An innovative approach, based on both well-established and newly-developed analytical methods will be applied to characterize, qualitatively and
quantitatively, past changes in the MedTHC dynamics. Specific time windows representing very different transient periods
(18-14 ka BP; 9.5-6.5 ka BP and the last 2 kyr) will be targeted in order to understand the distinctive role that individual
forcing mechanisms exerted in controlling MedTHC changes. Particular emphasis will be placed on building robust regional
chronologies and proxy records with unprecedented high-resolution. This approach will combine proxy data from sediment
cores and deep-sea corals along the main paths of water masses as they cross the Mediterranean basins and exit into the
North Atlantic. This paleo-data analysis will be complemented with novel climate model paleo-simulations to test the
sensitivity of the AMOC to changes in Mediterranean outflow under varying AMOC conditions. The main goals are to identify:
(1) The natural range of MedTHC variability; (2) The forcings and inter-regional teleconnections driving MedTHC changes;
(3) The associated impact onto the AMOC.
