| Summary: | During austral summer1994/95, the Istituto Nazionale di Oceanografia e di Geofisica Sperimentale (OGS), on the research vessel OGS-Explora, conducted marine geological and geophysical surveys along the Antarctic Peninsula. The SANSCRITO (Seismic ANalysis SCotia RIdge Tectonic Outcome) programme was a seismic exploration in the Scotia Sea for undestand the tectonic history and evolutin of the region, collected between longitude 45 and 54 degrees West, and latitude 59 and 65 degrees South. During this programme 1990 km of 30-fold multichannel seismic reflection (MCS) data, long 8 seconds, 4 ms sample rate, were recorded on a SERCEL SN 358 DMX system. The source consisted of an airgun array with a total volume of 80 litres fired every 25 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 |
