The proposed research program will focus on key climate warming-related landscape changes at northern high latitudes that have the potential to alter ecosystem structure, function, and feedbacks to climate. Three areas of proposed research are improved understanding of: 1) thermokarst expansion rates and permafrost-fire interactions; 2) fate of permafrost carbon and nitrogen following thaw; and 3) regional patterns of thaw sensitive terrain and carbon release. Using empirical and modeling approaches, novel advances will be made in our understanding of high latitude ecological change and in our ability to anticipate and adaptively manage for the impacts of climate change on permafrost.

拟议的研究计划将重点放在与气候变暖有关的北部高纬度地区的关键景观变化上，这些变化可能会改变生态系统的结构、功能和对气候的反馈。拟议研究的三个领域是提高对以下方面的理解：1)热岩溶膨胀率和冻土-火相互作用；2)融化后永久冻土碳和氮的去向；3)融化敏感地形和碳释放的区域模式。利用经验和模型方法，我们将在理解高纬度生态变化以及预测和适应气候变化对永久冻土的影响的能力方面取得新的进展。
