Underwater geomorphology of the rocky coastal tracts between Finale Ligure and Vado Ligure (western Liguria, NW Mediterranean Sea)
2011
Abstract The western part of the Liguria Region (NW Mediterranean Sea) has been reported as tectonically stable to slowly uplifting since the Late Pleistocene. Despite good knowledge of the coastal geomorphological features above sea level, very little information is available on the characteristics of the underwater coastlines. Direct and indirect underwater surveys carried out in the area between Vado Ligure and Finale Ligure (Western Liguria) allowed the identification of several surfaces of marine origin, in four sites, at three depth intervals: 8–13 m, 17–23 m and 27–30 m. These values appear to be in bathymetric analogy with those reported by other authors along the Italian coastlines, in areas where the tectonic movements along the Late Quaternary are considered negligible on the basis of the elevation of the MIS 5.5 shoreline. Although few chronological constraints are possible due to the lack of dateable material, the marine morphologies identified in this study constrain their ages to the Middle and Late Quaternary.
