Ruth Simpson,Jason Hughes,Natasha Slutskayaindicate the following: the wave speeds show very weak, logarithmic frequency dispersion; the attenuations are closely proportional to frequency, f; and both wave speeds increase with increasing mean grain size. A new theoretical approach to wave propagation in unconsolidated sediments is described,

Acoustic propagation is sensitive to certain acoustic properties including the reflection coefficient at the water-sediment interface, and the sound speed and attenuation profiles within the sediment interior. To be generally useful, the models must be capable of

The Power of Class; the Gender of Power,s, for shallow water environment studies. In particular, we show here that the joint inversion of direct, reflected and head waves provides a better reconstruction of the sea water, the shallowest Earth layers and their inhomogeneities in depth. It doubles in fact the available ray paths and travelt

The main features of the buoys are the large dynamic range, digital signal conditioning unit, global positioning system receiver and reliable radio data link. The buoys drift away from a broadband source receiving its pings at known positions. Single hydrophone, matched
