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.
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
[25] [26] [27] 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.
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 ...
Light scattering by suspended matter is required in order that the blue light produced by water's absorption can return to the surface and be observed. Such scattering can also shift the spectrum of the emerging photons toward the green, a color often seen when water laden with suspended particles is observed. [citation needed]
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 ...
However, the 1980 eruption of Mount St. Helens eliminated nine of its eleven named glaciers and only the new glacier known as Crater Glacier has been reestablished since. Olympic Mountains Mount Olympus. Blue Glacier; Hoh Glacier; Hubert Glacier; Humes Glacier; Ice River Glacier; Jeffers Glacier; White Glacier; Other peaks in the Olympic ...
Here's a breakdown of how and why it all happens. But the science behind a blue sky isn't that easy. For starters, it involves something called the Rayleigh effect, or Rayleigh scattering.
