In Austral Summer 1994-95 the National Institute of Oceanography and Applied Geophysics - OGS conducted marine geological and geophysical surveys over the Antarctic Peninsular. During this cruise five (5) research programmes were conducted for a total approximately of 4469 km of multichannel seismic reflection (MCS) data. The research programmes were: SEDANO (SEdiment Drifts of the ANtarctic Offshore) with 1340 km of MCS data; SITE SURVEY, ODP Proposal # 452 (Antarctic Glacial History and Sea-Level Change) with 507 km of MCS data; SANSCRITO (Seismic ANalysis SCotia Ridge Tectonic Outcome) with 1990 km of MCS data and ANGELINA (ANtarctic GEophysical Long range INternational Acquisition programme) with 632 km of MCS data.

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 two GI guns with a total volume of 6.7 litres fired approximately every 25 meters into a 1500 m cable consisting of 120 hydrophone groups for the 30-fold profiles. A GPS + TRANSIT satellite receiver system was used for the navigation.

Processing of the data followed a detailed sequence:

Quality control, Amplitude recovery, Deconvolution, Velocity analysis, Multiples attenuation, NMO corrections, Mute, Trace weighting, Stack, F-X Deconvolution,Filter, Balance.
