Physical properties of sediment cores from the Arctic Ocean

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.
