THEORETICAL-AND-EXPERIMENTAL ESTIMATES OF AMPLITUDE ATTENUATION IN THE HIGH-FREQUENCY VERTICAL MAGNETIC DIPOLE FIELD COMPONENTS IN FROZEN GROUND OF PERMAFROST ZONE IN YAKUTIA
The description covers the induction sounding-based method to study attenuation of the high-frequency vertical magnetic dipole field in the layer of annual heat circulation in permafrost zone in Yakutia. In terms of the Lena-Amga interstream area in the Central Yakutia lowlands, the theoretical and experimental values of the amplitude attenuation in the vertical and horizontal components of the magnetic dipole field are compared and analyzed. The theoretical and experimental results show satisfactory precision within a wide range of the effective electrical resistance of frozen dispersed ground. The equations for mathematical modeling based on theoretical data on field attenuation in the layer of annual heat circulation are proposed.
