| Summary: | During austral summer1996/97, the Istituto Nazionale di Oceanografia e di Geofisica Sperimentale (OGS), on board the research vessel OGS-Explora, conducted marine geological and geophysical surveys along the Antarctic Peninsula. The TENAP (cenozoic Tectonic Evolutionof the Northem Antarctic Peninsula) programme was a geological and geophysical research project to study the Cenozoic tectonic evolution of the Antartic Peninsula and its borders; data were collected between longitude 59 and 66 degrees West, and latitude 61 and 64 degrees South. During this programme 702.5 km of 30-fold multichannel seismic reflection (MCS) data, 16 second records, 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 60.5 litres, using the Single Bubble methodology, 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. |
