Sand transport map. Notional sand transport map with VIMS R=5μm, G=2μm, B=1.3μm of Titan’s equatorial region in cylindrical projection. The annotations on the map show that each major sand sea or dune field has sand corridors from the west from which new sand can arrive and sand corridors to the east for it to exit. Two possible exceptions are indicated as pink ‘x’s: small dunefields within Adiri and some east of Yalaing Terra. The major obstacle to global sand transport then is Xanadu, for which we propose two possible mechanisms for the sand to bridge the gap (see text), fast-moving barchan dunes and fluvial sediment transport in river channels. These particular sand transport corridors are hypothetical, though consistent with both topography [59] and observed sand transport directions [3].
