Summary: This paper summarizes the principal scientific results from Legs 119 and 120 of the Ocean Drilling Program as they relate to the Cenozoic glacial and climatic history of Antarctica. These two legs cored 16 sites on a south-north transect from the Antarctic continental shelf of Prydz Bay to the north Kerguelen Plateau. Glacigenic sediments were recovered in Prydz Bay. The Kerguelen Plateau yielded pelagic and glaciomarine sediments. Clay sediments and ice-rafted debris and oxygen isotope composition of foraminifera are integrated. Long-term cooling is indicated from 52 Ma with several major advance and retreat phases. Major increases of ice occurred in both the middle Miocene and late Miocene with the latter associated with the growth of the West Antarctic ice sheet. (SNT)
