L'énigmatique Fosse Centrale de la Manche : une approche de sa morphologie et de son remplissage par géophysique haute résolution

New high resolution geophysical results from EM1000 swath-bathymetry system and Very High Resolution reflection seismic data are presented. A Neogene tectonical origin of the Hurd Deep and the interplay of erosion, sedimentation during the last glacial, inter-glacial periods are here argued by interpretation of these results in term of geomorphology and sequence stratigraphy.
