Abstract

Several tributaries highly incised in the continental margin merge in the Almanzora-Alías-Garrucha Canyon, on the lower slope of the Vera Gulf. This canyon generated a turbidite system and a submarine fan at the mouth, where a field of large sediment waves developed at about 2500 m water depth. These sediment waves reach maximum heights and wavelengths of 80 m and 4.5 km, respectively, and are preferentially orientated N-S. The sediment waves display an upslope migration and are interpreted as being associated with supercritical turbidity currents.
