Abstract
Akima cubic spline and spatial Fourier series (SFS) techniques for modeling ocean bottom contours from bathymetric data were comparatively analyzed. SFS methods encountered difficulty in ocean bottom reconstruction despite several enhancements to t he fundamental technique Both Akima cubic spline and SFS approaches proved unsatisfactory in reproducing first and second-order derivatives for several arbitrarily shaped ocean bottom contours. A simple reflection angle algorithm for arbitrary one-dimensional bottom models was examined and was found to be accurate. A graphical demonstration of acoustic ray interaction with the ocean bottom using a variety of mathematical ocean bottom models and the reflection angle algorithm was conducted.
