Sound Attenuation in Marine Sediments

Résumé du livre

In situ measurements of compressional (sound) velocity and attenuation were made in the sea floor off San Diego in water depths between 4 and 1100 m; frequencies were between 3.5 and 100 kHz. Sediment types ranged from coarse sand to clayey silt. These measurements, and others from the literature, allowed analyses of the relationship between attenuation and frequency, relationships between attenuation and other physical properties, and study of appropriate viscoelastic models which can be applied to saturated sediments. Some conclusions are discussed. (Author).
