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.

Evidence for tranverse dune (or aeolian deposit) in the T21 RADAR Swath up north of Belet:



The T21 swath runs from the SW (right in the image) to the NE (left in the image)

Moving from the Belet dune fields, the dune direction slowly bends to the NE as seen in the graphic below. To the right of the image (further SW) the normal RADAR dark equatorial linear dunes are observed. Moving northeastward (to the left in the graphic), there are brightish streaks that appear to be aeolian deposits (dunes or drifts of different stuff?). These are also parallel to the equatoirial dunes.

Further to the northest (top left in the image), and indicated by purple lines, are a series of similar appearing RADAR-bright streaks that are perpindicular to the other aeolian features. These could be transverse aeolian deposits of material.

The second graphic shows a zoom of the area:



I'll speculate that the ridges (brightest areas than run EW - top left to bottom right in the image) in the T19 swath are topographically high enough to funnel the wind direction so that the drift forming wind blows primarily ENE.

AFAIK, this is one of the few regions on Titan to show transverse aeolian features. [The others are a few locations in E Belet very close to Adiri in the T8 RADAR; in the T3 RADAR swath there are a few W of Menrva that are suspect ]
