Electrical depth soundings in Antarctic dry valleys.
Electrical depth soundings to depths of approx. 150m were made at 26 sites in Wright and Taylor valleys, Antarctica, during Dec. 1969-Jan 1970. It is interred that Lakes Vanda and Bonney are not underlain by permafrost. Electrical depth soundings obtained with electrodes placed in marginal ice streams adjacent to Taylor Lower Glacier indicate that the permafrost zone extends from near the surface to depths great than 150m. Conditions which may have influenced the dry valley geothermal history are discussed.
