Abstract

3D numerical simulation of hydro and seismic waves generated by acoustic monopole submerged in shallow water for seismic profiling of bottom medium is demonstrated. Peculiarities of hydroacoustic waves in the water, seismic field configuration in the bottom interior and fluid-solid interface are presented at several frequencies of the bound 100-200Hz. Сapability of remote diagnostics of the subsurface layers lying immediately under the bottom is analyzed. The diagnostic signs are found in the features of amplitude spatial relief formatting with surface wave on fluid-solid interface.
