Interiors of Ganymede and Europa

Possible locations of liquid layers in the icy moons of Jupiter are shown here as a function of depth:

completely frozen;
three-layered structures impeding any contact between the liquid layer and the silicate floor;
thick upper icy layer (>10 km) and a deep ocean;
very thin upper icy layer (3-4 km).

Cases 3 and 4 are the most probable for Europa, and cases 1 and 2 for Ganymede and Callisto.
