Timing of MIS 5e marine optimum and implications for the stratigraphic context of last interglacial sediments in the (sub)arctic North Atlantic
Marine sediment records of dinoflagellate cyst, foraminiferal and ice rafted debris content and stable isotopes from the Nordic seas and Labrador Sea were used to reconstruct the evolution of the surface circulation in the (sub)arctic North Atlantic during the Last Interglacial. Average global tempe...
