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. The blue color is sometimes wrongly attributed to Rayleigh scattering, which is responsible for the color of the sky.
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 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
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 ...
Water color can reveal physical, chemical and bacteriological conditions. In drinking water, green can indicate copper leaching from copper plumbing and can also represent algae growth. Blue can also indicate copper, or might be caused by syphoning of industrial cleaners in the tank of commodes, commonly known as backflowing.
Rapper-turned-actor Chris “Ludacris” Bridges sparked concern from some social media followers when he knelt on an Alaska glacier, dipped an empty water bottle into a blue, pristine pool of ...

Ice streams are a type of glacier [5] and many of them have "glacier" in their name, e.g. Pine Island Glacier. Ice shelves are listed separately in the List of Antarctic ice shelves. For the purposes of these lists, the Antarctic is defined as any latitude further south than 60° (the continental limit according to the Antarctic Treaty System). [6]
