Abstract : The objective of this work was to develop a general theoretical frame work for calculating fluctuations of signals on waves propagated through random media (WPRM) and to apply this framework to sound through the ocean. Comparison with real data is an important aspect of the effort. We have made quantitative and reliable our ability to calculate the effects of internal waves on oceanic sound transmission, over a wide range of parameters. Ranges may vary from a few hundred meters to thousands of kilometers, while frequencies from 50 Hertz to 100 kHz can be treated.
