Measurements and experiments on Geomorphic processes in Antarctic ice-free mountains: A review

Abstract

This paper aims to review dynamic approaches to geomorphic processes in the Antarctic ice-free areas, most of which lie in the cold desert zone, and to propose for future research. A variety of methodologies have been used to measure rock weathering, wind erosion, frost heave, slope processes and patterned ground formation. Whereas a number of attempts have been made to quantify rates of erosion or mass movements, difficulties in long-term, continuous monitoring have long militated against understanding of the physical processes that control the rates. Recent progress in automated data logging techniques enables us to acquire data on the timing and cause of geomorphic changes. These data, combined with cosmogenic exposure ages, can be applied to the reconstruction of Late Cenozoic landscape evolution. Experimental techniques should be standardized to promote intersite comparisons of morphogenetic environments.
