dc.description.abstract | This is an interdisciplinary study that combines morphoseismics, sedimentology and numerical modelling to elucidate at different scales
of resolution the influence of alongslope processes on the turbidite systems (TSs) and canyons in the Alboran Sea (southwestern
Mediterranean). Nine TSs are mapped in the Spanish margin (La Linea, Guadiaro, Baños, Torrenueva, Fuengirola, Salobreña, Sacratif,
Calahonda and Almeria) and two in the Alboran Ridge (Piedra Escuela and Al-Borani). In the Moroccan margin, there are only two
canyons (Ceuta and Nekor). Distinctive morphoseismic and sedimentological signatures from TSs and canyons have enabled three regional
models of alongslope influence to be distinguished: a) Alongslope processes are dominant. This scenario characterizes the canyons of the
Moroccan margin. The diagnostic signature is the lack of leveed channels and lobes at the Ceuta and Nekor Canyon mouths. b) Different
degrees of interplay exist between alongslope and downslope processes. This scenario occurs in the TSs of the western Spanish margin. Here,
the alongslope influ-ence on TSs (La Linea, Guadiaro, Baños, Torrenueva and Fuengirola) is evidenced by the lack of overbank deposits
in the La Linea and Guadiaro Canyons and an alongslope trend in the morpho-architecture of the channelized lobes and in the textural
distribution of canyon/channel deposits (mass-flow deposits and turbi-dites). Both signatures indicate sandier TSs as well as Bouma
turbidite sequences lacking the finest levels towards the Strait of Gibraltar. Local intercalations of contourites are also present in the
Guadiaro lobe deposits. c) Downslope processes are dominant. This scenario characterizes the TSs of the eastern and central Spanish margin
and Alboran Ridge. There, TSs seem to be controlled solely by the characteristics of the downslope gravity flows that transport sediment.
The hydrodynamic and sediment dispersion models confirm that the main oceano-graphic factors governing the variable alongslope
influence in TSs and canyons are the following: a vigorous WMDW flow along the Moroccan margin and the energetic Atlantic Jet,
western Atlantic anticyclonic gyre and general acceleration of the Mediterranean waters towards the Strait of Gibraltar, along the
western Spanish margin. This study demonstrates the pivotal role that alongslope processes can play in the onset and formation of TSs and
canyons at continental margins. | es |
