Shallow Water Acoustics
Boris G. Katsnelson and Valery G. Petnikov
Shallow-water acoustics (SWA) is a tool used by physicists,
geophysicists, geologists and oceanographers for continental shelf monitoring; acoustic techniques play a decisive role in detecting seabottom materials and natural resources such as oil, fish and sea animals, and they also have military applications.
From eight special expeditions on the Russian shelf zone in the Barant
Sea and the Black Sea, the authors have accumulated over 15 years of
research data in ocean acoustics. In this unique and specialist text, they detail the main theoretical approaches and models of SWA together with various experimental results, focusing primarily on the physical results describing the sound field in wave length. Dynamic phenomena (tides, internal waves) are considered from an acoustical perspective, as is the scattering of sound over the macroscopic body in shallow water waveguide.
This book is a translation into the English language of the monograph Akustika Melkogo Morya published in Russia by Nauka in 1997. The first edition was produced with financial support from the Russian Foundation for Basic Research (RFBR) (project 96-02-30051). In preparing the English edition we have extended the content of the book somewhat, adding to it two sections which are important for shallow-water acoustics. These relate to acoustic noise and the diffraction of acoustic waves on localised anomalies in shallow-water sound channel. It is also important to note that since the publication of the first Russian edition of the book interest in shallow-water acoustics has increased even more. This is evidenced by the succession of acoustic experiments carried out on the sea shelf in recent years, for example, the SWARM (Shallow Water Acoustics Random Media) experiment (Headrick et al. (2000)). To our great regret, we have not been able to give these experimental results the coverage they deserve, but we hope that this book will prove useful for their interpretation and in the design and execution of future studies on the sea shelf.
