The American submarine would therefore have to operate with extreme caution, as nearby Russian ASW forces could be quickly launched in pursuit of the submarine if it is detected. Nikolay Burbyga and Viktor Litovkin, op. This question is very important for survivability of the CIS strategic forces at sea. If quieter American attack submarines could covertly trail them, this could cause an unstable situation in a conflict between these two countries. Several different sources all agree that the depth is 100-200 m there.
Wind generated noise is created by the action of breaking waves at the ocean's surface.
Since sound waves in the ocean are also strongly reflected by the ocean bottom, sound waves generated in shallow water are confined to very small volumes of water relative to sound waves generated in deep water. This mechanism results in markedly higher wind-generated sound power densities relative to those in deep water. In technical terms, the coherence of sound in shallow water is considerably lower than that in deep water. This means that it is not possible to achieve shallow water array gains as high as those in deep water. As a rule, in these convergence zones the correlation length of the signal is also larger.
