Electrical and electromagnetic data for permafrost characterization at Iqaluit International Airport, Nunavut / [by] G.A. Oldenborger, A.-M. LeBlanc and W.E. Sladen. : M183-2/7750E-PDF
Iqaluit International Airport presently suffers from instabilities and subsidence along its runway, taxiways and apron. These instabilities may be related to permafrost, permafrost degradation and associated drainage conditions. In particular, asphalt surfaces are significantly impacted by permafrost degradation, thaw settlement and frost cracking. As part of the Climate Change Geoscience Program, several types of geophysical data have been collected over and around airport infrastructure to characterize permafrost conditions and to investigate active permafrost processes. The geophysical surveys reveal anomalies related to multi-season displacement and groundwater influence.
