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.

那深深淺淺的顏色不知道是怎麼產生的?會是因為含氣量不同而呈現的效果嗎? | |
