Sand Sea Extents And Sediment Volumes On Titan From Dune Parameters, Karl D. Arnold
Sand Sea Extents And Sediment Volumes On Titan From Dune Parameters, Karl D. Arnold
Theses and Dissertations
Linear dunes are one of the most abundant and important features on the surface of Titan. We present a model for estimating the volume of dune sediment using the area coverage of Titan's sand seas along with dune widths, spacings, and heights. This helps to reveal local sediment transport and deposition. We refine global dune area estimates from Cassini SAR (Synthetic Aperture RADAR) of 20 million km2 or 24 ± 3% of Titan's surface based on ~50% Cassini RADAR global coverage. Additionally, the global area of sand seas is estimated from a joint analysis of Cassini SAR and ISS (Imaging …
