Amazing striped icebergs
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.
