The scientists used new data from NASA’s Cassini spacecraft. They were surprised to find a negative correlation between the gravity and topography signals on Titan.
“Normally, if you fly over a mountain, you expect to see an increase in gravity due to the extra mass of the mountain. On Titan, when you fly over a mountain the gravity gets lower. That’s a very odd observation,” said study co-author Prof Francis Nimmo, also from the University of California, Santa Cruz
“Because ice is lower density than water, you get less gravity when you have a big chunk of ice there than when you have water,” Prof Nimmo said.
An iceberg floating in water is in equilibrium, its buoyancy balancing out its weight. In this model of Titan, however, the roots extending below the ice sheet are so much bigger than the bumps on the surface that their buoyancy is pushing them up against the ice sheet.

Are we talking ocean like the Pacific or ocean like the Atlantic, because, the pacific has great beaches but the Atlantic is just plain dreary. I'm not booking vacation time if it's the latter...

Actually more like an Ocean of Titan and so far, no beach front property is for sale......They haven't found the beach yet??
