Abstract

The report examines the propagation of a sound field from a point source down the slope in the area of the coastal wedge of the ocean in the presence of a sound speed profile (thermocline). It is shown that the presence of the thermocline leads to the appearance of local areas of strong mode coupling and, accordingly, to specific spatial variability of the sound field. The theory and results of modeling the variability of the sound field in a wedge on the basis of the parabolic equation and adiabatic mode theory are presented.
