Abstract:

LONG-TERM GOALS To develop accurate models for high frequency sound propagation in shallow water sediments. OBJECTIVES The scientific objectives are to 1 quantify the relative importance of scattering and frictional losses in the attenuation of sound in sediment, 2 evaluate and improve existing models of sound propagation and, 3 develop more complete models of sound propagation which can account for the complexity of shallow water sediments.
