Abstract
The section presents the FGUP VSEGEI seismic knowledge base in the form of a map. It contains data on regional seismic surveys (CDP, seismic refraction, DSS and many others). All the survey data were selected from open access and include activities from 1957 to the present. Data obtained by Russian companies (OAO MAGE, AO Sevmorgeo, OAO DMNG, etc.) and foreign expeditions (AWI, Healy, USGS, etc.) are shown. The correlation chart of the stratigraphic reference of reflecting horizons demonstrates an approach to substantiating the reflected horizon (RH) ages and the opinion of other major researchers and organizations in the region on this issue. A set of composite seismic lines (6 lines) intersecting major geological structures of the northeastern part of the Arctic is shown with a complete seismo-geological interpretation: correlation of reflected seismic horizons (RH) with all seismic recording disturbances (faults) and reservoir velocities observed in the wavefield. Based on seismo-geological lines, conclusions are drawn concerning the structure, age of the basement and sedimentary cover complexes in different geological structures. The inheritance of sedimentary basins from shelves to the deepwater part of the Arctic Ocean is shown. There are three structural maps in the section: the acoustic basement of different ages, the Cretaceous deposit roof (RH pCU) and the Eocene deposit roof (RH UB). Zoning was made for each map, the basement and sedimentary cover structures were identified and characterized.
