Description 202-212
Analytical solutions of the normal modes for acoustic wave propagation in
shallow water homogeneous ocean overlying an interacting semi-infinite solid
half space consisting of homogeneous, isotropic soil or rock are studied in
this paper. The effects of the three parameters, namely, water depth,
mechanical and acoustic properties of seabed and source frequency are studied
numerically. The penetration depth of acoustic waves below seabed due to a
source located in water column has been obtained as functions of these
parameters by extensive numerical study of the frequency equation that governs
the normal modes. For a chosen water depth and seabed properties, a cutoff
frequency estimate has been obtained such that source frequencies above it will
have almost zero depth of penetration.
