Compétences visées

Learning Outcomes:
The aim of the course is to convey to those students with the geological processes giving shape to oceanic basins, and in the active geological, geophysical and sedimentological processes in oceanic domains. As such the course aids in preparing the students for a multidisciplinary and polyvalent formation as hydrographer.
Identification, use, application, correspondence, interaction and problem solving of the earth's geology and environmental science
