Eight Mile Lake Research Watershed, Carbon in Permafrost Experimental Heating Research (CiPEHR): Aboveground plant biomass, 2009-2017. (Reformatted to the ecocomDP Design Pattern)

This data package is formatted as an ecocomDP (Ecological Community
Data Pattern). For more information on ecocomDP see
https://github.com/EDIorg/ecocomDP. This Level 1 data package was
derived from the Level 0 data package found here: https://pasta.lternet.edu/package/metadata/eml/knb-lter-bnz/501/17. The
abstract below was extracted from the Level 0 data package and is
included for context: 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.

本数据集包采用ecocomDP（Ecological Community Data Pattern，生态群落数据模式）格式构建。如需了解ecocomDP的详细规范，请访问：https://github.com/EDIorg/ecocomDP。本一级（Level 1）数据集包源自此处提供的零级（Level 0）数据集包：https://pasta.lternet.edu/package/metadata/eml/knb-lter-bnz/501/17。下述摘要提取自该零级数据集包，用于提供背景信息：永久冻土碳实验加热研究（Carbon in Permafrost Experimental Heating Research，简称CiPEHR）项目旨在解答以下三个科学问题：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，是否会对生态系统碳流失产生影响？3. 单独施加冬、夏季升温处理，以及二者联合施加，会如何影响生态系统碳交换过程？本研究结合野外实地与室内实验室实验，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升温实验样地中，测定生态系统碳平衡与放射性碳同位素比值，以此回应上述科学问题。本数据集涵盖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。
