It's turning back into the liquid form. When it melts, it will put back the volume of water that was displaced for lifting the solid.
The ice cube's submerged portion occupies the volume of water that is equal to the weight of the ice. Density is irrelevant. If the ice displaces 2 pounds of water, then the ice weighs 2 pounds, and therefore will not displace less or more than that when it melts. Try this: add some ice to a glass of water and mark the meniscus. Check it after the ice melts and if it's any different, let physicists know because you've just done some incredible voodoo witchcraft.
