An asymmetric distribution of lakes on Titan as a possible consequence of orbital forcing

Lorenz, R. D.; Lunine, J. I.; Hayes, A. G. +3 more

A set of lakes filled or partially filled with liquid hydrocarbon and empty lake basins have been discovered in the high latitudes of Saturn's moon Titan. These features were mapped by the radar instrument on the Cassini orbiter. Here we quantify the distribution of the lakes and basins, and show a pronounced hemispheric asymmetry in their occurre…

Multiple origins of linear dunes on Earth and Titan

Rubin, David M.; Hesp, Patrick A.

Dunes with relatively long and parallel crests are classified as linear dunes. On Earth, they form in at least two environmental settings: where winds of bimodal direction blow across loose sand, and also where single-direction winds blow over sediment that is locally stabilized, be it through vegetation, sediment cohesion or topographic shelter f…
