Scientists at the Institute of Petroleum Geology and Geophysics. AA Trofimuka (IPGG) from SB RAS has developed for the first time a method for monitoring the state of permafrost. To do this, they use electromagnetic sensors. The new method should yield more accurate results than traditional thermal methods. It also has other advantages: it will make it possible to monitor the dynamics of processes occurring with permafrost. writes about it TASS With reference to the official publication of SB RAS “Science in Siberia”.
The method is based on periodic measurement of pulsed electromagnetic sounding signals. They pass through the rock and vary depending on whether it is frozen or thawed. The sensors are not affected by temperature, but by the electrical resistance of the rocks, which is already temperature dependent.
Field experiments at the geophysical test sites of the Novosibirsk region to test the prototype of the measuring equipment demonstrated the effectiveness of the measuring systems. They gave very good results.
