MARINE GEOLOGY FOR HYDROGRAPHY 2
The course starts to the study of the marine and ocean basins floors and underlying layers with features, sediments, structures and morphodynamics of the ocean basin. In particular the recent technological growth and the use of high resolution seismic stratigraphy are fundamental in the study of the ocean basins referring to the classical and applied Marine Geology. The evolution and the history of the basins are the base of the knowledge and an important help to a wide view of the oceans
To provide the students an integrated view of the evolution of the oceanic and sea floor basins with the necessary notions and concepts to make them able to correctly analyse and interpret stratigraphy with particular reference to the seismic stratigraphy referring to the sedimentary processes and the geological evolution of the ocean basins. That purpose is aimed at also by the exploitation of an integrated and applied approach between geophysics and geological data referring to Mediterranean case histories.
AIMS AND LEARNING OUTCOMES
Focuses on principles of geodynamics of the oceans referring to the continental margin records, shallow water processes and marine geology applied in the context of seafloor resources exploitation and environment useful to human activities. In particular the course is devoted to the introduction to the ocean basin and the principles of the plate tectonics, the continental margin records and the relation to the coast, beaches and shallow water processes during time, and applied marine geology to the seafloor resources, geohazard and hydrography to coastal management.
