The Seamount as a Diffracting Body

Abstract

Diffraction over a seamount has been studied by construction of a three-dimensional physical model of Dickens seamount. When laboratory diffraction and scattering data for air are scaled to the ocean and added to ray refraction losses at sea there is excellent agreement with ocean experiments reported by Ebbeson et al <J. Acoust. Soc. Am. 64, S76 (1978)>.
