Reconstruction of ice complex remnants on the eastern Siberian arctic shelf
Abstract Based on the analysis of seafloor topography together with historical, geological and palaeogeographical data obtained from published and archived sources, the position of former Ice Complex (IC) islands has been reconstructed. Within the Laptev Sea shelf and in the western part of the East...
