Abstract

The role of the submarine canyons on the coastal sediments capture in the Gulf of Taranto In the submerged area of the Gulf of Taranto many submarine canyons are located. They play an important role in the transfer of terrigenous deposits from coastal toward deeper basins. When the sediments, coming along the shelf, intersect the heads of the canyons, fall down in his bed flowing toward greater depth as gravity flows. Moreover to such transfer of sediment, the erosion and the widening of canyons, as well as the progressive reduction of the continental shelf, is occurred. The characters of the sediments on the investigated areas underline the role that these forms have in the sedimentary dispersion; the slope and basin deposits show the same characteristics of shelf sediments to testify their origin in coastal areas and allows to suppose the transport ways conditioned by the narrow section shape of the canyons. The sandy deposits located in areas with narrow shelf are transported by coastal currents and captured by canyons heads, where they are trapped and used as source of periodic turbidity currents moving towards deeper areas.
