AbstractIn partnership with the Canada-Nunavut Geoscience Office, scientists in the Earth Sciences Sector of Natural Resources Canada and their collaborators have carried out activities in several regions of resource industry activity in Nunavut under the Coastal Infrastructure Project of the Earth Sciences Sector's Climate Change Geoscience Program. These activities focused on coastal characterization, coastal instability, sea-level change, coastal hazards and vulnerability in the context of climate change. A mosaic of satellite imagery (SPOT) and interpretation of coastal video of Coronation Gulf and surrounding regions provide baseline coastal characterization. Potential applications include assessment of the accessibility and nature of candidate port sites, and assessment of available aggregate resources. A coastal change study of the community of Kugluktuk reveals that the town-site coastline is largely stable, but there is rapid coastal change near the port site and on islands of the Coppermine delta, as well as localized bank erosion in town. A coastal hazard assessment of Iqaluit, the capital of Nunavut, reveals infrastructure at risk from rising sea levels. In contrast to Iqaluit, a relative sea-level projection for the outlet of Baker Lake indicates that sea level is expected to continue to fall throughout the 21st century because of the large rate of land uplift.
