Short summary
This work documents major oceanographic changes that occurred in the N. Atlantic from 812 to 530 ka and were related to the mid-Pleistocene transition. Since ~ 650 ka, glacials were more prolonged and intense than before. Larger ice sheets may have worked as a positive feedback mechanism to prolong the duration of glacials. We explore the connection between the change in the N. Atlantic oceanography and the enhanced ice-sheet growth, which contributed to the change of cyclicity in climate.
