A note on the ice sheet fluctuations and problems of Cenozoic studies in Antarctica

This note outlines briefly the present state of research on some aspects of glacial history in Antarctica and attempts to compare chronologically the glacial events in several regions of Antarctica with one another as the basis for future investigations. Investigations on the ice sheet fluctuations...
