We list several applications of underwater acoustics and discuss underwater sound propagation in the framework of ray theory. The concept of ray chaos is introduced. It is shown that Poincaré sections and Lyapunov exponents provide equivalent descriptions of simple environmental models. We consider a class of environments not previously studied - those where there are transitions between single- and double duct sound speed versus depth profiles. To examine the behaviour of propagation in transition regions the concept of launching basins is introduced, and its use in the design of system performance is indicated.
