Multiple Scattering of Sound by Internal Waves and Acoustic Characterization of Internal Wave Fields in Deep and Shallow Water

Abstract

LONG-TERM GOALS * To improve understanding of the effects of internal waves (IWs) on sound propagation underwater. * To develop an empirical statistical description of IWs in shallow water. * To measure acoustically path-averaged energy of IWs in the ocean and variations of the energy on time scales from hours to years. * To develop a comprehensive model of the IW spectra in the deep ocean and their regional and temporal variability.
