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 an d 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. To see more photos please visit Watery Wednesday and join us.
