Cecchini, D. Taliana, L. Giacomini, C. Herisson, B. Bonnemaire] The understanding of the morphology and the shallow geo-hazards of the seafloor is a major focus for both academic and private industry research. On November and December 2009 a geophysical pipeline survey was carried out by Fugro Oceansismica S.p.A. (FOSPA) and FUGRO France (FFSA) for DORIS Engineering on behalf of GRTgaz (Engineering centre, Transmission Pipe Department; www.grtgaz.com) which are currently investigating the possibility of laying a pipeline between Sardinia and Corsica as a spur line from the planned GALSI Project. The Project, "Alimentation de la Corse en gaz naturel”, consists of a corridor 100km long and 1.0km wide along the Corsica-Sardinia shelf. The integration of the multibeam, sidescan sonar and sparker data provided a high resolution seafloor mapping for geo-hazard assessment. In this article the data acquired along a break of slope section (approximately 20km×1.5km), in the eastern sector of the Strait of Bonifacio are described. The area was abandoned during the survey, because of its unsuitability. Indeed, in this area the continental shelf, approximately 100m deep and deepening gently eastward, is characterized by an uneven morphology, with different seabed features such as Beach-rocks mainly NNW-SSE oriented. Also, the continuity of the continental margin, identified around −110/−115m, is interrupted by four canyon heads which incise the slope and are associated with glide deposits.
