This project will examine the processes for transfer of heat from the atmosphere into the permafrost at the Barrow Environmental Observatory on the North Slope of Alaska. Data loggers will be installed at 3 m depth in the soil at numerous sites to monitor the effects moisture on heat transfer during the seasonal freeze/thaw cycle of the upper permafrost layer. The data will be used to establish how moisture and climate affect the permafrost so that the potential effects of climate change on the permafrost layer may be predicted. The research will test a new theory about the way permafrost responds to seasonal temperature changes in order to examine the role that global warming may play on the surficial frozen soil layer in the arctic. The results are critically important to planning for the potential impacts of proposed climate change on the construction of buildings, roads, and other infrastructure in the arctic.

该项目将在阿拉斯加北坡的巴罗环境观测站研究从大气到永久冻土的热量传递过程。 数据记录器将安装在许多地点土壤中3米深的地方，以监测上部永久冻土层季节性冻融循环期间水分对热传递的影响。 这些数据将用于确定湿度和气候如何影响永久冻土，以便预测气候变化对永久冻土层的潜在影响。 这项研究将测试一种关于永久冻土层对季节性温度变化的反应方式的新理论，以研究全球变暖可能对北极表层冻土层产生的作用。 这些结果对于规划拟议的气候变化对北极建筑、道路和其他基础设施建设的潜在影响至关重要。
