Abstract

The deepness of soil-permafrost layer was measured bу vertical electrical resistivity sounding. It has been revealed that the deepness of active layer оn the Point Thomas oasis , King George lsland is in average about 100-150 cm, while оn the Argentine lslands it is 40-50 cm, which is caused bу climatic conditions. Weak soils of the Argentine Islands are connected to permafrost via the massive rock, while in case of Point Thomas oasis (King-George Island) fine-coarsy gravel soils are underlayed directly bу permafrost.
