Eight Mile Lake Research Watershed, Carbon in Permafrost Experimental Heating Research (CiPEHR): CiPEHR snow depth manual data 2009-2025

The Carbon in Permafrost Experimental Heating Research (CiPEHR) project addresses the following questions: 1) Does ecosystem warming cause a net release of C from the ecosystem to the atmosphere?, 2) Does the decomposition of old C, that comprises the bulk of the soil C pool, influence ecosystem C loss?, and 3) How do winter and summer warming alone, and in combination, affect ecosystem C exchange? We are answering these questions using a combination of field and laboratory experiments to measure ecosystem carbon balance and radiocarbon isotope ratios at a warming experiment located in an upland tundra field site near Healy, Alaska in the foothills of the Alaska Range. This data set includes manual measurements of snow depth collected in early spring on winter warming and control treatment plots.多年冻土碳原位加热研究（Carbon in Permafrost Experimental Heating Research, CiPEHR）项目旨在解答以下三项科学问题：1）生态系统升温是否会引发碳从生态系统向大气的净释放？2）占土壤碳库主体的老碳分解过程是否会影响生态系统碳流失？3）单独或联合施加冬季与夏季升温措施，将如何作用于生态系统碳交换？本项目通过野外实验与实验室实验相结合的手段，在位于阿拉斯加山脉山麓、阿拉斯加州希利镇附近的高地苔原野外加热实验场地中，测量生态系统碳平衡与放射性碳同位素比值，以解答上述科学问题。本数据集包含早春时节在冬季加热处理样地与对照处理样地中采集的雪深手动观测数据。
