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.

辛辛那提肯尼斯大学的OPP-9732051欣克尔项目将收集、组织并向广泛的研究界提供一组关于整个北极永久冻土带季节性活动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，该项目旨在解决全球变化对北极陆地-大气-冰相互作用(LAII)的影响。北极圈融化层的动态在一定程度上是气温的函数，因此，随着大气二氧化碳增加导致气温上升，它可能是全球变化的先兆。完整的北极圈数据集将提供解决小规模异常和区域变异性所需的广泛覆盖面，如果单独研究这些异常和区域变异性，将由于区域气候趋势而对融化深度的时间趋势产生错误的解释。该项目的结果将与LAII其他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。
