Assessing the impact of rising temperatures on the 30-60m deep continuous permafrost underlying the town of Churchill, Manitoba on the western shoreline of Hudson Bay, between 2006 and 2016. Techniques of remote sensing will be used to monitor indirect indicators such as snow cover, vegetation cover and thermokarst lakes to detect any changes that may have occurred within the local permafrost over the approximate 10-year period. The extent of any changes will be analysed and how these changes affect infrastructure within the region. ERDAS Imagine 2015 will be the primary software used for the remote sensing data processing aspect. The NDVI and NDSI will be calculated for data at intermittent time periods throughout the research period to determine if any significant changes in vegetation or snow cover have occurred within the region. Multi-temporal change detection of thermokarst lakes located within the study area was also completed, using overlay analysis of polygon vector shapefiles.
