Аннотация: Four cores of 1–3 m length recovered by gravity corers from the Laptev Sea and the East Siberian Sea (Russian East Arctic shelf) were subjected to paleomagnetic studies. The latter together with radiocarbon dating and magnetic susceptibility allowed to make a stratigraphic reference to several other sections of marine sediments obtained in the shelf. The distribution of the Late Pleistocene-Holocene sediments along the shelf of the East Arctic seas of Russia appears to be controlled by the hypsometric position and association with certain geomorphological elements of the relief. All cores revealed a common trend of gradual decrease of inclination downcore compared to the current dipole inclination at the coring sites. Several, well-defined shallow positive and negative inclinations have been identified which could reflect geomagnetic excursions in the Holocene or at the Holocene-Pleistocene boundary.
