Summary
Abstract: Geochemical and sedimentological evidence suggest that the rapid climate
warming oscillations of the last ice age, the Dansgaard-Oeschger cycles, were
coupled to fluctuations in North Atlantic meridional overturning circulation
through its regulation of poleward heat flux. The balance between cold
meltwater from the north and warm, salty subtropical gyre waters from the
south influenced the ... View entire text
