Abstract

The Greenland—Norwegian Sea (Fig. 1) connects the northeast Atlantic and Arctic Oceans. Neither the plate tectonic evolution nor the paleooceanography of the Greenland—Norwegian Sea can be discussed effectively independently of the Eurasia Basin to the north, the northeast Atlantic to the south, or the Labrador Sea and Baffin Bay to the west. In oceanographic or sedimentological terms the northeast Atlantic and Greenland—Norwegian Sea area, hereafter referred to as the GNSA, have been the battleground between polar and subtropical water masses over the last 3 million years (Kellogg, 1975; Ruddiman and McIntyre, 1976; Schrader et al., 1976). Since polar water penetrated southward almost to the Azores during glacial extremes, a volume dealing with the Arctic must also stray that far south. North Atlantic Deep Water, formed in the Greenland Sea, flows over the Faeroe—Iceland—Greenland transverse ridge. The subsidence and breaching of this previous land bridge was a major event in the paleooceanography of the North Atlantic (Vogt, 1972a; Nilsen, 1978, Thiede 1979, 1980).
