Some people claim that these are pictures of water that instantly froze when it came in contact with the air. Well, I know it's cold in Antartica but the day a tidal wave or a tsunami wave will instantly freeze while breaking has not come yet. You can rest assured Armageddon is not for tomorrow.
These photos are nonetheless fantastic. You'll notice that there is blue ice, which is created as the ice is compressed and trapped air bubbles are squeezed out. The ice looks blue because, when light passes through thick ice, blue light is transmitted back out but red light is absorbed. I didn't figure that out by myself of course, but I did some research. Now enjoy the pictures and thank the mighty internet for providing more info about those so-called "frozen waves"!
