Permafrost table depth in soils of Eastern Antarctica oases, King George and Ardley Islands (South Shetland Islands)
This study was aimed to investigate the electrical resistivity in soils and permafrost of various ice-free areas of Antarctica and Sub-Antarctica (from coastal Eastern Antarctica oases to Maritime Antarctica). Measurements of electrical resistivity of soil and permafrost strata were performed with a...
