Intensity correlations for ocean acoustic propagation show markedly different behavior in the partially saturated regime than in the fully saturated regime. In contrast to the known exponential decay of temporal intensity correlations in full saturation, partial saturation correlations fall off very slowly. This phenomenon is a consequence of the peculiar time dependence of internal waves, and does not occur in other physical situations, such as atmospheric optics. Results of a numerical simulation which demonstrate the effect are presented.
