Eight Mile Lake Research Watershed, Carbon in Permafrost Experimental Heating Research (CiPEHR): GPS Elevation, 2009-2023

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 dataset contains elevation measurements made using a differential GPS with real time kinematic correction in early August of each year and additionally in mid-May of 2019.

多年冻土碳实验加热研究（CiPEHR）项目旨在解决以下问题：1）生态系统变暖是否会导致碳从生态系统向大气净释放？2）构成土壤碳库主体的古老碳分解是否会影响生态系统碳损失？3）冬季和夏季单独变暖以及组合变暖如何影响生态系统碳交换？我们通过结合野外和实验室实验来回答这些问题，在位于阿拉斯加山脉山麓、阿拉斯加州希利附近的高地苔原野外站点开展的变暖实验中，测量生态系统碳平衡和放射性碳同位素比值。本数据集包含每年8月初以及2019年5月中旬使用实时动态校正的差分GPS（differential GPS）进行的高程测量数据。
