Have you looked at any of the Europlanet #1 abstracts that I
mentioned in another thread? Hint:
Click here.
THANKS ALEX!!!!!!
These abtracts are a goldmine......
See
http://www.cosis.net/abstracts/EPSC2006/00...3f98706a1eb74bb "VIMS cartography of Titan: cleaning out the atmosphere and constraining the surface spectrum"
This should be an extremely interesting conference and I hope some one from this group attends!!!!!!!!
And did any one note this abstract?
http://www.cosis.net/abstracts/EPSC2006/00...3f98706a1eb74bb "Regional Reflectance Change on Titan’s Surface: Implications for Atmospheric and Volcanic Activity"
Regional changes in the near-infrared reflectance of a 2800 km2 area on Titan occurred
between July 2004 and early 2006. Cassini VIMS finds that the 2 μm reflectivity
increased by a factor of two between July 2004 and March-April 2005; it then
decreased to the July 2004 reflectance by November 2005. By late December 2005 the
reflectance had surged again, slightly exceeding its earlier maximum. It then decreased
in reflectance in the three following months through mid-March 2006. The character
is inconsistent with tropospheric clouds of the type observed at Titan’s South pole and
high mid-latitudes. Application of a comprehensive radiative transfer model finds that
it is unlikely to be caused by a ground fog and most likely occurred at Titan’s surface.
This is the first direct evidence of short-term surface change on Titan. Inspection of
the spectral differences between the spot and its surrounding terrain rules out changes
in the distribution of the ices of H2O,
CO2, and CH4as the cause. Interpretations include
changing surface deposits due to abrupt tectonic or volcanic activity. This is the
first evidence for currently active tectonic processes such as volcanism on Titan."
WOW!!!!!
Looks like we will soon need to open a thread regarding regional changes on Titan ..... once we have more than abtracts to go by!
