Many marine mammals communicate by emitting sounds that pass through water. In the past few decades the oceans have become increasingly noisy, as underwater sounds from human activities make it difficult for marine mamals to communicate. This book discusses how well marine mammals hear, how noisy the oceans have become, and what effects these new sounds have on marine mammals.
Preface. Introduction. Acoustic Concepts and Terminology. Measurement Procedures. Sound Propagation. Ambient Noise. Man-Made Noise. Marine Mammal Sounds. Marine Mammal Hearing. Documented Disturbance Reactions. Zones of Noise Influence. Significance of Responses and Noise Impacts. Conclusions and Data Needs. Literature Cited. Appendices: Common and Scientific Names of Marine Mammals. Acoustical Glossary. Subject Index.
Praise for the Book "the text is well written and flows quite smoothly... a valuable, detailed source book for any marine biologist, and certainly for marine mammologists, be they field researchers or agency officers and administrators. Strongly recommend." --JOURNAL OF EXPERIMENTAL MARINE BIOLOGY AND ECOLOGY, 1997 "...provides a comprehensive review of the effects of man-made noise on marine mammals... very timely given the growing interest and concern about underwater noise as a form of habitat degradation in the marine environment. I strongly recommend this book for anyone interested in bioacoustics, marine biology, or the conservation of marine animals. It will be the standard reference for a large body of literature..." --ANIMAL BEHAVIOUR, 1997 "A very readable text and specific topics are quite easy to locate...The authors are to be congratulated for the depth of their research and particularly for the clarity and objectivity of their presentation of what is a technically complex, sometimes emotive and frequently misinterpreted subject area... Thoroughly recommended reading and an excellent reference." --David Goodson, Loughborough University, in AQUATIC MAMMALS
