Striped Icebergs

Post by 2nd Reef » Wed Jun 18, 2008 8:50 pm

Got these shots sent to me today. Some of you may be interested....

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.

Yep, very nice. I received those last two through the email, with, as Ben points out, the caption that it was a frozen wave. Not bloody likely.

And Ben, your site says that you can't even track down whether it was in Antarctic or the Arctic. I'm betting it ain't the arctic, even though it came with a batch of other pictures of the northern lights.
