(Table 1) Age determination of sediment profile JM96-1225
The paleoceanography in the Denmark Strait, North Atlantic, is reconstructed based on down core analysis of planktonic foraminifera, carbon and oxygen isotopes, carbonate, and ice rafted debris (IRD). The stratigraphy spans 57 to 6 calibrated (cal) ka years and reveals sea surface temperatures that...
