However, the discovery in 2015 of an oscillation in Enceladus's rotation known as a libration, which is linked to tidal effects, suggests that it has a global ocean and a much thinner ice shell than predicted, with a mean thickness of around 20 km.

Since a thinner ice shell retains less heat, the tidal effects caused by Saturn on the large fractures in the ice at the south pole are no longer enough to explain the strong heat flow affecting this region.

The specific distribution of fractures, either sparse or numerous, could be used to further distinguish between a thick and thin ice shell.»

If the subsea heat is intense and the ice shell is thin enough, the surface ice shell can melt directly and cause regions of what appear to be broken, rotated, and tilted ice blocks, called «chaos» terrain (Nimmo and Giese, 2004; Spaun et al, 1999 and 1998; and Greenberg et al, 1998).
