A Review of the Statistical Properties of the Ocean Surface.
Abstract
This study reviews the work on ocean surface statistics and some new approaches are considered. A brief discussion of some similarities between ocean surface statistics and underwater sound noise fields is included. The author outlines the method for obtaining the equation showing the relation between the spatial-temporal correlation and the directional wave spectrum. Methods of measuring the spatial-temporal correlation of the surface are mentioned along with the equations, and special cases of this correlation are considered. The most important one (i.e. the simplest to measure) is the temporal correlation at a point on the surface. The Fourier Transform of this correlation leads to the power spectrum of the Neumann-Pierson type. Finally, a method of obtaining cross spectra between pairs of a linear array of elements is discussed and similarities between this method and the underwater sound problem of obtaining the directionality of ambient noise is mentioned.
