Abstract
The possibilities and limitations of the induction sounding (TEM method) in the permafrost zone for solving hydrogeological problems are described. On the one hand the fresh water promising layer must have increased electrical resistivity (sand layer in the clay section). On the other hand, it should be a talik zone and should have a lower electrical resistivity in comparison with the surrounding frozen rocks. In the context of such ambiguity, it is important to use additional independent information to take informed decisions in the data interpretation. Such information capabilities are provided by fast-decaying induced polarization associated only with the frozen state of rocks. A number of examples show the effectiveness of the TEM method taking into account fast-decaying induced polarization for complex geocryological conditions of the polar part of Western Siberia.
