UNDERWATER ACOUSTICS
In2001theOfficeofNavalResearchbeganaprogramtopublishaselectedmono-
graph series in the field of underwater acoustics. The series publishes in-depth
reviewsandanalysisonthestateofunderstandingofthephysicsofsoundinselected
areasofresearch.
Themonographseriescoversthemostimportanttopicsinunderwatersoundinan
in-depth, critical, scholarly, and comprehensive fashion. It is intended to provide
researchers with an understanding of the physics of underwater sound, based on
both theory and experiment. The discussion of important unanswered questions is
encouraged.Topicsofparticularimportanceinthefieldarelow-frequencysoundin
thedeepocean,shallow-wateracoustics,andambientnoise.

For over 60 years, the US Office of Naval Research (ONR) has been a major
sponsorofundersearesearchanddevelopmentatuniversities,nationallaboratories,
andindustrialorganizations.AppropriatelyONRisthesponsorofthismonograph

has escalated in importance and spread broadly with richness and depth of under-
standing. It has also, quite naturally, become more specialized. The goal of this
series is to present monographs that critically review both past and recent accom-
plishments in order to address the shortcomings in present understanding. In this
way, these works will bridge the gaps in understanding among the specialists and
favorably color the direction of new research and development. Each monograph
isintendedtobeastand-aloneadvancedcontributiontothefield.Wetrustthatthe

Description:This book develops the theory of ocean ambient noise mechanisms and measurements, and also describes general noise characteristics and computational methods. It concisely summarizes the vast ambient noise literature using theory combined with key representative results. The air-sea boundary interact
