Abstract
During the oceanographic cruise, “BOCCHE 2003” (Project: Geologia e geomorfologia terrestre e marina dell’insieme Corsica-Sardegna e della Toscana e applicazioni” PIC- INTERREG III) and “Sardegna 2010” (Project MAGIC – Protezione Civile Italiana”), Multibeam, Side Scan Sonar and GeoChirp data were obtained and samples of superficial sediment have been taken. The analysis of data highlighted on mobile funds, the presence of complex bedforms associations, typical of continental shelf environment affected by high flow rate currents, both mono or bidirectional. Integrated analysis of sismostratigraphic, Multibeam, Side Scan Sonar and sedimentological data, performed in a GIS environment, allowed to define, the distribution of sedimentary structures and the relative dominant bottom currents. Furthermore, a general circulation pattern of currents that highlights the existence of bottom currents flows westward, opposed to surface flow was assumed.File | Dimensione | Formato | |
