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 meltwater 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.
