Abstract : Analysis of ocean ambient-noise samples indicated that such noise, under certain conditions, can be assumed to have a gaussian distribution of amplitudes. Similar tests showed that ship-noise samples are not gaussian. In the analytical procedure, the method of moments was found to be the most suitable for providing accurate and useful estimates of the parameters. (Author)
