My main objective is to disseminate the results of fifty years research on ocean acoustic WPRM Wave Propagation in Random Media, have involved simultaneous measurements in space and time of all of the relevant oceanographic processes with measurements of the fluctuations of sound at Torpedo and Sonar frequencies caused by those oceanographic perturbations, in a few focused manuscripts. This research is significant to any studies where the statistics of Sonar or Torpedo frequencies are investigated. This research provides to the ocean acoustic community clear results on when the variance of the phase and amplitude of signals propagating in the random ocean can be predicted and when and why they cannot be predicted. It points out the fallacy of using second moments as predictors when the probability distributions are always extremely high tailed, i.e. the moments above 2 are non-zero. This research in the field of ocean wave propagation in random media, including developing an understanding of the spectral and correlative behavior of signals, the pdf of intensity and the invention of the CAMDMF can be transitioned to the Navy signal processing community.
