- Аннотация: The paper presents results of GPR investigations on the territory of Russia’s European North carried out in the areas of different lithologies and permafrost conditions in the upper part of the geological section. The GPR surveys were part of the integrated geological and geophysical studies that also included seismic surveying, lithological differentiation of nearsurface deposits, measurement of active layer thickness, and weight rock moisture determination. The GPR was the most effective for the study of sandy and sand-peat geological sections, whereas in loamy environments its efficiency was low. Providing the upper limit of permafrost occurs at shallow depths (less than 1.5 m), which allows direct measurements, GPR can be used as supplementary method for more detailed description of spatial variability of the active layer thickness and other properties, including volumetric moisture estimates calculated from velocities of electromagnetic waves. Alternatively, with the permafrost table occurring deeper than 1.5 m, the GPR proves to be the main method for determining its position in the section. For more accurate geological and geocryological identification of the boundaries, the GPR data interpretation ought to be constrained by seismic results. Application of the GPR in combination with geocryological and seismic methods is ascertained to be highly perspective for solving various engineering problems, which will contribute to the existing permafrost monitoring frameworks.
