Blue ice (glacial) - Wikipedia
Blue ice occurs when snow falls on a glacier, is compressed, and becomes part of the glacier. During compression, air bubbles are squeezed out, so ice crystals enlarge. This enlargement is responsible for the ice's blue colour.
Why is glacier ice blue? - Woods Hole Oceanographic Institution
When sunlight shines on a field of snow, it reflects a bright—even blinding—white. But if you get a good look at the leading edge of a glacier, you’ll find that the ice inside is a brilliant blue. The surface may look white, but places where the ice has cracked open look almost turquoise.
Why is glacier ice blue? | U.S. Geological Survey - USGS.gov
Glacier ice is blue because the red (long wavelengths) part of white light is absorbed by ice and the blue (short wavelengths) light is transmitted and scattered. The longer the path light travels in ice, the more blue it appears.
Why is the Ice Blue? In Glacier Bay - U.S. National Park Service
2021年4月8日 · Like sapphires, glacial ice reflects the blue colors of the light spectrum, so beautiful blue color reaches our eyes. Glacial ice mostly looks white, since it is typically jagged and worn from exposure. Glacial ice can also look black and brown from the rock and debris plucked up by the ice in its journey down the mountainside and incorporated ...

蓝冰的蓝色和和大量液态水呈现蓝色的原因相同，是 水分子 中氢氧键 伸缩振动 （英语：Rotational-vibrational spectroscopy） 的 泛频带 （英语：Overtone band） 会吸收 可见光 谱中红色端的部分所致 [1]。 在 湖泊 和 海洋 中，光线入射到水面上时，少量的光反射回空气，大部分光进入水中，与水分子发生作用。 此时，水分子会吸收入射光中的红、橙、黄等颜色的光，跃迁至较高的 振动能级，而未被吸收的光主要是蓝、紫色波长的光。 这是大面积水域呈现蓝色的主 …
Blue-ice area - Wikipedia
A blue-ice area is an ice-covered area of Antarctica where wind-driven snow transport and sublimation result in net mass loss from the ice surface in the absence of melting, forming a blue surface that contrasts with the more common white Antarctic surface.
Why Are Some Glaciers Blue? - Live Science
2015年5月30日 · Patches of blue-hued ice emerge where wind and evaporation have scoured glaciers clean of snow. The translucent, wind-polished surface reflects a stunning turquoise color when the polar sun...
Blue iceberg - Wikipedia
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] …
What causes the blue color in glaciers? - Geographic Pedia - NCESC
2024年6月27日 · Blue ice is the color of pure glacier ice that is compact and contains few air bubbles. The weight of the ice squeezes out the air, resulting in a dense ice formation. Similar to sapphires, glacial ice reflects the blue colors of the light spectrum, creating its beautiful blue hue.
The Rare Phenomenon Of Blue Ice - Indiana Public Media
Red and yellow bands of the light spectrum are absorbed, while blue light is reflected, resulting in the glacier's blue, almost turquoise hue. The phenomenon is similar to that which makes...
