Description
For communities that have lived on continuous permafrost for multiple generations, changes to the winter waterscape is a novel experience. Local expert knowledge, ways of knowing, and assessment of cryohydrogeologic-based hazards have developed based on a regime of limited lateral groundwater movement during winter. Yet, there is growing evidence of changing winter groundwater dynamics along Inuit overland travel routes in the continuous-permafrost region of Nunavut, Canada. The research objective is to combine Inuit Qaujimajatuqangit (knowledge and ways of knowing) with groundwater and permafrost science to identify and assess local community-relevant landscape indicators of winter groundwater movement. Winter overland travel primarily consists of snowmobiling and dog sledding, and encountering groundwater springs is a winter overland travel hazard. Utilizing both local community member knowledge and satellite imagery, we document and categorize past and present groundwater spring locations in Nunavut. We then analyze groundwater chemistry, temperature, flow rate, and lithology of the springs. Combined, these results provide an understanding of Nunavut perennial groundwater spring characteristics, and enhance predictions of future perennial groundwater spring occurrence in response to climate change. Currently, models of Arctic climate, environmental, and societal change generally do not account for near-surface groundwater processes nor its effects on local community-relevant cryohydrogeologic dynamics. Our research study was co-designed with Inuit and local-community governments and organizations in Nunavut. By following an inclusive research model, the study results are of a scale, format, and timeframe relevant for Inuit and local community resilience planning.
