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，我和我的学生们研究了地下水在永久冻土地带的作用，从生物矿化和甲烷生成到地面冰和河流冰。我们已经证明了水在永久冻土中移动的重要性，以及它在集水水文、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上升有可能加强塔利克的扩展和地下水对永久冻土水文学的贡献。从热通量和永久冻土稳定性到溶质迁移和污染物迁移，加强地下水运动具有重大意义。
