Not that there really is anything up there...(so far as I know) there are a number of glitches if your underwater. Mostly seaweed floating way above sea floor. Some parts are completely clear as if you were above water. (No water at all) Mostly visual glitches so far. Its like they said, hmmm no one will see this area. WRONG! One of the first places I explored. "Sea of Ghosts?" I said "Sounds awesome!" Well its not. Nothing there but water, ice and unfinished areas the developers forgot.
