  The ice shell of Enceladus exhibits strong asymmetry between its hemispheres,
with all known geysers concentrated over the south pole, even though its
orbital configuration is almost perfectly symmetric. By exploring ocean
circulation across a range of ocean salinities and core/shell heating
partitions, we study the role of ice-ocean interaction in hemispheric symmetry
breaking. We find that: (i) asymmetry is enhanced by cross-equatorial ocean
heat transport when the ice shell is the major heat source and vice versa, (ii)
the magnitude of ocean heat transport is comparable to the global heat
production, significantly affecting the ice shell evolution and equilibrium
state and (iii) more than one equilibrium state can exist due to a positive
feedback between melting and ocean circulation.
