Response of the Global Active Layer-Permafrost System to Climate: CALM - The Circumpolar Active Layer Monitoring Program

摘要 辛辛那提肯内特大学HINKEL 该项目将收集、组织并向广大研究界提供一套关于整个北极地区永久冻土区季节性活跃融化层厚度的国际数据。 该项目是一个多学科项目的一部分，该项目涉及全球变化对北极陆地-大气-冰相互作用的影响。 环北极解冻层的动态部分是空气温度的函数，因此，可以作为全球变化的预兆，因为温度上升，以应对大气中二氧化碳的增加。 完整的环北极数据集将提供解决小规模异常和区域变化所需的广泛覆盖范围，如果单独研究，将产生不正确的解释，由于区域气候趋势的解冻深度的时间趋势。 该项目的结果将与其他LAII项目的结果结合使用，以确定全球变化对整个北极陆地系统的区域影响。

ABSTRACT OPP-9732051 HINKEL, KENNETH UNIVERSITY OF CINCINNATI The project will gather, organize, and make available to a wide research community an international set of data on the thickness of the seasonal active thaw layer of the permafrost zone throughout the Arctic. The project is part of a multidisciplinary project that addresses the impact of global change on land-atmosphere-ice interactions (LAII) in the Arctic. The dynamics of the circumarctic thaw layer is partly a function of the air temperature and, therefore, may serve as a harbinger of global change as temperatures rise in response to increased atmospheric carbon dioxide. The full circumarctic dataset will provide the wide coverage necessary to resolve small-scale anomalies and regional variability that, if studied alone, would yield incorrect interpretations of temporal trends in thaw depth due to regional climatic trends. The results of this project will be used in combination with those of other LAII projects to determine the regional impacts of global change on terrestrial systems throughout the Arctic.
