ResumoThe GEBRA '93 (Geological Evolution of the Bransfield Basin) survey was carried out in December 1993 in the Bransfield Strait (NW Antarctic Peninsula) and adjacent areas, onboard BIO Hesperides. The geophysical data acquired allow to characterize the morphostructure, sediment cover and magnetic anomalies of the SW-NE trending Central Bransfield Basin. Some transverse shifts and tresholds, together with alongbasin volcanic alignments, complicate the morphology and seismic structure of what otherwise would have been a long, continuous axial trough opened on a crust under extension. A major submarine valley, named Gebra Valley has also been identified
