Sound Images of the Ocean

Ocean acoustics comprises a key subfield of research, providing indispensable tools for the exploration of the seafloor, other underwater formations and processes. Sound Images of the Ocean employs 400 sound images, contributed by 120 author/marine experts from 22 nations, to create a comprehensive overview of acoustic imaging applications in the sea. This remarkable ensemble spans fields of geophysical research, off-shore industrial and economic activities, national surveillance, and protection of the ocean and continental shelves. Written to be accessible to professionals in diverse related fields, the concise accompanying explanations of the complex relationships revealed by the images strive to condense the results into the essential "message." For readers, this remarkable atlas develops an interdisciplinary understanding of underwater acoustics and its diagnostic capabilities to visualize in detail the two thirds of the surface of the globe otherwise hidden from view.

Résumé

Sound Images of the Ocean is the first book of its kind which offers a comprehensive overview of acoustic imaging applications in the various fields of marine research, utilization, surveillance, and protection. The book employs 400 sound images of the sea floor and of processes in the sea volume, contributed by more than 120 marine experts from 22 nations. Written to be accessible to professionals in diverse related fields, the concise accompanying explanations of the complex relationships revealed by the images strive to condense the results to an essential "message." The book develops an interdisciplinary understanding of underwater acoustics and its diagnostic capabilities in order to visualize in detail the two thirds of the surface of the globe otherwise hidden from view. The high resolution but ship dependent acoustic imagery is compared with its satellite dependent counterpart, the large scale sea floor imagery by scanning the gravity deformed sea surface.
