Sediments of the Arctic Ocean are recorders of oceanographic and climatic evolution in the northern hemisphere, The sedimentary history is reflected in the sediment physical properties, thus knowledge about them is a key to its Interpretation particularly within the Quaternary.In this study, 29 sediment cores from the eastern Arctic Ocean were investigated On porosity, wet bulk density and ten cores on compressional (P-) wave velocity. Analysis of these parameters permits interpretations about the sedimentary conditions in the Amundsen and Makarov Basins and on the Lomonosov Ridge, Yermak Plateau and Morris Jesup Rise.The distribution of 25 sediment cores throughout abyssal hill and abyssal plain locations of the eastern Arctic Ocean show specific distribution patterns of wet bulk densities and porosities which characterize the sedimentary regions. On the Yermak Plateau undisturbed pelagic sedimentation predominates. The Lomonosov Ridge and the Morris Jesup Rise are characterized by winnowing.
