Capbreton canyon runs in an east-west direction parallel to the northern Spanish coast, in the Bay of Biscay, for more than 300 km reaching depths of more than 3,000 m. Within the framework of the European LIFE IP INTEMARES project, some marine areas are being studied and could be protected due to their importance for habitats, according to the Natura 2000 Network. One of these areas is a sector of the Capbreton submarine canyon system, off the coast of the Basque Country. During two oceanographic surveys carried out in the framework of this project, bathymetric, backscatter and high-resolution parametric data were acquired, as well as direct samples and video transects of the seabed. A geomorphological characterization of this sector is being carried out. The area includes a section of the main canyon with meandering morphology, where numerous terraces and erosive escarpments are observed. On its southern slope, there are tributary channels perpendicular to the Spanish coast, which ...
