A Yacht floating under the water

Nature is quite amazing and it has some amazing phenomenon. Some things happen to us which makes us feel amazed. A thing like this happened in Antarctica, a yacht sunk in the water and the surface of water got frozen.

The sunk yacht can be seen in the picture which is floating under the water. Water has a unique trait as it does not freeze completely and only the surface of water freezes. Is not it an interesting and amazing photo? I have never seen such a thing before!
