Try solid ice-foam. Closed cell ice foam on the lake bed would be buoyant in methane. Either it could be formed currently by being erupted from the seabed in some cryovolcanic process or it could be there already just waiting for some disturbance to dislodge it so it can float up.

Either it could be formed currently by being erupted from the seabed in some cryovolcanic process or it could be there already just waiting for some disturbance to dislodge it so it can float up. Solid ice-foam is a good suggestion, and I'd really like to get the idea to float. But the process would need to be just right to create foam bubbles of the right size and thickness to make all parts of this island buoyant. Now that the total size is rather large, this mechanism creating the bubbles would also have to work evenly over a sizeable part of this feature. So I am stuck in the icy reef, and the ice hypothesis here. =) |
