Description:
In marine environments the surface of the solid earth is covered by water and can only be mapped with bathymetric methods. As the seafloor is build up by internal and external forces, the submarine morphology preserves information on internal structures and tectonic history. Multibeam echosounding systems continuously map a stripe of the ocean bottom with an acoustic swath. The echo data is processed to calculate a digital terrain model, which can be presented as a bathymetric map or a perspective view. Using calculated illumination details in the images are enhanced, thus revealing much more morphotectonic information than in custom bathymetric maps. Seamounts and active continental margins are striking features of submarine morphology. The dynamic history of these areas is demonstrated in bathymetric images.
