Аннотация: A seismic stratigraphic framework and basin fill geohistory for Arctic Ocean basins ispresented based on data collected by several Russian Government organized expeditions to theArctic Ocean. This analysis tied together seismic stratigraphic interpretations for the shelf and thedeep-water part of the ocean. The stratigraphic framework is based on age data derived from linearmagnetic anomalies in the Eurasia Basin, borehole data for the Lomonosov Ridge and Alaska Shelf,and correlations with various regional geological events. Six seismic boundaries were identified andtraced regionally over large areas. We present as a hypothesis that the Arctic Ocean probably wasformed during four phases with different kinematics: 133-125 Ma – Canada Basin opening, 125-80Ma – superplume-related tectonics and magmatism in the Alpha-Mendeleev Rise area and adjacentbasins, 80-56 Ma - strike-slip fault tectonics, and 56-0 Ma – Eurasia Basin opening. The timeinterval of 45-20 Ma appears to be a period of large-scale vertical intraplate movements and normalfaulting. Climatic events are recorded in the sedimentary cover of the Arctic Ocean.The analyses were based on a comprehensive dataset that included more than 23,000 km of2D seismic lines, which were acquired in the deep-water part of the ocean, supplemented by a largenumber of federal and commercial seismic lines, which were acquired for the Russian shelves during the past 10-15 years. In addition, special multiple Russian expeditions collected samples onscarps of the Mendeleev Rise that served as ground truth for the seismic interpretation.
