Individual lithofacies can be correlated across hundreds of kilometres. Two ash horizons provide useful stratigraphic markers. Peaks in foraminiferal abundance indicate that two main penetrations of subarctic water occurred in Baffin Bay during the past 100,000 yr. One penetration occurred about 70,000 to 40,000 yr B.P. and another at 9,000 to 6,000 yr B.P. Both were accompanied by distribution of ice-rafted carbonate sediment over a wide area of Baffin Bay and the eastern Canadian continental margin.
