A Novel Lightweight Electromagnetic Induction Sensor for Permafrost Detection and Mapping (opens in new tab)

This article introduces a novel, lightweight, electronically bucked, high-frequency electromagnetic induction (EMI) system for the detection and mapping of spatial freeze and thaw patterns in the near surface of remote, Arctic, and sub-Arctic regions. The system incorporates an electronically isolated transmitter (TX) and bucking coil and utilizes an electronically controlled cancellation approach to suppress the primary magnetic field at the receiver (RX) coil. This integrated hardware–softw...
