Transverse aeolian ridges on Mars: First results from HiRISE images
Abstract
Three images obtained by the High Resolution Imaging Science Experiment (HiRISE) were analyzed for the information they could provide regarding Transverse Aeolian Ridges (TARs) on Mars. TARs from five locations in a HiRISE image of the floor of Ius Chasma show remarkably symmetric (cross-sectional) profiles, with average slopes for the entire feature of ~ 15°; these results apply to TARs that span an order of magnitude in wavelength and a factor of 6 in height. A HiRISE image of Gamboa impact crater in the northern lowlands shows low albedo sand patches = 1 m, and a granule ripple origin for TAR-like ripples with heights <= 0.5 m.
