Significant horizontal inhomogeneities of the noise field in the ocean

Horizontal inhomogeneities of the ocean medium lead to horizontal inhomogeneities of the noise field. We looked at the inhomogeneities caused by the cold eddies and ocean bottom’s break ups. In addition noise sources on the ocean surface are considered to be horizontally homogeneous. Thus, effects connected with specifics of noise propagation in the complex ocean medium are analyzed. Radiation transfer theory is used successively for noise fields calculation. It is considered that the noise is more prominent in the water waves lines and almost absent in the waves lines reflected from the ocean bottom (ground wave lines).
