Book excerpt: Les ondes sonores constituent le seul moyen d'investigation et de transmission à grande distance utilisable en pratique dans le milieu marin. Apparue au début du XXe siècle, l'acoustique sous-marine est devenue une des technologies essentielles utilisées pour l'exploration et l'exploitation des océans à des fins scientifiques, industrielles ou militaires. Elle peut prétendre jouer aujourd'hui dans l'océan le même rôle que les ondes radio et radar dans l'atmosphère et dans l'espace, et est largement employée dans les domaines de la navigation, de la pêche, de la défense, de l'océanographie et de l'ingénierie marine. Cet ouvrage présente de manière claire et synthétique les phénomènes physiques fondamentaux régissant les ondes acoustiques sous-marines, les principes de fonctionnement des systèmes sonar, et un panorama de leurs applications.

Available in PDF, EPUB and Kindle. Book excerpt: This book provides an up-to-date introduction to the theory of sound propagation in the ocean. The text treats both ray and wave propagation and pays considerable attention to stochastic problems such as the scattering of sound at rough surfaces and random inhomogeneities. An introductory chapter that discusses the basic experimental data complements the following theoretical chapters. New material has been added throughout for this third edition. New topics covered include: - inter-thermocline lenses and their effect on sound fields - weakly divergent bundles of rays - ocean acoustic tomography - coupled modes - sound scattering by anisotropic volume inhomogeneities with fractal spectra - Voronovich's approach to sound scattering from the rough sea surface. In addition, the list of references has been brought up to date and the latest experimental data have been included.

Book excerpt: Le marin a toujours été confronté à deux problèmes : connaître la hauteur d'eau sous la quille et naviguer en sécurité par temps de brume. On découvrira ici comment, en recourant à la transmission du son par l'eau, les scientifiques trouvèrent une solution : elle se concrétisa, en 1905, par la construction du premier sondeur acoustique. Peu de temps après, le naufrage du Titanic puis la menace des sous-marins pendant la première Guerre mondiale provoquèrent un afflux d'inventions, dont celle du grand physicien Paul Langevin (1872-1946) ; en recourant aux ultrasons, il fonda l'acoustique sous-marine moderne. C'est ainsi que les responsables de la marine militaire comme de la marine marchande firent appel aux chercheurs appartenant aux domaines les plus pointus de la physique. L'ouvrage dévoile à cette occasion comment ce contexte scientifique était alors dominé par les conflits entre nations autant que par des enjeux économiques. Devenues de plus en plus efficaces, les machines permettent aujourd'hui de mieux connaître la planète bleue. La dernière partie de l'ouvrage évoque la rançon de ce succès : une menace pèse sur les cétacés qui doivent désormais partager avec l'homme le domaine des ondes acoustiques.
