Icebergs

One of them looks like a giant mint, with its clear blue, green and brown stripes.

The other looks as if it has been shot through with a streak of spearmint.



These stunning banded icebergs - formed over hundreds, if not thousands, of years - were pictured floating in the waters of the Antarctic.

Some of the stripes formed when layers of the iceberg melted and refroze.



Others were created from the dust and soil picked up when the ice sheet that gave birth to the iceberg was sliding down an Antarctic hillside.

They were photographed by Norwegian sailor Oyvind Tangen, on board a research ship around 1,700 miles south of Cape Town and 660 miles north of the Antarctic.
