What Causes Antarctica’s Stunning Striped Icebergs?

Antarctica is home to some incredible vistas and unusual wildlife but one of the strangest sights to be found in this winter wonderland comes in the form of striped icebergs. It would be easy to assume the stripes are man-made but the different layers actually form due to a number of natural reasons: the melting and refreezing of the ice can create blue stripes in the icebergs, the rich algae in the water can often create green stripes, while sediment picked up from the ground before the bergs slide into the sea can often cause black, brown and even yellow stripes. Whatever the reasons for the stripes, there is no doubting the stunning results.
