Book Description
In situ measurements were made of the velocity and attenuation of compressional waves and of velocities of Stoneley waves (from which shear-wave velocities were computed) at six stations in the sea floor off San Diego, California. Water depths ranged from 20 to 1130 meters, and sediment types ranged from medium sand to clayey silt. Sediment densities, porosities, and grain sizes were measured in samples taken at each station. The unique data obtained allowed tentative evaluations of models and equations, and computation of constants, for elastic and viscoelastic saturated, porous media. (Author).

Book Description
Rifting and Sediments in the Red Sea and Arabian Gulf Regions is a unique text that covers a wide range of topics related to the tectonics and geology of the Red Sea and Arabian (Persian) Gulf region. This book is a collection of invited and peer-reviewed chapters contributed by active researchers around the world. The topics covered in this book include tectonics, magmatism, and lithology, particularly in the Red Sea area. The book also delves into the sediments and evaporites of the Red Sea and Gulf. As the area around the Arabian Peninsula is prone to earthquakes, the seismic hazard estimated in the Red Sea region is also covered by several chapters. Each chapter presents new data and offers extensive lists of references for the reader to explore further. With the ongoing debates regarding the structure of the Red Sea, this book serves as an excellent resource for researchers and any individuals interested in the geology of these two unique seas.

Book Description
Acoustic relaxation theory for visco-elastic media provides for sound propagation in unconsolidated marine sediments. For the frequency range of 14 to 200 kHz, dispersion for compressional-wave and shear-wave velocity is negligible for all practical purposes, but sound absorption shows significant changes.

Book Description
The general objectives of this investigation were to determine and study those characteristics of the sea floor that affect sound propagation and the prediction of sonar performance; to support underwater acoustics' experiments and theory by furnishing information on the mass physical properties of sediments and rocks in the form of geoacoustic models of the sea floor; and to develop models of the sea floor which include gradients of sound velocity and attenuation, density, and elastic properties. Specifically, the minor objectives were to revise and review earlier work on the relations between frequency and attenuation of compressional (sound) waves in marine sediments and on the relations between attenuation and sediment porosity. The major objectives were to determine and predict variations of the attenuation of sound waves with depth in the sea floor.
