Abstract

The sound field produced by a low-frequency (100-1000 Hz) point source in a shallow water region in the presence of the temperature front is considered. It is shown that the latter anisotropic inhomogeinity leads to a substantial horizontal refraction and to a number of related effects: a redistribution of the sound field in the horizontal plane, changes in the spectral and mode contents of a pulse in the course of its propagation, and changes in the arrival times at the receiver. A theoretical analysis and a numerical modeling are carried out for the Polar Front of the Barents Sea.
