The Bari Canyon System (BCS) is a peculiar erosional–depositional feature characterised by two main, almost parallel, conduits emanating from a broad crescent-shaped upper slope region. When viewed in cross sections parallel to the margin, BCS appears markedly asymmetric with a right hand (southern) side that is higher and steeper (about 800 m in relief and more than 30° steep). The left-hand side of the canyon is instead much smoother. As a consequence, bottom currents flowing along the slope from the north enter the canyon and interact with its complex topography leading to preferential deposition on the up-current side of pre-existing morphological relief. Where mass-failure deposits generate morphologic relief, outside the canyon, sediment is preferentially deposited up current (N-ward). BCS includes three main EW-oriented sediment conduits: Canyon C, to the south, Channel B, in the central area …
