Default Radical! Liquid Water on Enceladus

The NASA Cassini-Huygens press release -
http://saturn.jpl.nasa.gov/news/pres...cfm?newsID=639
- implies it is coming out of the hole at least 32 degs F, since the
water is in a liquid state.

Actual surface temperature measurements -
http://saturn.jpl.nasa.gov/multimedi...m?imageID=2028
- indicate about a 100 deg F temperature change across in "narrow zones
a few hundred meters wide along" Enceladus fissures - raising the area
temperature to a balmy 145 Kelvin or -199 deg F.

The C-H fissure model speculates that the water -
http://saturn.jpl.nasa.gov/multimedi...m?imageID=2026
- is pressured and cooled in sub-surface pockets at about 31 deg F.
This is similar to the water in Lake Vostok trapped under the Anarctic
ice cap were heat from the planet's plate keeps the water from
freezing.

What I didn't see in the press release was whether the spectrometer
picked up any other elements in the geysers that would indicate
volcanic contaminents. No volcanic elements, IMHO would seem to imply
some kind of subsurface water body.

If there are no volcanic contaminents, what other cause could there be?

P.S. -

"Enceladus may have cold resistant sea monkeys living in
its alleged liquid oceans"


And more importantly, do these cold resistant sea monkeys build
telescopes with lenses made of ice? -
