Two-Dimensional Internal Wave Spectra

Abstract

The theme of this conference is oceanic acoustic modelling. As has just been demonstrated (Munk, 1975; Flatte, 1975), oceanic internal wavescan produce significant modifications to the propagation of sound. Of necessity , an acoustic model must simplify the structure of the ocean, if for no other reason than the fact that a deterministic description of the ocean is beyond the realm of possibility--the ocean is too large and its motions are too complicated. Thanks to Garrett and Munk (1972, 1975), we now have a viable internal wave model. The Garrett and Munk models are two-dimensional models of oceanic density spectra constructed from essentially one-dimensional data. The aim of this talk is to report results of a two-dimensional wave spectrum obtained from measurements in the ocean and to relate this two-dimensional spectrum to a Garrett-Munk type model.
