All information received in relation to accommodation will be kept confidential. Assessment accommodation **Duties**: In continuous permafrost environments, permanently unfrozen ground beneath large lakes or deep lakes (sublacustrine open taliks) can provide pathways for hydrological interactions between the surface and subsurface. Mining operations in the vicinity of these unfrozen soils entail significant complications (e.g. management of hypersaline groundwater flows). Lack of knowledge on coupled groundwater flow with heat flux and mass transport (deep brines) in these systems exacerbates water management problems in the north. This research aims to improve knowledge of permafrost-groundwater systems in underground mining contexts, ultimately by modelling the effects of underground operations on cryo-hydrogeological processes. The proposed research builds upon our GEM-GeoNorth-funded project (2022-2025) entitled “Talik mapping and conceptual models of subpermafrost groundwater-surface connectivity to inform decisions about mine development facilities”. This project developed a cryo-hydrogeological conceptual model of the study area in a pre-mining context. In the proposed project, the first objective will focus on 2D cryo-hydrogeological numerical simulations (in cross-section) to evaluate 1) coupled processes of flow, heat and mass transport (brines) in sublacustrine open taliks, including processes associated with the presence of permafrost, and 2) the effects of fractured rock and faults on groundwater flow. The second objective will be to simulate the same processes in 3D under the influence of underground mining operations and/or climate change. The modelling will include all processes relevant to the Meliadine mine, including: coupled groundwater flow with variable density, mass and heat transport with freeze/thaw, as well as the effects of lowering water levels due to underground mining operations. **Work environment**: At Natural Resources Canada, a Federal government job means developing leadership skills, fostering teamwork, and supporting creativity and innovation. We know it takes people from diverse pools of talent to make this happen. That is why we are looking for people like you. As an employee at Natural Resources Canada you can enjoy diverse employment opportunities, a range of career development programs, and a learning culture that supports you to learn on an ongoing basis. We support balancing your work and private life by offering the benefits of flexible work arrangements. **Intent of the process**: The intention is to staff a Master student position in Earth Sciences on cryo-hydrogeological modelling of the talik system at the Meliadine mine, Nunavut. **Positions to be filled**: 1 **Information you must provide**: Your résumé. A covering letter "A covering letter indicating the areas of research in which you have knowledge and/or experience." Contact information for 2 references. **The following will be applied / assessed at a later date (essential for the job)**: English or French Information on language requirements Essential Education: Degree equivalency Experience: - Experience in hydrogeology and numerical modelling*. - Experience relevant to the acquisition, organization and analysis of geological data in a Geographic Information System (GIS) and 3D modelling environment. - For the recruitment of students in the federal public service, experienc
