Striped Icebergs

Icebergs in the Antarctic area sometimes have stripes,
formed by layers of snow that react to different

conditions.



















Brown, black and yellow lines are caused by sediment,

picked up when the ice sheet grinds downhill towards

the sea.


















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.

































Antarctica Frozen Wave Pixs - 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 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. And Just look at how the wave

froze in mid-air!!!
