Resumo
Multibeam bathymetry and high-resolution seismic data obtained during the RIGEL1116 oceanographic survey, have allowed to study the morphology of the Algeciras submarine canyon (NE Strait of Gibraltar). Three sectors (headwall, middle and distal) have been defined by dominant processes responsible for their formation and evolution. In the headwall sector, the general presence of scars around the canyon head and along its steep wall are cover in the seafloor by sediments reworked and redistributed by contouritic processes. Erosive processes are dominant in the middle sector especially in the incisive gullies (eastern flank) and crescent-shaped bedforms along the distal sector (thalweg and E wall) indicating sediment reworking caused probably by the interaction of the Mediterranean water mass.
