The given lecture (mini‐tutorial) is dedicated to description of recent efforts (last 10–15 years) in experimental observation and theoretical modeling of the sound propagation in shallow water in the presence of traveling internal solitonlike waves (ISW). It contains a review of the main experimental observation of acoustical effects (Rubinstein and Rubinstein and Brill, Zhou etal., Badiey etal., etc.) The main theoretical approaches can be divided in dependence on orientation of ISW wave front: (1) Modes coupling due to ISW, traveling along acoustic track. Resonance effects in sound propagation, resonance coupling by packets and separate solitons (J‐X Zhou, Preisig and Duda, etc.) are considered. (2) Horizontal refraction (HR) caused by ISW crossing acoustic track. Technique of vertical modes and horizontal rays, vertical modes and PE in horizontal plane and modeling of acoustic effects in typical conditions of Barents sea are shown. Analysis of specific peculiarities due to HR (synchronicity, periodicity, and depth dependence of intensity fluctuations) is given. Experimental observations of acoustic effects in the SWARM’95 (broadband sound propagation, shot and LFM signals) are presented. New specific features of signals, passing through ISW space‐frequency horizontal structure, and fluctuations of modal spectrum are demonstrated, and experimental setup to register these is discussed.
