- Blue_ice_(glacial) abstract "Blue ice occurs when snow falls on a glacier, is compressed, and becomes part of the glacier. Air bubbles are squeezed out and ice crystals enlarge, making the ice appear blue.Small amounts of regular ice appear to be white because of plenty of air bubbles inside them 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. Large quantities of water appear to be blue, as it absorbs other colours more efficiently than blue, and therefore a large piece of compressed ice, or a glacier, would appear blue.The blue color is sometimes wrongly attributed to Rayleigh scattering which is responsible for the color of sky. Rather, ice is blue for the same reason that large quantities of water are blue: it is a result of an overtone of an oxygen-hydrogen (O-H) bond stretch in water which absorbs light at the red end of the visible spectrum. In the case of oceans or lakes, some of the light, hitting the surface of water, is reflected back directly but most of it penetrates the surface interacting with its molecules. The water molecule can vibrate in different modes when light hits it. The red, orange, yellow, and green wavelengths of light are absorbed so that the remaining light we see is composed of the shorter wavelength blues and violets. This is the main reason why ocean color is blue. So, water owes its intrinsic blueness to selective absorption in the red part of its visible spectrum. The absorbed photons promote transitions to high overtone and combination states of the nuclear motions of the molecule, i.e. to highly excited vibrations. An example of blue ice was observed in Tasman Glacier, New Zealand in January 2011.".
