| Abstract | (unpublished)
The new Grays Bay - Yellowknife corridor will provide transportation, energy, and telecommunications to northcentral Canada, and connect existing highway infrastructure to a
deep-sea port on the Arctic Ocean. This infrastructure will improve access for exploration and development, and reduce operating costs in this mineral-rich region of the Northwest Territories and Nunavut, one of the biggest impediments to development
in this region. Relatively little information on permafrost and ground ice conditions is available for most of the corridor. To fill this information gap, the Geological Survey of Canada's GEM-GeoNorth program is compiling permafrost and surficial
geology information, mapping periglacial terrain features, and modelling ground ice conditions along the corridor. This poster presents the periglacial feature mapping component. Periglacial features are landforms associated with cold environments
and typically contain permafrost. Permafrost, and its related ground ice, affect terrain sensitivity to climate change and surface disturbance. With development of this periglacial terrain and accelerated climate warming in the north, communities,
planners, and regulators require this information to make informed decisions on how and where to build and manage environmentally sustainable and climate change-resilient infrastructure, and determine best adaptation strategies. |
| Summary | (Plain Language Summary, not published)
The new Grays Bay-Yellowknife corridor will provide transportation, energy, and telecommunications to northcentral Canada, and connect existing highway
infrastructure to a deep-sea port on the Arctic Ocean. Permafrost and ground ice conditions can create potential geohazards for infrastructure development, but relatively little information on is available for most of the corridor. To fill this
information gap, the Geological Survey of Canada's GEM-GeoNorth program is compiling permafrost and surficial geology information, mapping periglacial terrain features, and modelling ground ice conditions along the corridor. This poster presents the
preliminary periglacial feature mapping results. |
