Integration of geomorfologic , structural and seismo-stratigraphic data, collectedin the Ligurian sea has provided the realization of new and most detailed marine cartography. In marine areas with different tectono-stratigraphic framework and geologic evolution ad WesterLigurian Margin (SanRemo) , eastern Ligurian Margin (Laspezia) and in the northern Tyrrenian Sea (Isola D’Elba) the interpretation s of the new geolphysical data show, in some case, relevant scientific results.
