Icebergs Comes In Stripes.

The Norwegian sailor Oyvind Tangen when on a research in the Antartic, came across unusual black lines striped through an iceberg.

Most of them appear white due to the tiny bubbles within them that scatter light in all directions. When a crevice in the ice sheet or a part of an iceberg melts and quickly refreezes, then bubbles are not formed and it can appear blue.

When an iceberg falls into the sea, a layer of salty seawater can form ice on its underside. If that is rich in algae, it can form a green stripes. Brown, black and yellow lines are formed by sediments, that might be picked up when the ice sheet is on its way downhill towards the sea.
