Critical reviews of the available seismic records and analyses of CTD data in the Alboran Sea have changed the previous interpretations about the types of deposits making up the nearsurface sediments of the Alboran Sea. During the last 20 years many studies about sedimentation in the Alboran Sea suggested that turbiditic fans, gravitative deposits and hemipelagites characterized the slopes and sub-basins of the Alboran Sea. The new results suggest the dominance of contourites interrupted by submarine fans and sedimentary instabilities in those physiographic domains 0
