Noise sources in the ocean - part 2

Abstract

Following a brief historical survey of the development of our knowledge of the origins and characteristics of ambient noise in the ocean, the principal known sources of noise are described. These are: environmental origin, biological origin and man-made. The combination of these sources leads to the modified Knudsen curves which are variable both in time and space. Methods of measurementl of noise are reviewed. A state-of-the-art tabulation of the geographic, frequency and time dependence of various sources of noise is presented as a starting point for discussion. The text is in two parts, of which this is the second
