Coarse-fraction studies of sediments recovered during ODP Leg 104 are used to reconstruct paleoclimatic and paleoceanographic environments on a time scale of 0.1 to 0.5 m.y. for the past 20 Ma. These investigations suggest that relatively warm climates and isolated deep water conditions prevailed prior to 13.6 Ma and between 5.6-4.8 Ma. The first major deep water outflow from the Norwegian-Greenland Sea into the North Atlantic took place at about 13.6 Ma. Progressive cooling linked to increased deep water renewal in the Norwegian-Greenland Sea appears to have occurred between 13.6-5.6 Ma and 4.8-3.1 Ma. A major onset of ice-rafted debris is recorded at 2.56 Ma. Terrigenous coarsefraction components show important fluctuations with two major peaks during the past 0.8 Ma.
