The Measurement of Underwater Noise Characteristics in Shallow Waterrements were accomplished with two hydroacoustic antennas. One of them was placed near the coast and the other on the shelf edge. The parameters studied were the spectral-energetical and correlational characteristics of noise fields. The primary noise source in the near-coast location was the surf,

The Investigation of Underwater Noise Sources by Emission Acoustic Tomographyraphy proposed by Munk, the emission acoustic tomography is based on the dependence of the characteristics of the ambient sea noise field on the spatial distribution of noise sources and allows its reconstruction. Equations relating the system to the spatial distribution of sources are presented. Al

Ambient Sound as a Probe of Ocean Surface Processes its generation. This is especially true of ocean surface processes such as wave-breaking and bubble production. New types of instrumentation are yielding measurements of the frequency distribution of radiated sound, its temporal variability and its spatial pattern. These observations tend to suppor

The Properties of the Vertical and Horizontal Power Flows of the Underwater Ambient Noised which depend on depth and wind speed; the phenomenon of the suppression of the vertical noise power flow by the local source field is also described..It is shown that coherence of this vertical flow of acoustical power degrades with increasing depth while coherence of the horizontal flow grows and

Low frequency noise measurements in an ambient environment dominated by natural sources of soundal physical sources of underwater sound. The New Zealand area is notable for its low shipping density. This enables the contribution and effect of natural sources on ambient noise levels in the frequency band below 250Hz to be more fully explored..The effect of wind speed on low frequency ambient no
