Characteristics of the Two-Dimensional Spectrum of Roughness on a Seamount

Abstract

Advances in bottom mapping technology, such as multibeam bathymetric survey systems, have made it possible to obtain detailed depth measurements over two horizontal dimensions and to develop statistical models that describe variability of small-scale ocean bottom roughness. This report investigates the nature of the two dimensional power spectrum of the bottom roughness of a seamount. The characteristics of the power spectra are discussed; particular emphasis is placed on the issues of anisotropy and the power law behavior of the bottom roughness.
