All...

the latest CHARM presentation details the longitudunal dunes on Titan.

http://saturn.jpl.nasa.gov/multimedia/prod...HARM_Lorenz.pdf

Slide 4 shows that Titan albedo features are buried in the old Voyager data. Neat.
Slides 11 is a great reprojection of DISR.
Several slides with great Earth SIR-C and CASSINI Titan dune comparisons.
Slide 41 shows a section of T21 with dunes that I do not believe has been released as yet.
Slide 42 dune orientations....
Slide 44 showing calculated paths for Titan balloon probes (data taken fron the dune orientations acting as weather vanes).

Very cool...

Doug.... I was not sure which Titan thread to place this in so I created one. Move it where it makes sense.

The graphic above shows an area near a RADAR bright area where the dune field is also different than expected. This is in an areas directly S of the W Quivira Evil Eye in the T25 RADAR Swath. The dunes seem to be oriented NW-SE (indicated by the dashed red zone). The dune field is more chaotic and has a smaller intedune area.

This would be consistent with an area where the NE component of the wind vector is overexpressed. So it could be an area that is oriented SW-NE and is a downwind depression or drop. (The drop acting as a windshadow for the SE wind vector component). This could be an extension of the bright islands, with an "undermud" third island obsurced by the sands, but evidenced by it's wind shadow effect.

(Also note how the most SW bright island in this image seems lower than the bright island to it's NW. It has a lower downwind mantle and the dune lines seem unpreturbed passing over it. This could be a series of three islands slowly getting lower as they drop to the SW, with the most SW lying under the dark smooth muds.)
