We shows preliminary results from high-resolution seismic reflection profiles (1.5kJ Sparker and Chirp), multibeam bathymetry and oceanographic surveys (CTD and ADCP) carried out in 2011 and 2013 south Capo Vaticano (southern Tyrrhenian Sea, Italy). The collected data reveal the widespread occurrence of contourites on the upper slope-outer shelf sectors. These newly discovered contourites are interbedded with hemipelagic deposits and locally with turbidite and/or mass wasting deposits. The interaction between along slope bottom currents and downslope processes can be observed both on the seafloor and within buried depositional sequences of upper Pleistocene age. Sequence stratigraphic interpretation suggests that Capo Vaticano contourite deposits developed within high-order depositional sequences formed during upper Pleistocene eustatic cycles, possibly during lowstand phases.
