Marine Seismic Reflection
Univ of Texas
This survey was conducted in 1979 in the South Atlantic Ocean, near the Rio Grande Rise by the University of Texas (R/V Fred H. Moore). Navigation used was transit satellite with dead reckoning for the ships heading and speed. The streamer used was a 6-channel streamer (group interval 100 m) with 2 sonobuoy traces recording to a DFS 4 (low filter=8Hz; high filter=62Hz). Source to near trace offset was 263 m. The seismic source for these was three Bolt air guns (4500 cubic inces, 450 psi, source depth 10 m).
