		True for all the Galilean Moons more or less. Their orbits all lie within the Jovian equivalent of the Van Allen belts. And Jupiter's magnetic field is much stronger than earth's.

Beautifully designed article. Very cool images and diagrams.

> We want rocks in contact with water,

But there is ice compressed between the water column and the xenoceanic bottom, ok. I see the problem.

What about rocks in the surface of the water?. Some volcanic rocks can float.
