Abstract : The character of echo sounding profiles can be used to estimate the presence and magnitude of microtopography or bottom roughness. These are sea floor features whose lateral dimensions are smaller than the illuminated area and cannot be resolved by conventional vertical-beam echo sounding techniques. Vertical roughness may be estimated by studying the character of the returned signal. To test this, a laboratory experiment was conducted. The dependence of the reflected signal on the roughness of the surface was measured. (Author)
