Abstract:

Sound speed profiles from an ocean-front region are analysed to determine the magnitude and vertical scale-size of the sound-speed inhomogeneities. Order-of-magnitude estimates are made for the effects of ray diffusion on the attenuation in the sound channel and the intensity distribution near caustics. Author
