The North Pacific Acoustic Laboratory (NPAL) program is intended to improve our understanding of (i) the basic physics of low-frequency, broadband propagation in deep water, including the effects of oceanographic variability on signal stability and coherence, (ii) the structure of the ambient noise field in deep water at low frequencies, and (iii) the extent to which acoustic methods, together with other measurements and coupled with ocean modeling, can yield estimates of the time-evolving ocean state useful for acoustic predictions. The goal is to determine the fundamental limits to signal processing in deep water imposed by ocean processes, enabling advanced signal processing techniques to capitalize on the three-dimensional character of the sound and noise fields. OBJECTIVES A series of deep-water acoustic propagation experiments combining low-frequency, broadband sources with vertical and horizontal receiving arrays were conducted in the North Pacific Ocean during the period 1989 to 2005 as part of what is loosely referred to as the North Pacific Acoustic Laboratory Report Documentation Page Form Approved OMB No. 0704-0188 Public reporting burden for the collection of information is estimated to average 1 hour per response, including the time for reviewing instructions, searching existing data sources, gathering and maintaining the data needed, and completing and reviewing the collection of information.

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.
