Research output


The vast bathymetric depression of the Podvodnikov Basin lies between the Lomonosov Ridge and Mendeleev - Alpha Ridges, bounded by the East-Siberian Sea shelf from the south and by the Makarov Basin - from the north. Sea depth in the Podvodnikov Basin varies from 800 m to 2700 m in the same direction. The Podvodnikov Basin has a benched structure and is considered to be a part of the terraced continental slope. The seismic data divide the southern terrace of the Podvodnikov Basin into western and eastern parts, separated by the prominent Geofizikov Spur and its southern continuation as a deeper structure of the acoustic basement. Total thickness of the sedimentary cover here reaches 8 km. The sedimentary cover of the Podvodnikov Basin is subdivided into six seismic-stratigraphic complexes, dated from late Permian to Holocene by correlation with ACEX well on the Lomonosov Ridge and exploration wells on the Alaska shelf. Integrated geophysical data interpretation and modeling classify the Basin's crust as stretched continental, with thickness of the crystalline crust from 10 to 23 km.
