Abstract:
Here we establish a spatio-temporal evolution of the sea-surface temperature anomalies in the North Atlantic over Dansgaard Oeschger (DO) events 5-8 (30-40ka) using the proxy surrogate reconstruction method. We combine fully coupled, general circulation model simulations with planktic foraminifera based sea-surface temperature reconstructions to obtain a broader spatial picture of the ocean state during DO-events 5-8. Here, the model simulations consists of 10 simulations with HadCM3, 8 runs without freshwater forcing and 2 runs with freshwater forcing. These simulations were run by Paul J. Valdes, Joy S. Singarayer and William H.G. Roberts. A description of the simulations can be found in Singarayer and Valdes (2010). All model simulations were run using the University of Bristol's ACRC facilities, (www.acrc.bris.ac.uk). This is the first time the proxy surrogate reconstruction method has been applied to oceanic variability during MIS3. The sea-surface temperature reconstructions should be used with care.
