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.

Quality and validity

Lineage: 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.
