Tomographic profiles permit clear discrimination of the soft sediment above the basement and thus allow the determination of the total volume of sediment above the seismic bedrock, estimated at about 265,000 m 3. Processing data with 3D techniques enables images of the structure and the thickness of the lithotypes to be reconstructed, thus leading to large-scale, realistic estimates of the total quantity of material to be excavated or dredged. The substratum has an articulated morphology Vp images unravel small steps in the basement probably related to structural discontinuities (e.g., faults). Low Vp (1.8-4.5 km/s) deposits belonging to terraced calcarenites (Upper Pleistocene in age) are also well imaged they are about 8 m thick and lie below loose sand deposits (Vp = 1.5 km/s). Seismic tomography expands existing knowledge of the harbour subsoil with a penetration of about 20 m, illuminating the Lower Pleistocene bedrock (Marsala calcarenites) that corresponds to high-Vp regions (Vp > 4.5 km/s). Using a hydrophone spacing of 2.5 m and shot spacing of 5 m, very high resolution quality data were recorded. Seismic data were collected along four hydrophone arrays on the sea-bottom and via a Watergun as seismic source, in order to plan dredging operations in the harbor. We present high-resolution Vp models of the Capo Granitola harbor, Sicily (Italy) obtained by first arrival traveltime tomography. capo n koi Lyrics: Capoxxo, were bros, he got hoes, yea you know / And we got the flow, and the smoke and.
