Abstract

During the seasonal works in the 9-th Ukrainian Antarctic Expedition the thickness of the ice cap near the Academic Vernadsky station on the Galindez Island was measured using the vertical electric-resonance sounding method (ERS-method) based on studying the processes of the natural polarization of environment and spectral features of natural electric field under investigation objects. The method permits to define the location depths of the stratigraphic cross-section complexes and separate anomalous objects. Results of these works were used to set up: a) a sketch-map and 3-D diagram of the ice cap thickness on Galindez Island; b) vertical sections of the glacier mass along five profiles; c) sketch-map and 3-D diagrams of the Galindez Island surface both with the ice cap and without it. It was shown that the vertical electric-resonance sounding method can be effectively used for studying the ice cap structures of the West Antarctic region.
