每日邮报的冰冻“海浪”欣赏
本帖最后由 人与自然 于 2012-11-27 01:11 编辑来源：http://www.dailymail.co.uk/news/article-2238603/Frozen-waves-blue-ice-photographed-Tony-Travouillon.html
At first glance these beautiful images from the Antarctic appear to show 50-ft tall waves that have been instantly frozen as they break.
Some people have posted the pictures online, taken by scientist Tony Travouillon at Dumont D'Urville, with a description claiming they are a tsunami wave which was frozen.
But although email chains and internet forums back this claim up, what is really pictured is the natural phenomenon of blue ice.
简单翻译一下，这些看起来很像波浪的冰，其实并非波浪瞬间冷冻形成，而是冰层的压力所致，导致冰层中间的气泡被挤压出去。
夏天冰层表明融化，但是新雪有降落下来压在上面，长期积压于是形成这种奇观。
至于为何呈现蓝色，是因为当阳光照射时候，红色光被冰层吸收，而蓝色光被反射出来所致。

Frozen towers: This blue ice is created because ice bubbles are compressed and light at the red end of the spectrum is absorbed

Stunning: It's easy to see why people might believe this is just part of a frozen ocean, but the truth is still interesting, if a little more complex
'You can even see a gradation of colour within a hole poked in clean, deep snow. Near the opening, the transmitted light will be yellowish.
'As the depth increases, the corer will pass through yellowish-green, greenish-blue and finally vivid blue. If the hole is deep enough, the colour and light disappear completely when all the light is absorbed.'
Mr Travouillon, employed by Caltech in California, travelled to Antarctica while working towards his PhD from the University of New South Wales, Sydney Australia.
The 35-year-old lists his nationalities as Australian and French and can speak both Spanish and French, as well as English.
On his resume he writes: 'My research is mainly experimental covering a broad knowledge of site testing, remote sensing and automatization for telescopes of all wavelengths.
'I am also particularly interested in the development and management of very large astronomical projects.
'My career goal is to work in a hybrid environment of academia and project research, involving myself in teaching and project development.'

想起了主席老人家的“沁园春雪" 外面看像一块蓝色的三文鱼肉:lol 祖国江山一片白。。
这个怎么形成的，一瞬间冻住的吗
