Striped Icebergs

Icebergs sometimes have stripes, formed by layers of ice deposited on different conditions. Blue stripes are created when a crevice in the ice sheet fills up with melted water and freezes so quickly that no bubbles form. Green stripes form when an iceberg falls into the sea and a layer of water rich in algae freezes onto the bottom.  Brown, black and yellow lines are caused by sediment, picked up when the ice sheet grinds downhill towards the sea.
