The long term scientific objective of this research is to improve our understanding the physics and mechanisms of acoustic bottom interaction and reverberation, including acoustic penetration, propagation, attenuation and scattering in elastic heterogeneous rough sea beds at low and mid frequencies. The specific goal of this research is to develop a model of sea bed scattering due to volume heterogeneity consistent with existing propagation models and therefore to provide a self-consistent theoretical basis for improving and upgrading current bottom interaction codes such as GABIM.
