<P>This book is a research monograph on high-Frequency Seafloor Acoustics. It is the first book in a new series sponsored by the Office of Naval Research on the latest research in underwater acoustics. It provides a critical evaluation of the data and models pertaining to high-frequency acoustic interaction with the seafloor, which will be of interest to researchers in underwater acoustics and to developers of sonars. Models and data are presented so as to be readily usable, backed up by extensive explanation. Much of the data is new, and the discussion in on two levels: concise descriptions in the main text backed up by extensive technical appendices.</P>
This book is a research monograph on high-Frequency Seafloor Acoustics. It is the first book in a new series sponsored by the Office of Naval Research on the latest research in underwater acoustics.
The efficacy of sound to penetrate the seas made acoustic systems in the past century the leading tools for sensing objects in and measuring properties of the seas. For over sixty years The United States Office of Naval Research (ONR) has been a major sponsor of undersea research and development at universities, national laboratories, and industrial organizations. App- priately ONR is the sponsor of this monograph series. The intent of the series is to summarize recent accomplishments in, and to outline perspectives for, underwater acoustics in specific fields of research. The general field has escalated in importance and spread broadly with ri- ness and depth of understanding. It has also, quite naturally, become more specialized. The goal of this series is to present monographs that critically review both past and recent accomplishments in order to address the sho- comings 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 is intended to be a stand-alone advanced contribution to the field. We trust that the reader will also find that each is a critical introduction to related specialized topics of interest as well.
Basic Concepts and Definitions.- The Nature of Marine Sediments.- Physical Properties.- Geoacoustic Properties.- Seafloor Roughness.- Sediment Heterogeneity.- Fluid Theories.- Elastic Theories.- Poroelastic Theories.- Reflection.- Seafloor Scattering Experiments.- Roughness Scattering Models.- Sediment Volume Scattering.- Acoustic Penetration of the Seafloor.- Backscatter Statistics.
<P><EM>High-Frequency Seafloor Acoustics</EM> is the first book in a new series sponsored <BR>by the Office of Naval Research on the latest research in underwater acoustics. <BR>This exciting new title provides ready access to experimental data, theory, and <BR>models relevant to high-frequency seafloor acoustics and will be of interest to <BR>sonar engineers and researchers working in underwater acoustics. The physical <BR>characteristics of the seafloor affecting acoustic propagation and scattering are <BR>covered, including physical and geoacoustic properties and surface roughness. <BR>Current theories for acoustic propagation in sediments are presented along <BR>with corresponding models for reflection, scattering, and seafloor penetration.&nbsp; <BR>The main text is backed up by an extensive bibliography and technical appendices. </P>

It provides a critical evaluation of the data and models pertaining to high-frequency acoustic interaction with the seafloor, which will be of interest to researchers in underwater acoustics and to developers of commercial and military sonars. Models and data are presented so as to be readily usable, backed up by extensive explanation. Much of the data is new, and the discussion in on two levels: concise descriptions in the main text backed up by extensive technical appendices. This monograph will provide ready access to data and current models and a clear path through a somewhat confusing literature. There is an extensive bibliography, and the main text points towards the essential literature.</P>
