Estimates of the basal roughness of the Antarctis ice sheet in Dronning Maud Land and its implications
Characteristics of bed topographies play an essential role for the understanding of ice sheet proc- esses. This study uses more than 120,000 km of ice-penetrating radar datasets to calculate the along track roughness of sub-glacial Dronning Maud and Coats Land. A Fast Fourier Transforma- tion (FFT)...

Summary: | Characteristics of bed topographies play an essential role for the understanding of ice sheet proc- esses. This study uses more than 120,000 km of ice-penetrating radar datasets to calculate the along track roughness of sub-glacial Dronning Maud and Coats Land. A Fast Fourier Transforma- tion (FFT) is applied to translate radar derived bed elevations into frequency domains. Thereby, two different roughness coefficients are calculated. A single-parameter roughness ( |
