Italian Antarctic Data Center
IT89A13B
During austral summer 1988/89, the National Institute of Oceanography and Applied Geophysics - OGS conducted marine geological and geophysical surveys off Wilkes Land, and around the Balleny Islands. During this cruise 3045 km of 30-fold multichannel seismic reflection (MCS) data were collected between longitude 152 and 169 degrees East, and latitude 60 and 68 degrees South.
The surveys were carried out by the research vessel OGS Explora. The 12 second, 4 ms sample rate, digital MCS data were recorded on a SERCEL SN 358 DMX system. The source consisted of an airgun array with a total volume of 45.16 litres fired 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 navigation.
Processing of the data generally followed a conventional sequence: Reformat, Trace-sum with differential NMO, Resample to 8 ms, Quality control, Amplitude recovery, Deconvolution, Velocity analysis, NMO corrections, Mute, Trace weighting, Stack, Mixing, Filter, Dynamic trace equalisation.
