  Processed seismic data of Cruise BGR96 1996

The BGR Antarctic cruise 1996 from 29th December 1995 to 6th February 1996 with M.S. AKADEMIK NEMCHINOV was designed to acquire new marine geophysical data for a better understanding of the geological processes, timing, occurrence and location of rifts of the initial break-up of southern Gondwanaland. A total of 3,836 km of multichannel seismic reflection data have been collected in the areas of the Cosmonaut Sea, the Astrid Ridge, the Lazarev Sea and the southern Agulhas Plateau in parallel with magnetic and gravity measurements. In addition magnetic and gravity measurements were carried out on transit. Major new observations of the collected MCS data include: (1) Volcanic rocks play a major part in the construction of the Astrid Ridge and also of the Agulhas Plateau. (2) The early opening of the Lazarev Sea was associated with excessive volcanism resulting in the emplacement of a voluminous volcanic body characterized by an internally divergent pattern of seaward-dipping reflectors. (3) The Astrid Fracture Zone continues in form of a sediment-filled basement depression flanked by distinct basement highs into the Lazarev Sea, and apparently swings to the west parallel to the coast of Queen Maud Land. (4) The thickness of sediments in the Cosmonaut Sea overlying oceanic crust of inferred Early Cretaceous age is in excess of 4s (twt), i.e. about 6,000 m. Three regional seismic markers of inferred Cretaceous, Late Eocene-Oligocene and Middle Miocene ages subdivide the sedimentary column.

Statement
During the period from 29th December 1995 to 6th February 1996 BGR acquired seismic lines at the Agulhas Plateau and in the Lazarev Sea. The lines BGR96-002A, BGR96-003 and BGR96-005 consist of raw data. The lines BGR96-001, BGR96-002, BGR96-004, BGR96-005A, BGR96-006, BGR96-007, BGR96-008, BGR96-009, BGR96-010, BGR96-011, BGR96-012, BGR96-013, BGR96-013A, BGR96-014, BGR96-015, BGR96-015A, BGR96-016 and BGR96-100 are stacked data.
