Processed seismic data of Cruise BGR85 1985

A geophysical reconnaissance survey across oceanic fracture zones has been carried out by the BGR in the eastern North Atlantic using S.V. PROSPEKTA. The geophysical measurements, including multichannel seismic reflection profiling, magnetics and gravity were concentrated on three oceanic crustal areas of Mesozoic crust which are crossed by the Hayes Fracture Zone, the Atlantis Fracture Zone and the Kane Fracture Zone respectively. 24 geophysical lines with a total length of 5,362 km have been measured during the time period from 25th October to 4th December 1985. Besides intracrustal seismic events a deep coherent seismic event is often recognizable in the monitor records between 10 - 12 s (TWT) along several lines, which probably is a reflection from the crust-mantle boundary.

Explanation: siehe dazu die angegebene Durchführungsbestimmung

Statement: During the period from the 25th October to the 4th December 1985 BGR acquired 24 seismic lines off West Africa in the Canary Basin at the Hayes, Atlantis and Kane Fracture Zones. The lines from BGR85-01B to BGR85-15 consist of raw data, the lines BGR85-23, BGR85-24A, BGR85-24B and BGR85-25 are stacked data, the lines BGR85-16, BGR85-17, BGR85-18, BGR85-19B, BGR85-20A, BGR85-20B, BGR85-21, BGR85-22, BGR85-26, BGR85-27 and BGR85-28 are migrated data.
