Topography of Moving Dunes in Nili Patera 
These dunes are active and, by computing the height of the moving dunes using this DEM, researchers have determined the sand flux (sand volume per length per time) and find that it is similar to that seen for dunes in Antarctica.  The research also finds that the dunes are moving as coherent masses of mobile sand. This work has important implications, as it shows that wind processes on Mars can transport considerable volumes of sand, which not only contributes to dune migration, but also abrasion (sand blasting) of the surface.
