deeply penetrated by acoustic energy; 3, smooth seafloor scarcely penetrated by acoustic energy (biogenic
sands); 4, rough seafloor not penetrated by acoustic energy (calcarenites with sandy spots and morphological
highs, mostly rocky); 5, prograding surfaces; 6, slope zone; 7, submarine slumping; 8, Posidonia meadows; 9,
shelf edge; 10, main break in slope; 11, canyons and valleys; 12, volcanic peaks; 13, submarine fan deposits;
