Quasi-synoptic hydrological data collected in the Western Alboran Sea, during a glider cruise, dedicated to sample the Western Alboran Gyre (WAG) in late fall 2020 have been used to examine the distribution of the water masses in the region. The spatial variability has been addressed by means of a Support Vector Machine (SVM) classification applied...
Different classification techniques of water masses have been developped using the potential temperature-salinity (θ-S) diagram and its volumetric analysis.
In this study, we propose a new method to automatically classify water masses via a supervised machine learning algorithm based on the K nearest neighbors (Knn), in the potential density and po...

The Alboran Sea (Western Mediterranean) is a relatively s...
Earthquakes are the most commonly cited cause of offshore slope failure, followed by high sedimentation rates and ensuing pore pressure build-up. In the South Alboran Sea, the moderate seismicity (Mw = 6.4) of the strike-slip Al Idrissi Fault Zone does not appear to control directly the landslides distribution. To provide a preliminary geohazard as...
The seafloor of the Alboran Sea reflects its complex tectonic, sedimentary, and oceanography dynamics as a consequence of the geological context, involving interaction between the Eurasian and African plates, and oceanographic context, as it is where the Atlantic and Mediterranean waters meet. Their physiography has a semi-enclosed configuration ch...

Monitoring the water and sediment quality of the Port Tanger Med 1, Morocco
Mapping the distribution of marine species plays a particularly important role in resource management. Prospecting campaigns were carried out between 2015 and 2017 along the Fnideq-Tamernout area of the occidental Moroccan Mediterranean Sea, through artisanal boats equipped with hydraulic dredges for shellfish fishing. A total of 1526 samples of Ca...
A new basin-scale comprehensive view of contourite features, turbidite systems, and mass-wasting deposits comprising the Spanish and Moroccan margins and basins of the Alboran Sea has been achieved after a new detailed seismic stratigraphic analysis and the construction of sedimentary maps for the Pliocene and Quaternary sedimentary units. Multiple...
The Djibouti Ville Drift is part of a contourite depositional system located on the southern side of the Djibouti Ville Seamount in the Alboran Sea (Western Mediterranean). The sedimentary record of a core located in the drift deposits has been characterized to achieve the possible sediment sources for the Saharan dust supply and the paleocurrent v...
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).

A seismic analysis of the Pliocene and Quaternary stratigraphy was conducted in the Alboran Sea (westernmost Mediterranean) using more than 1250 profiles consisting of single- and multi-channel seismic records. This allowed for the updating and renaming of the stratigraphic boundaries and the establishment of a new Pliocene and Quaternary seismic s...
The analysis of a data set of multibeam bathymetry plus high resolution seismic and parametric profiles allow us to characterize the geomorphologic units on the Alboran Sea-floor as well as the evolution of morpho-sedimentary systems along the Pliocene and Quaternary, later than the main erosive Messinian event. Since the opening of the Gibraltar S...
Analyses of trace metals and organic contaminants (PCBs, PAHs, and PBDEs) were carried out in soils and sediments collected in different areas from the North of Morocco, in the framework of several bilateral projects between the Moroccan CNRST and the Italian CNR.
Results indicated a situation of absent or low contamination in lagoons and salt mar...
Several morphosedimentary signatures produced by the interaction between alongslope and downslope sedimentary processes have been identified in the Pliocene and Quaternary records as well as on the present-day seafloor of the Alboran Sea. The scenarios of interaction move between two-end-members: from bottom currents dominating gravity flows to gra...
We present an interdisciplinary study of the geomorphology, sedimentology and physical oceanography of the Alboran Sea (south-western Mediterranean Sea) to evaluate the potential role of bottom currents in shaping the Spanish andMoroccan continental margins and adjacent basins. Bathymetric and seismic data have allowed the recognition of the contou...
High resolution seismic data have allowed establishing the chronostratigraphic framework of quaternary rhodanian deposits. The study of cored sediments from the rhodanian continental shelf allows specifying some characteristics of the late quaternary deposition pattern. The chronological calibration (14C and palaeomagnetism) and the correlation bet...
