Callisto's #ionosphere alone cannot explain all existing magnetic measurements, but that a subsurface #ocean in combination with the ionosphere can.

The ocean is likely at least tens of kilometers thick, as measured from the top of the liquid ocean to its seafloor, and encased beneath a solid ice shell that itself could range from tens to hundreds of kilometers thick.

Beneath the probable ocean lies a rocky interior.
