    "abstract": "We investigate sound ray propagation in a range-dependent underwater acoustic\nwaveguide. Our attention is focused on sensitivity of ray dynamics to the\nvertical structure of a sound-speed perturbation induced by ocean internal\nwaves. Two models of longitudinal sound-speed variations are considered: a\nperiodic inhomogeneity and a stochastic one. It is found that vertical\noscillations of a sound-speed perturbation can affect rays in a resonant\nmanner. Such resonances give rise to chaos in certain regions of phase space.\nIt is shown that stability of steep rays, being observed in experiments, is\nconnected with suppression of resonances in the case of small-scale vertical\nsound-speed oscillations.",
