Historical fluctuations of lake shorelines based on geomorphological analysis in the vicinity of Rankin Inlet, Nunavut / O. Bellehumeur-Génier, G.A. Oldenborger, and A-M. LeBlanc.: M183-2/8224E-PDF
“The purpose of this Open File is to provide information derived from the analysis of lake shorelines in the vicinity of Rankin Inlet, Nunavut. The analysis focused on three areas of interest located north of Rankin Inlet, with different surficial material mosaics. A total of 220 lakes were digitized from air photos and satellite imagery using a geographical information system (GIS) for the period 1954 to 2014. Lake surface areas were computed using the digitized polygons. A visual assessment of the geomorphological dynamics of individual lakes was undertaken to differentiate normal shoreline behavior from that potentially associated with thermokarst. Results showed that lakes in the areas of interest have experienced significant shoreline fluctuation as part of normal lake behavior. Despite the high degree of normal shoreline variability, the geomorphological analysis revealed that certain lakes demonstrated abnormal increases or decreases in area, along with localized shoreline dynamics”--Abstract, p. iii.
