Sound Propagation Through the Stochastic Ocean.

The ocean is opaque to electromagnetic radiation and transparent to low-frequency sound. So acoustical methodologies are an important tool for sensing the undersea world. Stochastic sound-speed fluctuations in the ocean, such as those caused by internal waves, result in a progressive randomization of acoustic signals as they traverse the ocean environment. This signal randomization imposes a limit to the effectiveness of ocean acoustic remote sensing, navigation, and communication. At the same time, signal fluctuations can be used as an important probe to better understand stochastic ocean processes. Sound Propagation through the Stochastic Ocean provides a comprehensive treatment of developments in the field of statistical ocean acoustics over the last thirty-five years. This book will be of fundamental interest to oceanographers, marine biologists, geophysicists, engineers, applied mathematicians, and physicists. Key discoveries in topics such as internal waves, ray chaos, Feynman path integrals, and mode transport theory are addressed with illustrations from ocean observations. The topics are presented at an approachable level for advanced students and seasoned researchers alike.
