An iceberg in the Arctic Ocean. An iceberg is a piece of fresh water ice more than 15 meters (16 yards) long [1] that has broken off a glacier or an ice shelf and is floating freely in open water. [2] [3] Smaller chunks of floating glacially derived ice are called "growlers" or "bergy bits".
Blue iceberg observed by tourists along the coast of Alaska, 2010. A blue iceberg is visible after the ice from above the water melts, causing the smooth portion of ice from below the water to overturn. [1] [2] The rare blue ice is formed from the compression of pure snow, which then develops into glacial ice. [3] [4]
However, they start floating as icebergs when their size is small enough to drift to the sea. These icebergs are seen in two shades: milky white and bright blue, which depends on the air trapped within the ice and is an interplay of light and ice crystals.
The blue colour will not be seen again until the ice breaks or turns over to expose ice which air could not reach. For example, lucky tourists at Tasman Glacier, New Zealand in January 2011 saw an iceberg roll over to reveal startling blue ice, kept from air by staying underwater for months since the iceberg calved.

The Sea of Ice represents what Friedrich believes the Arctic looks like. [6] In the foreground of the painting there are small icebergs layered on top of each other, which makes them almost look like steps. In the background, however, the icebergs are crushed together to form a tower of ice. [7]
Take a look at what lies beneath the water in images of a flipped iceberg. Filmmaker Alex Cornell went to Antarctica to photograph the landscape, Rare look at what lies beneath icebergs
A blue-ice area in the Miller Range with a meteorite. A blue-ice area is an ice-covered area of Antarctica where wind-driven snow transport and sublimation result in net mass loss from the ice surface in the absence of melting, forming a blue surface that contrasts with the more common white Antarctic surface.
