Objective The basic objective of the project is to provide accurate, valid, and easily-used 3-D models capable of realistically predicting the propagation of sound in the sea. The models will have clearly defined domains of applicability, for example range of frequencies, range of depth, bottom morphology and quality, etc. The specific objectives of the project are: - 3-dimensional integrated numerical models and computer codes for workstations or personal computers. - models which will incorporate the key environmental parameters which influence sound propagation in the sea, i.e. temperature, salinity, surface roughness, bottom morphology, sub-bottom structure, range inhomogeneities, volume attenuation. - model validation versus actual experimental data and benchmark problems. - emphasis on shallow-water propagation models for frequency ranges from 10-1000 Hz and depth ranges from 10-500 m. - realistic surface-boundary, bottom-interface and sub-bottom influences. A study will be made of the influence of weak inhomogeneities in the water column, that make the problem 3-D. In considering the sea-bottom, influences on propagation in the form of interface waves and shear waves will be included. Experimental data used in the project for the validation of the models are in existence from MAST I and other previous projects.
