Lithostratigraphic correlation of core PS92/039 (left) and core PS92/045 (right) which forms the basis of the age model used here47,48. Correlation between environmental magnetic parameter kARM/k (ratio between the anhysteretic magnetic susceptibility and the bulk magnetic susceptibility) variations of the two Yermak Plateau cores and the global benthic δ18O curve of Lisiecki and Raymo94 is shown by brown lines. Brown dots shows the two depths at which radiocarbon dates were measured in core PS92/045.
