**Duties**:
In the continuous permafrost zones at high northern latitudes in Canada, layers of permanently thawed ground, known as taliks, are present beneath lakes and rivers. If there is sufficient groundwater in these taliks, these aquifers can be tapped to supply drinking water to northern communities. For instance, groundwater from a fractured aquifer in the talik beneath the Kuguuluk River in Salluit, an Inuit community in Nunavik (Quebec), is used as a source of drinking water. However, uncertainties remain about the aquifer potential of this talik, the availability and quality of the groundwater, the vulnerability of this river-talik system to the impacts of climate change, and the sustainability of this talik as a source of drinking water. As part of the Geological Survey of Canada’s (GSC) GEM-GeoNorth program, the talik beneath the Kuuguluk River will be studied in detail to address the above uncertainties by delineating it with geophysical surveys, instrumenting it to monitor ground temperature and hydraulic head in the aquifer, installing wells to sample and measure groundwater quality, and carrying out numerical modelling of groundwater flow and heat transfer to assess the impact of global warming on the talik dynamics. The results of this study will be useful for other northern communities in continuous permafrost environments who wish to exploit the talik aquifers for sustainable access to drinking water of sufficient quality and quantity.

As part of the study of this river-talik system in Salluit, a M.Sc. research project is proposed to carry out a cryohydrogeophysical investigation of the talik beneath the Kuuguluk River. The main objectives of this research project are 1) to delineate the talik limits and adjacent permafrost conditions using various geophysical surveys, and 2) to improve a conceptual 3D cryohydrogeological model of the Salluit valley based on new constraints derived from mapping of Quaternary deposits, drilling and geophysical investigations. 2D and 3D ground-penetrating-radar profiles, as well as 2D and 3D electrical resistivity tomography using galvanic contact with the ground surface and capacitive coupling, will be carried out during the geophysical investigations.

This M.Sc. research project in cryohydrogeophysics is part of the study of the talik under the Kuuguluk River in Salluit. A Ph.D. research project and two other M.Sc. research projects are included in this study. As part of the PhD research project, the 3D cryohydrogeological conceptual model will be used to simulate groundwater flow and heat transfer by conduction and advection in the talik and adjacent permafrost for understanding the dynamics of cryohydrogeological processes taking place in the river-talik system in Salluit and assessing groundwater availability. The two other M.Sc.research projects will focus on groundwater geochemistry and quality, and organic matter remobilization and microbial activity. A team of experts from the GSC, the Institut national de la recherche scientifique (INRS) and Centre d'études nordiques (CEN) at Université Laval will oversee these research projects. The person selected for this M.Sc. research project in cryohydrogeophysics will be actively involved in geophysical investigations of the talik beneath the Kuuguluk River in Salluit, processi
