Abstract

The wide spectrum of the geophysical information was used for compilation of the “Sediment Thickness Map of the Arctic Ocean”. The sedimentary cover includes all un-deformed Meso-Cenozoic (abyssal Arctic Ocean) or Paleo-Cenozoic (shelves) coilogenic stratified sedimentary complexes from the seafloor to the top of the acoustic basement (TAB) was presented at this Map. The belt of deep depressions located either inside shelves or in continental margin-shelf transition zones ringing the abyssal part of the Arctic Ocean, is clearly visible on the Map.

The demonstrated contemporary crustal thickness map of the Arctic Ocean was compiled using not only existing seismic information and bathymetry but also regional digital gravity dataset. The map vividly illustrates the radical difference in crustal thickness between clearly oceanic regions of the Arctic Ocean (Eurasian and Canada Basins) and remaining parts with continental or transitional types of crust.
