Sequencing Ocean-Ice-Climate Interaction in the North East Atlantic

PROJECT DETAILS ONLY - NO DATA. Abrupt shifts in North Atlantic palaeoceanographic and ice-rafted detrital (IRD) records indicate a strong link between the meridional heat flux driven by thermohaline circulation (THC) and glacimarine discharges from the Late Pleistocene ice sheets. We propose a detailed multiple proxy investigation into ocean-ice-climate interaction in the NE Atlantic to: (i) reconstruct the variability of THC (surface and deep circulation); (ii) establish the source and timing of IRD events (geochemical and petrographic fingerprinting); (iii) generate a high-resolution chronostratigraphic framework that will allow us to (iv) sequence the interaction between North Atlantic THC, climate and ice sheet behaviour associated with Heinrich events, their precursors and D-O oscillations at centennial to interdecadal timescales.
