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 melt water 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.
- Nature is amazing!
The water froze the instant the wave broke through the
ice. That's what it is like in Antarctica where it is thecoldest 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!!!
Having the Internet means that we get to see something that we never imagined!
