| Summary: | During Austral Summer1990-91 Istituto Nazionale di Oceanografia e di Geofisica Sperimentale (OGS) conducted marine geological and geophysical surveys over the Weddell Sea and the Antarctic Peninsular, in the Ross Sea, and in the Balleny Zone of the MacQuarie Triple Junction. During this cruise approximately 3560 km of 30-fold multichannel seismic reflection (MCS) data were collected in the Weddell Sea and the Antarctic Peninsular between longitudes 37 and 56 degrees West , and latitudes 59 and 62 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 45.16 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. |
