| Summary | (Plain Language Summary, not published)
Open taliks, areas of unfrozen ground, are mainly found beneath large and deep lakes that do not freeze to their bottom. Open taliks connected to
regional groundwater can affect the development of mine projects by providing pathways for mine water inflow or contaminant transport. This study presents a methodology to assess the presence of taliks below Arctic lakes at a regional scale. The
methodology uses existing information on lakes and their surrounding ground and additional information from high-resolution satellite imagery and a digital elevation model. Results, under the form of regional maps, for mineral resource development
areas in Nunavut are provided. |
