ABSTRACT

An analysis of surface and body bottom wave amplitude spatial distribution produced by harmonic pulsating acoustic monopole submerged in shallow water is made by approach of 3D-simulation and finite-element analysis. Wave field is investigated for homogeneous and layered bottom models by several values of ground acoustic rigidity and different depths of hydro-acoustic source submersion. The results can find an application in sea shelf seismic profiling.

Key words: sea shelf, hydro-acoustic source, surface bottom wave, finite-element analysis
