Stabilized Dunes on Titan indicate change in climate and surface processes

Abstract : Dune-like landforms (DLLs) have been detected at Titan's mid-to-high latitudes (which we define as the latitude band 40°-60°), similar in mor-phology to equatorial radar-dark features assumed to be dunes. DLLs have radar backscatter similar to that of surrounding materials, and we propose they are dunes that were once active but are now immobilized by more recent surface deposits.
