Stripped Icebergs.

Hi all,
As the cold weather seems to be very topical, at least in this country for now, thought i would share these pictures with you all, nothing to do with the shop or website but great pictures all the same, they were sent to me a few months ago.

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.
These pictures are available because 2008 was the coldest winter.



The awesome power of Nature.
