Fabulous Rainbow Iceberg
clipped from www.telegraph.co.uk Resembling a strange creature from the deep, this rare marbled iceberg was spotted in the waters of the Antarctic by a Norwegian sailor Oyvind Tangen, 62, was on board the research ship G O Sars when he photographed the unusual ice formation, floating a few miles off the coast of the frozen continent While most icebergs are white due to tiny bubbles trapped inside, which scatter the light in every direction, some pick up a multitude of colours due to various natural phenomena
Deep blue lines can also appear when the air bubbles are squeezed out due to rapid melting and re-freezing of the ice. |
