| 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. During this cruise there were several resaerch programmes: SEDANO programme included on SDLS 47 and 48, ODP proposal # 452 on SDLS 49, ANGELINA, SANSCRITO and SERDRAKE programmes on this DVD. The ANGELINA (ANtarctic GEophysical Long range INternational Acquisition) programme was a seismic exploration in the Adelaide Fracture Zone on the Pacific Margin, near the Marguerite Bay and the Adelaide Island, collected between longitude 68 and 74 degrees West, and latitude 66 and 69 degrees South. During this programme 631 km of 20-fold multichannel seismic reflection (MCS) data, long 20 second, 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 75 litres fired every 75 meters into a 3000 m cable consisting of 120 hydrophone groups towed at an average depth of 10 m. A GPS + TRANSIT satellite receiver system was used for navigation. |
