A diver swimming beneath thick ice is silhouetted against the green glow of the Northern Lights. Irish photographer George Karbus went to extraordinary lengths to capture this image in bitterly cold waters of Russia's White Sea in the Arctic Circle. George, 33, his girlfriend and a friend ventured out from the shore, cut a hole in the foot-thick ice and took the plunge. He dipped below his girlfriend Kate Hamsiaora - who was swimming some six metres under the ice - to get this beautiful shot while the the aurora borealis illuminated the night sky.
