Water mass footprints in uneven turbidite system development in the Alboran Sea

Multidisciplinary work between oceanography, geomorphology and sedimentology has uncovered evidence explaining the uneven development of the turbidite systems (TSs) in the Alboran Sea. Nine TSs have been mapped in the Spanish margin, ranging from sandy to mixed sand-mud fans, and which become sandier towards the Strait of Gibraltar; in contrast TSs do not develop in the Moroccan margin, where three canyons incise the continental slope but there is no TS formation. We interpret that the uneven development of TSs in the two margins and their variable architectures are conditioned by the interaction of alongslope with downslope processes. Two different interaction scenarios with varying intensities are proposed.Versión del edito

INFORME CIENTÍFICO-TÉCNICO de la Campaña RIGEL1116

Report on the geophysics and seabed sampling made on the submarine canyon of Algeciras to know its geological, geomorphological and benthic characteristics. In addition, a series of underwater mounds were studied in two sectors of the northern margin of the Alboran Sea.Instituto Español de Oceanografí
