Colour Striped Icebergs - Antarctica

Icebergs are formed when large blocks of ice breaks off from glaciers ice shelf and is floating in open water. Because glaciers are built up from snow falling on the Antarctic continent over millennia, this ice consists of pure fresh water. This floating chunk of freshwater ice then interacts with seawater beneath them it.

As seawater is drawn deep under the ice shelves by the oceanic currents, it becomes supercooled and freezes to the base of the ice shelf. Because this ice is formed from seawater that contains organic matter and minerals it causes variety of colour and texture to the iceberg. As the bergs become fragmented and sculpted by the wind and waves, the different coloured layers can develop striking patterns.
