Description
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 SERDRAKE (SEismicResearch in DRAKE passage) programme was a seismic exploration across the Central Scotia Sea, from the South Orkney Islands to the Falkland Plateau, collected between longitude 42 and 47 degrees West, and latitude 51 and 60 degrees South. During this programme 1052 km of 30-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 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.
