Abstract : The report describes the development of a 'philosophy' or method of approach to the problem of obtaining quantitative predictions of the fluctuating sound field as it propagates in a deep, variable ocean. By combining the use of ray tracing with statistical diffraction theory the method takes simultaneous account of the acoustic effects of the large-scale (mainly) vertical variations in soundspeed, the rough sea surface, internal waves, small-scale turbulent fluctuations in soundspeed, and arbitrary directivities of source and receiver.
