Arctic Ocean Foraminifera abundance and its relationship to equatorial Pacific Ocean solution cycles

Times of peak Foraminifera abundance in upper Pleistocene Arctic Ocean sediment closely follow the times of glacial interval terminations noted in sediment from equatorial Pacific Ocean. The Arctic Ocean peaks result from interglacial warming and increased penetration of light into the water beneath the Arctic ice pack. Close correlation of Arctic Foraminifera peaks with warm cycles noted on the Ericson and Wollin paleoclimate curve demonstrates a close relationship between North Atlantic and Arctic Ocean environments for at least the past 210,000 yr.
