Small amounts of regular ice appear to be white because of air bubbles inside and also because small quantities of water appear to be colourless. 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 ...
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.

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.
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]
Alaska's mighty Muldrow Glacier is moving 50 to 100 times faster than normal. It's a major surge. Large parts of the 39-mile-long "river of ice" are progressing some 30 to 60 feet per day, as ...
The glacial ice appears blue as a result of the absorption of red, orange, yellow and green wavelengths of light and, consequently, pools of meltwater on top of the glacier will appear bright blue. Margerie Glacier is a much cleaner glacier with less debris compared to the Grand Pacific Glacier located adjacent to Margerie's northeastern flank.
