Late Neogene contourites in NE Baffin Bay - West Greenland margin: The signature of a proto-Irminger Current?

Abstrakt

Remarkable mounded drifts and contourites characterise the late Neogene succession of the West Greenland continental margin in NE Baffin Bay. These ocean current deposits are observed over two stratigraphiclevels: above a middle Miocene horizon and above an incised conformity of probable early Pliocene - late Mioceneage. The upper Miocene unit displays a 500-1200 m thick mounded sediment prism, covering an area of 100 x150 km across the central shelf. The significant presence of fossil contourites in the late Neogene sediment record suggests that pervasive geostrophic currents invaded the West Greenland shelf margin prior to onset of glaciations, possibly forming a vigorous equivalent to the present day Irminger Current.
