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.
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]
The surprisingly blue cast to this ice is caused by a lack of air trapped inside the glacier, which causes blue light to be trapped inside.
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.

A large piece of compressed ice, or a glacier, appears blue, as large quantities of water appear blue, because water molecules absorb other colors more efficiently than blue. The other reason for the blue color of glaciers is the lack of air bubbles.
Climate change is accelerating the melting of the world's mountain glaciers, according to a massive new study that found them shrinking more than twice as fast as in the early 2000s. The world's ...
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]
Internal deformation occurs when the weight of the ice causes the deformation of ice crystals. This takes place most readily near the glacier bed, where pressures are highest. There are glaciers that primarily move via sliding, glacial quakes, and others that move almost entirely through deformation.
