Larger morphological sea-floor elementsand longitudinal and transverse bedforms associated to the overflow of the Mediterranean Outflow Water (MOW) are identified in the Gulf of Cadiz after the Strait of Gibraltar. They are located between 400 and 1000 m water depth, being the larger morphological elements indicative of the MOW deceleration, the along-slope circulation of its upper and lower cores, in addition to a secondary circulation oblique to the main flow due to the Ekman effects. In more detail, the identified bedforms are fundamental for understanding the local boundary layer and the progressive bottom friction of the proximal part of the overflow. This is the case of the large sandy 2D / 3D dunes, which are found within the main erosional channels and furrows in high-velocity bottom current settings, which constitute a very good example of dunes in deep-marine sedimentary environments
