Collaborative Research: Spatial and Temporal Variability of Ground Temperature and Thaw, Northern Alaska

该项目将更详细地研究阿拉斯加北方土壤的融化深度。 气候变化增加了融化的深度，侵蚀了永久冻土，对植被、水文平衡和人类结构产生了影响。 这项研究将完善现有的方法，在当地和区域尺度上绘制解冻深度。 浅层热制度将在一系列的空间尺度进行评估，以阐明土壤结构对热传输的作用。 通过人工模拟试验研究了大雪荷载对融化深度的影响。 此外，该项目还将研究阿拉斯加北方社区对热岛效应的影响。

The project will examine in greater detail the depth of thawing of the soils in northern Alaska. Climate change is increasing the depth of thaw and eroding permafrost with concomitant impacts on vegetation, the hydrological balances, and human structures. This research will refine existing methods for mapping the depth of thaw on local and regional scales. The shallow thermal regime will be evaluated across a spectrum of spatial scales in order to elucidate the role of soil structure on heat transport. The impact of heavy snow loading on the thaw depth will be examined based on manipulative experiments. Also, the project will also examine the role of the heat island affect by a community in northern Alaska.
