Striped Icebergs

Posted by Miss Cellania in Pictures on March 18, 2008 at 9:55 am


150_BergIcebergs 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.

    I think you only find Yeti tinkle in Artic icebergs.

    Yeti tinkle would be in Himalayan icebergs. There aren't too many of those.

    Penguin tinkle, maybe.

    I first read this as "Stupid Icebergs."

    The Yeti has a mighty stream and extraordinary aim. Unfortunately their tinkle is warm and is a major contributing factor, along with global warming, to artic ice loss.
