Abstract

Based on the theory of the local spectrum of ambient-sea noise field,theoretical models of the low-noise-channel for typical shallow-water negative gradient (or thermocline) are developed.The results show that,for the wind-related surface noise sources,the noise field at frequencies above a few hundred Hz is clearly characteristic of the low-noise-channel for above-mentioned sea-hydrographic distribution and various sea-bottom types.
