描述This Topics volume is devoted to a study of sound propagation in the ocean. The effect of the interior of the ocean on underwater sound is analogous to the effect of a lens on light. The oceanic lens is related, as in light propagation, to the index of refraction of the medium. The latter is giv~n by the ratio of the sound frequency to the speed of sound in water, typi ca lly about 1500 m s -1. It is the vari- ation of the sound speed due to changing temperature, density, salinity, and pres- sure in the complex ocean environment which creates the lens effect. Many oceanic processes such as currents, tides, eddies (circulating, translating regions of wa- ter), and internal waves (the wave-like structure of the oceanic density variabil- ity) contri bute in turn to the changes in sound speed‘. The net effect of the ocean lens is to trap and guide sound waves in a channel created by the lens. The trapped sound can then propagate thousands of miles in this oceanic waveguide. In addition to the propagation in the interior of the ocean, sound can propagate into and back out of the ocean bottom as well as scatter from the ocean surface. Just as the sound produced by a loudspeaker in a room

No single model currently exists which is adequate for all applications. This is perhaps not surprising considering the diversity of the ocean environment and its boundaries, and

Numerical Models of Underwater Acoustic Propagation, of the wave equation found in Sect.2.2.1. Fundamentally these models consider the ocean to be a deterministic environment for which the speed of sound is only a function of the spatial coordinates. Non-deterministic effects, if accounted for at all, are included in an ad hoc fashion following the d
