AbstractThis paper examines environmental conditions and landscape hazards in the hamlet of Kugluktuk, Nunavut, based on observations made during a reconnaissance field survey in summer 2009, and an analysis of stereo airphotos. Conditions as they relate to permafrost, terrain and coastal stability and their potential impacts on infrastructure are assessed based on the present-day, and also how future climate change may positively or negatively increase perceived risk. This research is designed to assist future community planning activities by identifying the range of potential landscape hazards that currently exist, and indicating which conditions will require detailed analysis, monitoring and integration.
Summary(Plain Language Summary, not published)
This report provides suggestions as to the range of environmental conditions that would require detailed study and investigation in order to best assist the community and the Government of Nunavut in planning, design and development of new and existing infrastructure in Kugluktuk. In Arctic regions, it is important to understand issues that relate to the permafrost that underlies the landscape. Where changes to the landscape, such as digging drainage ditches, expose frozen ground that has a lot of ice in it, significant melt and settling of the land can take place over many years, damaging infrastructure built upon or adjacent to it. Identifying where sediments are thicker, and which types of sediments are more likely to contain buried ice, helps to determine which areas are likely best to expand community development onto, and which areas require special attention and caution. Future changes in climate and weather can also impact what was previously stable terrain.
