Abstract: Birth of an ocean Deep-water formation in the northern North Atlantic and the Arctic Ocean is a key driver of global thermohaline circulation and hence of global climate. The lack of sediments from the Arctic's deep-sea floor has hampered research into this area, but this changed when drill cores were recovered from the central Arctic Ocean in 2004, during the ACEX experiment. This unique 428-metre-thick Cenozoic sediment sequence preserves a critical piece of palaeo-environmental history: the advent of the Arctic Ocean in its current form. The gradual opening of the Fram Strait resulted in a change from a land-enclosed lake-like water body to an estuarine 'Black Sea type' phase with variable ventilation, and finally to the fully ventilated 'ocean' phase, some 17.5 million years ago.
