Archaeological prospection of the nearshore and intertidal area using ultra-high resolution marine acoustic techniques : results from a test study on the Belgian coast at Ostend-Raversijde

The coastal site of Ostend-Raversijde in Belgium is known for its archaeological artifacts, mainly from Roman and medieval times. In recent years, detailed geophysical and geotechnical investigations have been carried out here to test the efficiency of these techniques for geoarchaeological prospection of the subtidal and intertidal zone. Very high-resolution 2D subbottom profiling using a parametric echosounder evidenced a highly complex system of paleogullies and tidal channels, some of which can be linked to the medieval peninsula Testerep and the drowned settlement of Walraversijde.
