Assessment of physicochemical properties in lentic water bodies of the Rankin Inlet area (Nunavut) for sublacustrine open talik detection / B. Faucher, A.-M. LeBlanc, N. Utting, and M. Blade.: M183-2/8898E-PDF
"In periglacial landscapes of Northern Canada, the presence of open taliks (layer of unfrozen ground that penetrates permafrost completely) beneath lakes can connect surface waters to subpermafrost groundwater. With increasing mining activity in northern Canada, it is critical for mining projects to identify lakes potentially underlain by open taliks and their subpermafrost groundwater-surface water connectivity to assess effects on mining operations and lake water levels, lake water quality, and regional groundwater systems. The presence of sublacustrine open taliks can be assessed with thermal models, but validating their presence remains challenging at a regional scale due to the difficulty and cost of acquiring field data at this scale. The level of hydrological connectivity between the lakes and subpermafrost groundwater systems also remains largely unknown. This work explores the physical attributes and water chemistry of lakes in the Rankin Inlet area (NU) to infer the presence of open talik and to quantify connectivity between lakes and groundwater"--Summary, page i.
