The developments in the field of ocean acoustics over recent years make this book an important reference for specialists in acoustics, oceanography, marine biology, and related fields. Fundamentals of Acoustical Oceanography also encourages a new generation of scientists, engineers, and entrepreneurs to apply the modern methods of acoustical physics to probe the unknown sea. The book is an authoritative, modern text with examples and exercises. It contains techniques to solve the direct problems, solutions of inverse problems, and an extensive bibliography from the earliest use of sound in the sea to present references.
Written by internationally recognized scientists, the book provides background to measure ocean parameters and processes, find life and objects in the sea, communicate underwater, and survey the boundaries of the sea. Fundamentals of Acoustical Oceanography explains principles of underwater sound propagation, and describes how both actively probing sonars and passively listening hydrophones can reveal what the eye cannot see over vast ranges of the turbid ocean. This book demonstrates how to use acoustical remote sensing, variations in sound transmission, in situ<$> acoustical measurements, and computer and laboratory models to identify the physical and biological parameters and processes in the sea.

The present book represents an outstanding text and reference for a very broad audience of senior undergraduate and graduate students, researchers, and practitioners, who are involved in the field of underwater sound--its physical background, today's engineering applications, and its modern important related areas of oceanography, remote sensing, biological characteristics, underwater communications.
The internationally renowned authors, Medwin and Clay, have produced a work that reflects the tremendous development in the field over the past two decades, and importantly, addresses it in the broadest possible way, emphasizing its current highly interdisciplinary nature.
The reader is given various techniques to solve not merely the "direct problem," for example, to predict the propagation of sound from an essential knowledge of the physical and biological data along the ocean propagation path; but also to find solutions to "inverse problems," whereby the vagaries of underwater sound propagation are used to measure the physical characteristics of the ocean and its boundaries-and sense its fish and zooplankton inhabitants.
The book's modern, authoritative nature, its breadth of coverage, and its extensive bibliography-from the earliest use of sound in the sea to present references-make it a unique source for today's acousticians, ocean engineers, physical oceanographers, marine biologists, and for every other individual who wishes to use acoustics to learn more about their fields.
Both authors are applied physicists with international reputations. In their research and teaching, they have both defined the newfield of acoustical oceanography. In 1977 a text they co-wrote, Acoustical Oceanography, was published. Herman Medwin is the former president of the Acoustical Society of America (1992-1993) and a past chair of the ASA Technical Council (1987-1988). A former chairman of the Technical Committee on Underwater Acoustics of the ASA (1975-1977), which dealt principally with naval acoustics, Medwin founded the nonmilitary Technical Committee on Acoustical Oceanography of the ASA and became its first chair (1989-1991). Medwin received his M.S. in Applied Physics from UCLA in 1948, and his Ph.D. in Physics from UCLA in 1954. He has published approximately 100 professional journal articles, and has been granted five U.S. patents with one pending.
Clarence S. Clay's scholarship in wave propagation, oceanography, and bioacoustics was recognized with a Silver Medal in Acoustical Oceanography (1993). Clay received graduate degrees in physics at Kansas State University (M.S., 1948) and the University of Wisconsin (Ph.D., 1951), where his research was in atomic spectroscopy. His publications include Ocean Acoustics and Elementary Exploration Seismology.
