    (Yet another e-mail, but I thought these were really neat!!

    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.
