| Abstract | Surficial and periglacial-permafrost geology mapping was undertaken in Clyde River, Nunavut, to assess how different aspects of the physical environment pose risks and hazards to existing and future
infrastructure development, and how climate change may further alter infrastructure vulnerability. This research was undertaken as part of Natural Resources Canada's Climate Change Geoscience program and the Nunavut Climate Change Partnership. Most
of Clyde River's town and airport are built atop thick, terraced, raised marine and glaciomarine sandy sediments that contain saline permafrost. These deposits support abundant ice wedges. Widespread thermokarst depressions indicate extensive massive
and segregated ice content. Moraines, meltwater channels and ice-contact deposits record a fiord-ward and westward retreat of Late Wisconsinan glaciers. New community developments extend upslope from the coastal terraced regions on washed sandy till
and moraine complexes. Granular aggregate materials suitable for infrastructure development are rare, although glaciofluvial terrace deposits offer potential. |
