The integration of results obtained from the reinterpretation of seismic and acoustic records and analyses of CTD (Conductivity, Temperature and Depth) data has allowed to demonstrate that along-slope are the dominant processes, contrary to established thinking up to now, which considered that turbidity and mass-transport processes were the prevailing processes. Contourites features, evolving under the action of several water masses, are the main morphosedimentary features that characterize the margin and basin seafloor from the shelf-break (> 90 m water depth). Several types of contourite features have been characterized, depositional (plastered, sheeted, elongated-separated, & confined); erosive (moats, channels & furrows) and mixed (contourite terraces). These features are interrupted locally by the construction of turbiditic fans, mainly in the Spanish margin, and by sedimentary instabilities that affect locally to the slope and seamounts. This new morphosedimentary sediment view of the Alboran Sea reveals for the first time the important role of sedimentary processes (transport, sedimentation and erosion) associated with five major water masses, one of Atlantic origin (Atlantic Water -AW-), three of Mediterranean origin (Winter Intermediate Water -WIW-, Levantine Intermediate Water -LIW-, Western Mediterranean Deep Water -WMDW-), and a local mixed water that result from the blending of AW and WMDW. These currentdominated processes have three different domains of acting: 1) on the large-scale morphology of the physiographic provinces; 2) on the small-scale morphosedimentary features characterizing the physiographic provinces; and 3) on depositional model of the adjacent downslope sedimentary systems Peer Reviewed 2014-01-21T12:32:18Z 2014-01-21T12:32:18Z 2013-01-28 2014-01-21T12:32:18Z comunicación de congreso http://purl.org/coar/resource_type/c_5794 Dialogue Between Contourite and Oceanography processes International Workshop: 50 (2013) http://hdl.handle.net/10261/89687 en none
