Icebergs may also appear blue due to light refraction and age. Older icebergs reveal vivid hues of green and blue, resulting from a high concentration of color, microorganisms, and compacted ice. [5] An iceberg of “electric blue” colour in the waters off Sermilik fjord near Greenland in 2009 was named by locals the "blue diamond". [6]
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. Such blue-ice areas typically form when the movement of both air and ice are obstructed ...
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.

This is a list of icebergs by total area. In 1956, an iceberg in the Antarctic was reported to be an estimated 333 kilometres (207 mi) long and 100 kilometres (62 mi) wide. Recorded before the era of satellite photography, the 1956 iceberg's estimated dimensions are less reliable.
An iceberg larger than Rhode Island broke off from the Ronne ice shelf in Antarctica's Weddell Sea mid-May, and a satellite operated by European scientists captured the moment the massive piece of ...

On the expedition in the Gerlache Strait, biologist Emil Racoviță made several discoveries, including a flightless midge fly that was later formally named Belgica antarctica by the Belgian entomologist Jean-Charles Jacobs. [1] The Gerlache Strait has spiky blue icebergs, and is widely considered a great spot for whale-watching.
One of the world’s largest icebergs is drifting beyond Antarctic waters, after being grounded for more than three decades, according to the British Antarctic Survey. The iceberg is about three ...
