Processed seismic data of Cruise BGR 1993

In September 1993, the Federal Institute for Geoscience and Natural Resources (BGR) has carried out in cooperation with Sevmorneftegeofizika (SMNG), Murmansk a 2D-seismic survey of the eastern part of the Laptev Sea shelf. The data format is Society of Exploration Geophysicists SEG Y. During the survey with a total length of 3189 km the 70 km wide New Siberian Basin and two other basins were mapped. In the central part of the New Siberian Basin, a Tertiary sediment thickness of more than 4 km overlying older sediments was observed. Further to the east, a large area covered by lava flows of unknown thickness was investigated. There are no indications of a propagation of real seafloor spreading into the Laptev Shelf and thus the Asian continental crust. Therefore seafloor spreading seems impossible at total spreading rates below 0.7 cm/year, at least for crust of the character which is present here.

Statement

During the period of 5th of September to 28th of September 1993 BGR aquired seismic lines in the Laptev Sea. The lines BGR93-02, BGR93-03, BGR93-04, BGR93-06, BGR93-07, BGR93-09, BGR93-10, BGR93-12, BGR93-15, BGR93-17, BGR93-18, BGR93-20, BGR93-21, BGR93-23 are processed (migrated) data and the lines BGR93-05, BGR93-08, BGR93-11, BGR93-13, BGR93-14 are processed (stack) data. The lines BGR93-16, BGR93-19, BGR93-22, BGR93-24, BGR93-25 are raw data.
