Abstract
Sedimentological study of 20 piston cores from the northwestern Labrador Sea shows that thin bedded distal turbidites are important constituents of the Quaternary strata on the continental slope and rise. Sedimentation on the outer shelf (ca. 500-900 m) is dominated by ice-rafting and hemipelagic deposition. Detailed study of two outer shelf cores reveals a stratigraphic record extending to oxygen isotopic stage 9. Studies of foraminifera and dinoflagellates show that subarctic surface waters penetrated into the northern Labrador Sea during the early-middle glacial stages and pollen data indicate that northward advection of warm air masses occurred at the same time. Microfossil data indicate that late glacial stages were characterized by year around sea-ice cover and arctic surface water, and by the dominance of cold, dry Arctic air masses. Transitions from glacial to interglacial stages are marked by the presence of low salinity melt water.
