The Canadian Permafrost Electrical Resistivity Survey (CPERS) database: 15 years of permafrost resistivity data

Teddi Herring, Antoni G. Lewkowicz, Alexandre Chiasson, Yifeng Wang et autres

Permafrost landscapes are becoming increasingly susceptible to widespread thaw due to climate change. Collating historical and ongoing data are critical for assessing permafrost conditions and spatiotemporal changes. Electrical resistivity tomography (ERT) is a geophysical technique that has become standard practice for characterizing …

Landform mapping, elevation modelling, and thaw subsidence estimation for permafrost terrain using a consumer-grade remotely-piloted aircraft

Greg A. Oldenborger, O Bellehumeur-Génier, A -M LeBlanc, Isabelle McMartin

We assess performance of a small consumer-grade remotely-piloted aircraft (RPA) for landform mapping, elevation modelling, and thaw subsidence estimation in continuous permafrost terrain. We acquired RPA imagery near Rankin Inlet, Nunavut, to construct orthomosaics and digital elevation models (DEMs) that we use …

Permafrost Patch Size Near the Margins of Discontinuous Permafrost, Southern Yukon and Northern B.C.

O Bellehumeur-Génier

This research focused on measuring permafrost patch size and related variables between Fort St. John, BC and Whitehorse, YT. Methods used included electrical resistivity tomography, climate monitoring, active layer measurement, analysis of historical aerial photos, and on-site near-vertical aerial imaging. Where permafrost …

Seasonal surface displacement derived from DInSAR, Rankin Inlet, Nunavut

N Short, A -M LeBlanc, O Bellehumeur-Génier

This map shows the relative ground surface displacement between the major terrain units during one summer in the area of Rankin Inlet. The ground displacement was derived using differential interferometric synthetic aperture radar (DInSAR) data for the summer of 2015. DInSAR data …
