Abstract : This report summarizes research on the acoustic interaction with the seafloor, carried out during 1982 at Applied Research Laboratories, The University of Texas at Austin. Major topics considered are the role of scattering from a rough substrate in areas having thin sediment cover and the development of geoacoustic measurement techniques for use in shallow water. Other topics include bottom interaction processes in shallow water, bottom interaction at higher frequencies, and propagation in range variable environments.
