Vertical electric resistivity sounding of natural and anthropogenically affected cryosols of Fildes Peninsula, Western Antarctica
Natural and anthropogenically-affected Cryosols of the Fildes Peninsula (King George Island, NWAntarcticPeninsula) from the surroundings of Russian polar station Bellingshausen were investigated by vertical electric sounding. The aim of the study was to asses the thawing depth and active layer thick...
