Italian Antarctic Data Center
IT92AW112A
During Austral Summer1991-92 the National Institute of Oceanography and Applied Geophysics - OGS conducted marine geological and geophysical surveys over the Antarctic Peninsular and the Bransfield Strait. During this cruise approximately 3407 km of 30-fold multichannel seismic reflection (MCS) data were collected in the Antarctic Peninsular and the Bransfield Strait between longitudes 50 and 78 degrees West, and latitudes 60 and 68 degrees South.
The surveys were carried out by the research vessel OGS Explora. The digital MCS data were recorded on a SERCEL SN 358 DMX system. The source consisted of an airgun array with a total volume of 71.96 litres fired approximately every 50 meters into a 3000 m cable consisting of 120 hydrophone groups towed at an average depth of 12 m. A GPS + TRANSIT satellite receiver system was used for the navigation.
Processing of the data generally followed a conventional sequence:
Reformat, Trace-sum with differential NMO, Quality control, Amplitude recovery, Deconvolution, Velocity analysis, NMO corrections, Mute, Trace weighting, Stack, Mixing, Filter, Balance.
