ABSTRACT. The Wilkes Station area comprises 75 km.' of rock which form one of the most extensive exposures on this part of the East Antarctic coast. During 1957 and 1958 the continental ice sheet south-east of Wilkes Station was explorcd to a distance of 100 km. inland, and its form and behaviour studied by means of topographic, movemen.t and gravity surveys. Surface stake measurements inland showcd a net accumulation equivalent to 13' 7 cm. of water in 1958. Sub-surface measurements of wctness, hardness, density, grain size, crystal size, shape and fabric and electrical conductivity were made at 60 locations and to depths which reached 62 m. at an auxiliary inland station. Meteorological observations were made and englacial temperatures measured. In summary, the ice shect in this area provides a typical section of a polar glacier. The evidence for glacial fluctuations and the possibility of establishing a chronology for these are discussed.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
