Description
Northern and southern hemispheric influences - particularly changes in Southern Hemisphere westerly winds (SSW) and Southern Ocean ventilation - triggered the stepwise atmospheric CO2 increase that accompanied the last deglaciation. One approach for gaining potential insights into past changes in SWW/CO2 upwelling is to reconstruct the positions of the northern oceanic fronts associated with the Antarctic Circumpolar Current. Using two deep-sea cores located ~600 km apart off the southern coast...[Show more]
