An iceberg in the Arctic Ocean Icebergs in Greenland as filmed by NASA in 2015. An iceberg is a piece of freshwater 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]
Though the size of the ice floes is affected by the seasons, even a small change in global temperature can greatly affect the amount of sea ice and due to the shrinking reflective surface that keeps the ocean cool, this sparks a cycle of ice shrinking and temperatures warming. As a result, the polar regions are the most susceptible places to ...
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
The split of the A38-B iceberg is recorded in this series of images. The iceberg was originally part of the massive A-38 iceberg, which broke from the Ronne Ice Shelf in Antarctica [3] B-15A: 6,400 2002 Northern edge of Iceberg B-15A in the Ross Sea, Antarctica, 29 January 2002: A-68: 5,800 175 50 2017 Calving crack in the Larsen C ice shelf [2 ...
The colossal iceberg known as A23a has been slowly spinning in one spot of the Southern Ocean since April. Here’s what experts have to say on the phenomenon. The world’s largest iceberg is ...
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 world's largest iceberg is on the move for the first time in more than three decades, scientists said on Friday. At almost 4,000 square km (1,500 square miles), the Antarctic iceberg called ...
