Over the past two decades, my students and I have examined the role of groundwater in permafrost terrain, from biomineralization and methanogenesis to ground-ice and river icings. We have demonstrated the importance of water movement through permafrost and its role in catchment hydrology, salmon spawning, ecosystem functioning and water resources. The documented increase in permafrost temperatures potentially enhances the expansion of talik and contribution of groundwater to permafrost hydrology. There are significant implications of enhanced groundwater movement, ranging from heat flux and permafrost stability to solute transport and contaminant migration.

在过去的二十年里，我和我的学生研究了地下水在永久冻土地区的作用，从生物矿化和产甲烷作用到地冰和河流结冰。我们已经证明了水通过永久冻土运动的重要性及其在流域水文、鲑鱼产卵、生态系统功能和水资源中的作用。记录在案的永久冻土温度的增加可能会增强塔利克的扩张以及地下水对永久冻土水文的贡献。地下水运动增强具有重大影响，从热通量和永久冻土稳定性到溶质迁移和污染物迁移。
