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.
The water froze the instant the wave broke through the
ice. That's what it's like in Antarctica where it is the
coldest weather in decades. Water freezes the instant
it comes in contact with the air. The temperature of the
water is already some degrees below freezing.
Just look at how the wave froze in mid-air!!!
