That picture IS fake there's no way that light can penetrate that far down in the ocean to generate that kind of glimmer off that ice, especially if the sun was supposedly directly overhead..if it's directly overhead, how would it be able to even reflect off of the part directly underneath the tip, and all the way at the bottom? i understand Water sends light flying in all directions, but not concentrated enough to get that sort of reflection even IF light could penetrate that deep..
Still a neat pic though, but not real.
