1. Morpho-sedimentary study of the continental margin.
The morpho-sedimentary study is carried out using bathymetric prospecting with 100% covering of the sea floor by means of a high-resolution multibeam echosounder to provide cartography (digital terrain models) and identification of the morphological elements of the study area. To identify the units and thickness of recent unconsolidated sediment sequences we use a high-resolution parametric reflection continuous seismic profiling system. We also construct sonographic mosaics of the area based on acoustic reflexion, which are complemented with direct data as visual sampling (photo and video). The application of automatic texture classification programs of the sea floor is an important methodological improvement since it includes direct data (trawl sampling, photogrammetry, ROV, etc) of the different types of sea floor, allowing calibration and supervision of the system.
