In glaciers, the pressure causes the air bubbles to be squeezed out, increasing the density of the created ice. Water is blue in large quantities, as it absorbs other colours more efficiently than blue. A large piece of compressed ice, or a glacier, similarly appears blue.
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] Icebergs may also appear blue due to light refraction
Glaciers are large bodies of ice and snow formed in cold climates by processes involving the compaction of fallen snow. While snowy glaciers appear white from a distance, the long path lengths of internal reflected light causes glaciers to appear a deep blue when viewed up close and when shielded from direct ambient light.

Glacier ice is slightly more dense than ice formed from frozen water because glacier ice contains fewer trapped air bubbles. Glacial ice has a distinctive blue tint because it absorbs some red light due to an overtone of the infrared OH stretching mode of the water molecule. (Liquid water appears blue for the same reason.
A glacier in the Transantarctic Mountains.Blue ice is seen as a lighter blue in the photograph, while the darker blue is formed by re-frozen melt ponds. Blue-ice areas have a generally smooth and often [1] rippled appearance, a blue colour [2] and a sparseness of bubbles in the ice. [3]
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".
Water flowing out from underneath Antarctic glaciers could be causing them to lose ice at a faster rate ... named Denman and Scott. Together, these glaciers hold enough ice to cause nearly five ...
A glacier stream is a channelized area that is formed by a glacier in which liquid water accumulates and flows. [1] Glacial streams are also commonly referred to as "glacier stream" or/and "glacial meltwater stream". The movement of the water is influenced and directed by gravity and the melting of ice. [1]
