The Seamount as a Diffracting Body
Diffraction over a seamount has been studied by experiments with a three-dimensional physical model of DICKENS seamount. When laboratory diffraction and scattering data are scaled to the ocean and added to absorption and refraction losses at sea, there is excellent agreement with ocean experiments reported by Ebbeson et al. (J. Acoust. Soc. Am. 64, S76 (1978). Both the magnitude and the frequency dependence of the shadowing at sea are predicted over a decade of frequencies.
