Abstract

Results of grain size analysis and rock magnetic measurements of core NP95-1 from Prydz Bay, Antarctica revealed two series of ice-rafted detritus layers, which correspond to cold climatic events, Younger Dryas and Heinrich event 1, occurring at about 11.7-10.3 and 14.3-13.6 kaB.P. respectively. Studies also show that the sequence of paleoclimatic changes in Antarctica can be correlated with that in other parts of the world, and that the millennia1 climate of the earth could change synchronously and globally. In addition, magnetic fabric analysis also shows a close relationship between paleoclimatic change and ocean circulation re-assemblage.
