Abstract
Attempts to explain the origin of sand ridges on continental shelves require objective means for quantifying their wavelengths and orientations. Two-dimensional power spectral analysis is such an approach. However, mathematical peculiarities may lead to apparent discrepancies between the results of spectral analysis and wavelength estimates from bathymetric maps. This discrepancy may explain much of the reported difference between wavelength predictions based on hydrodynamic stability theory and measurements from bathymetric maps. Such a discrepancy can be significantly reduced by a modified spectral analysis technique which utilizes power spectra of bottom slopes rather than bathymetry.
