abstract = {The seabed morphology and the sub-bottom characteristics of a sector of the Gulf of Cádiz
continental slope have been analyzed from different data sets. The morphological characteristics,
the type of sediments and dominant benthic species of Gazul mud volcano and adjacent areas have
been studied. The morphological characteristics identified were grouped in fluid escape related
features, bottom current features, mass movement features, structural features and biogenic
related features. Additionally, dominant benthic species associated to fluid escape and seepage,
hard substrates or soft bottoms have also been indicated in these features. A bottom current
velocity analysis allowed relating the morphological features with the different sedimentary and
oceanographic processes as well as the benthic habitats and that currently occur in the mud volcano
and nearby areas. The major factor controlling these features and their associated benthic habitats is
the interaction of deep water masses with the seafloor topography. At high velocities, authigenic
carbonates can be exhumed and colonized by sessile suspensivorous species associated with hard
substrates such as cold-water corals, anthipatarians and large sponges. Mounds and diapiric ridges
are found on the depressions and they could be relict structures. Living corals have been found on
raised zones, revealing different oceanographic condition and strong enough currents to favour the
availability of nutrients and organic particles. Chemosymbiotic organisms are very scarce at the
summit and old remains of Lucinoma asapheus indicating past higher seepage activity.},
