Icebergs in Antarctica 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.
.
The weather is so cold in Antartica, water freezes the instant it comes into contact with the air. The temperature of the water is already some degrees below freezing. Just look at how this wave froze in mid-air!

Isn't Mother Nature clever?
