The effect of sound-speed fluctuations on acoustic propagation is described with emphasis placed on the unique aspects of the ocean environment.The unsaturated region, where intensity flucutations are small, is treated by the Rytov, or supereikonal method.The saturated region, where intensity fluctuations are large, is 'treated'by micro multipath theory utilizing path integrals.The statistical inhomogeneity and anisotropy of ocean sound-speed fluctuations are specifically treated.Internal wave rather than turbulence spectra are used.The complications due to the deterministic sound channel are taken into account.
