A Look at Remote Sensing of the Ocean Temperature Structure.

Abstract

The problem of remotely sensing the ocean temperature structure using acoustic signalling techniques is examined. Specific attention is given to the use of geometric dispersion in determining the modal construction of the acoustic field. This analysis results in plots of modal intensity vs. time and frequency. It is shown that, except in some specific simple cases, the large number of modes present and their close spacing in these dispersion plots require a resolution which is unattainable at this time. However groups of modes of relatively high intensity form patterns in these dispersion plots and should be resolvable. A straightforward comparison of measurements and theory should provide a method of remotely sensing the ocean temperature structure. This method requires experimental verification. (Author)
