据的采集时段为1999年6月至2001年9月。本观测隶属于“陆地-大气-冰相互作用北极陆地大气系统转型”（Land-Atmosphere-Ice Interactions Arctic Transitions in the Land-Atmosphere System, LAII-ATLAS）计划。本研究项目由北极系统科学（Arctic System Sciences, ARCSS）计划资助，资助编号为OPP-9732105。
