This tidal energy produces more than enough internal heat to create a global water ocean, possibly as thick in places as 50 kilometers, buried under an outer layer of ice a few kilometers thick.
«There's potentially hundreds of meters of ice, if not maybe a few kilometers, that may well be quite habitable,» Eicken says.
An international team including researchers from the Laboratoire de Planétologie Géodynamique de Nantes (CNRS / Université de Nantes / Université d'Angers), Charles University in Prague, and the Royal Observatory of Belgium [1] recently proposed a new model that reconciles different data sets and shows that the ice shell at Enceladus's south pole may be only a few kilometers thick.
A study evaluating the origins of shrubs and herbs on a group of islands in the Arctic Circle finds that seeds arrived from hundreds of kilometers away to restore plant communities lost during the last ice age — all in a matter of a few thousand years.
Images from NASA's Galileo probe a few years ago, coupled with previous observations, suggest that Europa's ice - covered surface may conceal a global, liquid ocean tens of kilometers deep.
Leaving aside the collapse of the Larsen - B ice shelf and other ice shelves in Antarctica, is it too simplistic to expect that dramatic changes should be anticipated first in the Arctic because it is sea covered by a few meters of sea ice and therefore more susceptible to change, in comparison to Antarctica (which is obviously land covered by glacial ice up to several kilometers thick in places)?
Below the ocean may be a few hundred miles (or kilometers) of a heavier form of ice that may exist under higher pressures on above a rocky core roughly 1,800 to 2,100 miles (3,000 to 3,400 km (more from Cassini news release; Lorenz et al, Science, March 21, 2008; Richard A.

There is no reason whatsoever to expect that similar behavior will be seen at the different poles; a few feet of ice floating on water is not exactly the same as two kilometers of ice piled up on a continent (East Antarctica) nor is either of those much like a kilometer of ice sitting on the sea floor (West Antarctica).
The northern melting will likely add to sea level rise explains lead author, Shfaqat Abbas Khan: «If this activity in northwest Greenland continues and really accelerates some of the major glaciers in the area — like the Humboldt Glacier and the Peterman Glacier — Greenland's total ice loss could easily be increased by an additional 50 to 100 cubic kilometers (12 to 24 cubic miles) within a few years.»
During that break - up, 3,200 square kilometers (1,235 square miles) of ice disintegrated within a few days «due to mechanical instabilities of the ice masses triggered by climate warming,» according to the European Space Agency.
