Resistivity mapping of fossil permafrost patterns in southwestern Ontario

Fossil ice-wedge polygons, recognizable from their distinctive patterns on air photographs of certain till sheets in southwestern Ontario, can be mapped at ground level using small scale resistivity profiling. This technique is useful for locating specific polygon boundaries (for coring or trenching...

Description
Summary:Fossil ice-wedge polygons, recognizable from their distinctive patterns on air photographs of certain till sheets in southwestern Ontario, can be mapped at ground level using small scale resistivity profiling. This technique is useful for locating specific polygon boundaries (for coring or trenching) which have been identified from airborne surveys.
