Seismic Studies of the Geologic Structure and Physical Properties of the Seabed.

摘要

To determine the physical parameters that most affect low frequency acoustic propagation in shallow water areas where elastic and acoustics waves interact intimately. To develop instrumentation, field procedures and data inversion methods for accurate measurement of shear wave speed and attenuation as functions of frequency, depth, and locations in the seabed, and to determine the effects of anisotropy and other inhomogeneities created by sedimentary processes.
