| Summary: | During austral summer1989-90 the Istituto Nazionale di Oceanografia e di Geofisica Sperimentale (OGS) conducted marine geological and geophysical surveys off Wilkes Land, and around the Balleny Islands. During this cruise 1284 km of 30-fold multichannel seismic reflection (MCS) data were collected between longitude 165 and 176 degrees East, and latitude 61 and 66 degrees South. The surveys were carried out by the research vessel OGS Explora. The 14 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 22.5 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. |
