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)forDORISEngineeringonbehalfofGRTgaz (Engineering centre, Transmission Pipe Department; www.grtgaz.com) which are currently investigating the possibility of laying a pipeline betweenSardinia and Corsica as a spur line from the planned GALSI Project. The Project, ‘‘Alimentation de la Corse en gaz naturel’’, consists of a corridor 100 km long and 1.0 km 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 20 km 9 1.5 km), 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 100 m 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/-115 m, is interrupted by four canyon heads which incise the slope and are associated with glide deposits.
