PhD Thesis: Changes in AMOC over Holocene and previous interglacials- Mg/Ca temperature reconstructions of mixed layer and NADW in the subpolar and subtropical North Atlantik
The heat transport to the northern high latitudes is governed by the intensity of the Atlantic Meridonal Overturning circulation (AMOC). Within the frame of the ESF-EUROMARC Project AMOCINT1 my thesis aims to reconstruct AMOC strength in the subpolar and subtropical North Atlantic during Holocene and previous interglacials. These records will help to improve our knowledge of climate variability beyond the reach of human influence and under differential external forcing scenarios. Centennial to millennial scale variability of AMOC is explored at its upper and lower limbs. Changes in North Atlantic deep water (NADW) production are traced downstream from the overflow regions into the deep subtropical East Atlantic ridge basin (using deepwater temperatures and salinity (combined Mg/Ca and 18O analyses), and ventilation (13C)). Changes in surface hydrography in the North Atlantic drift and Azores current are reconstructed (seasurface temperature, salinity, and mixed layer depth by combined planktic Mg/Ca and 18O analyses)
