The long-term goal is understanding long range acoustic propagation in shallow water. The coherence and predictability of long-range shallow water propagation deteriorates with higher frequency and longer range of propagation. We seek to understand the randomizing effect of fluctuations in bathymetry, sound speed and the geo-acoustic properties of the bottom. Usually, a propagating sound field is randomized after tens of kilometers of transmission but occasionally, stable and coherent signals are observed at much longer range Monjo et al, 1997. We search for such islands of coherence in a sea of chaos.
