Icebergs in the Antarctic area sometimes have stripes, formed by
layers of snow that react to different conditions.
Blue stripes are often created when a crevice in the ice sheet fills
up with meltwater and freezes so quickly that no bubbles form.
When an iceberg falls into the sea, a layer of salty seawater can
freeze to the underside. If this is rich in algae, it can form a
green
stripe.
Brown, black and yellow lines are caused by sediment, picked up when
the ice sheet grinds downhill towards the sea.
