Abstract
Ice thickness measurements carried out by field parties based on Mawson during 1957-59 consisted of: (:) regional traverses in the form of closed loops extending several hundred kilometres inland from Mawson; (ii) semi-detailed traverses in the vicinity of a line of ice flow stakes about 25 Km from Mawson. The regional traverses showed that, beyond about 175 Km inland, the area surveyed is influenced strongly by the Lambert Glacier - Amery Ice Shelf system situated some 200 Km to the East. Preliminary contour plans of the ice and rock surfaces show fairly close correspondence. A sub-glacial extension of a range of mountains outcropping through the ice 80 Km to the East of the traverses was found. Work along the semi-detailed traverses close to Mawson detected sub-glacial extensions of the outcropping mountain ranges in the area. These extensions may explain the general direction of the coastline near Maws on.

Lineage
During the period of the International Geophysical Year, 1957-58, the Australian National Antarctic Research Expeditions (A.N.A.R.E.) carried out a programme of ice thickness measurements on the Antarctic ice cap. Field parties for this work were based at Mawson station. One geophysicist of the Commonwealth Bureau of Mineral Resources was attached to A.N.A.R.E. during each of the two years covered by the I.G.Y. for the purpose of making these and other measurements. The regional traverse 1958 -1959 is the second traverse, which was to preceed as rapidly as possible to the depot established during the first survey and from there to run traverses in the form of loops approximately 160 km squre to the East and West.
