Description:
Taking into account the global warming, there is a pressing need to detect thermokarsts and to monitor permafrosts during the design and construction of industry infrastructure in Northern regions. The paper suggests a permafrost probing method based on the Earth’s natural pulsed electromagnetic field parameters recording. Authors describe the architecture and algorithms for the recording hardware. Examples of thermokarst detecting in poleward region are demonstrated. Pulsed electromagnetic fields intensity over thermokarst funnels is 30 times higher than the background levels. Authors substantiate the method’s eligibility to monitor geocryologial processes.
