Description: 
Geophysical measurements of electrical resistivities and seismic properties of rock, water, and soil in the dry valleys of Antarctica, reveal abnormally thin permafrost with respect to the present climate. This is due to the presence of solar-heated lakes and to high water and soil salinities.
