The periodic topography of ice stream beds: insights from the Fourier spectra of mega-scale glacial lineations
This paper reports the first application of the 2-dimensional discrete Fourier transform method to describing and analyzing the orientation-specific roughness elements of mega-scale glacial lineations (MSGL). Applying the technique to several case study examples reveals characteristic, orientation-specific roughness scales that guide process-related inferences on MSGL formation and evolution.
