P.F. Worcester, in Encyclopedia of Ocean Sciences (Second Edition), Introduction. Ocean acoustic tomography is a method for acoustic remote sensing of the ocean interior that takes advantage of the facts that the propagation of sound through the ocean is sensitive to quantities of oceanographic interest, such as temperature and water velocity, and that the ocean is . Ocean variability effects on sound propagation in shallow water Abstract: In May SACLANT Undersea Research Centre conducted an experiment south of the Island of Elba off the west cost of Italy to investigate the time variability of received broadband acoustic signals over a km fixed propagation path for 36 h. Following an introduction on ocean variability, acoustic propagation, and coupled models, subsequent chapters present up-to-date coverage of the developing relationship between ocean science and ocean acoustics, including an extensive . Following an introduction on ocean variability, acoustic propagation, and coupled models, subsequent chapters present up-to-date coverage of the developing relationship between ocean science and ocean acoustics, including an extensive review of state-of-the-art three-dimensional models. show more.
Variability, Coherence and Predictability of Shallow Water Acoustic Propagation in the Straits of Florida H. A. Deferrari, N. J. Williams, H. B. Nguyen Pages Be that as it may, with modern ocean acoustic observation capability, vast improvement to the AFAR and MATE results could be obtained and provide definitive tests for many of our ideas about ocean acoustic propagation. The concluding remarks from Chapter 1 of the book summarize the state of affairs, as there is a lot of work still to be done. Sound propagation in the ocean is governed by the spatial structure of the sound speed and the sound speed in the ocean is a function of temperature, salinity, and ambient pressure. Since the ambient pressure is a function of depth, it is customary to express the sound speed (c) in meters per second as an empirical function of temperature (T) in degrees celsius, salinity (S) in parts . Introduction to Propagation: Introduction to acoustic propagation theory and modeling in the ocean environment including selected experimental results and comparison to theory. Various propagation theories and examples will be discussed including ray theory, mode theory, and the parabolic equation. modeling effects of ocean variability on.
