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关注北部高纬度地区与气候变暖相关的关键景观变化，这些变化有可能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旨在加深对以下方面的理解：1）热喀斯特膨胀率和永久冻土-火灾相互作用； 2）解冻后永久冻土碳和氮的命运； 3）解冻敏感地形和碳释放的区域模式。使用经验和建模方法，我们对高纬度生态变化的理解以及我们预测和适应性管理气候变化对永久冻土影响的能力将取得新的进展。
