Blue-Green Antarctic Glacier

Looking through this iceberg's reflection in the Antarctic water, you can see the iceberg below the surface—some 90% of its total volume. Icebergs are pieces of freshwater ice broken off of glaciers or ice shelves, left to float across the sea. Many icebergs and other pieces of floating ice cram together, freezing into pack ice, which is a form of sea ice.
