Influence of surf noise on oceanic ambient noise in coastal waters with sandy seabed

Abstract

Wave breaking almost always occurs in the surf zone of the ocean. The underwater noisegenerated by breaking waves in the surf zone is especially called the surf noise. Wilson et al. reported that the surf noise greatly contributes low-frequency oceanic ambient noise in coastal waters. The generation mechanisms of the underwater noise due to breaking waves in the surf zone were studied by Bardyshev. But the characteristic of the surf noise is not well known because of measuring difficulties. The underwater noise was measured to investigate the influence of surf noise on oceanic ambient noise in the eastern sandy coast of the middle part of the Korean Peninsula. The measurement results of ocean noise generated by breaking waves in the surf zoneare discussed. And the effect of the surf noise on the oceanic ambient noise is considered.equency oceanic ambient noise in coastal waters.
