It's not everyday that you get to see an iceberg and it's even rarer that you get to see one flip over, but thats exactly what happened right in front of photographer Alex Cornell whilst he was on an expedition in Antarctica last month. Apparently what you see on the surface of the water is only one tenth of the icebergs actual size making the whole event of one flipping over incredibly rare.
Icebergs are snowy on top however these photographs show the underside of one is the polar opposite. It looks like a crystal clear fragment of glass being filled from a deep blue glow given off from the ocean below.
