EXAMINATION OF MULTIPATH PROCESSES IN A RANGE DEPENDENT OCEAN ENVIRONMENT WITHIN THE CONTEXT OF ADIABATIC MODE THEORY

An extension of the work by Tindle and Guthrie, allowing extraction of ray path information within the context of adiabatic mode theory, has been carried out. The purpose of this extension is to examine the adiabatic solution with respect to the process of multipath conversion due to a sloping bottom. Examples are given which compare ray traces performed by conventional means and ones performed within the context of adiabatic mode theory for upslope propagation in an isovelocity, wedge shaped ocean. The agreement is seen to be quite good even up to bottom slopes as high as 10°. © 1979, Acoustical Society of America. All rights reserved.
