Titan's Dunes by the Numbers

Abstract : Thousands of dunes observed on the surface of Saturn's moon Titan were one of the greatest surprises uncovered by the Cassini spacecraft [1]. Dunes point to the mobility and processing of sediments on Titan - they are the telltale signatures of wind at work. As such, they provide crucial insights into the geology and climatic history of Titan. Being likely mainly composed of solid organics, they also hold clues on the methane and carbon cycles on Titan. In this paper, we will put numbers on dune areal coverage, volume, altitude and latitude distribution and show how these numbers can help understand past and present conditions on Titan.
