The Neogene opening and subsequent widening of the only deep-water connection between the Atlantic-Arctic Gateway (AAG) had fundamental influence on global ocean circulation, paleoclimate evolution, and on sedimentation processes in adjacent ocean basins and continental margins. To unravel the evolution of the Fram Strait on tectonic time scales we combined seismic reflection data with sedimentological and stratigraphic information from ODP Site 909 (Molloy Basin). We derived a higher resolution seismic stratigraphy that is based on a revised chronology for Site 909 and an improved core-log-seismic integration. A revised interpretation of magnetostratigraphic boundaries, shifts previously used stratigraphies for Site 909 to significantly younger ages in the time interval from c. 15 to 3 Ma and allows a more comprehensive correlation with seismic markers from the western Barents Sea margin and also the adjacent Yermak Plateau.
