The impact of warming on ecosystem carbon balance: aboveground plant biomass from the Carbon in Permafrost Experimental Heating Research (CiPEHR) project, 2009-2013

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 aboveground plant biomass from winter warming, summer warming, and control treatment plots at CiPEHR.

永久冻土碳实验加热研究（Carbon in Permafrost Experimental Heating Research，CiPEHR）项目旨在解答以下科学问题：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旧碳的分解过程是否会对生态系统碳流失产生影响？3）单独或联合开展的冬季与夏季升温，将如何影响生态系统碳交换？本研究依托阿拉斯加山脉山麓、阿拉斯加州希利镇附近的高地苔原野外升温实验站点，结合野外实地实验与实验室分析手段，测定生态系统碳平衡与放射性碳同位素比值，以此解答上述科学问题。本数据集包含CiPEHR项目中冬季升温、夏季升温及对照处理样地的地上植物生物量数据。
