Amazing ! Why Are Icebergs Blue
An icebergs color is determined by how it interacts with light. Some glaciers and icebergs are blue for the same reason water is blue.

The fewer bubbles there are the less chance there is of light being scattered.
Why are icebergs blue. Most of us think of icebergs as white but they actually come in a range of shades between bright blue and dark green. A thin sheet of glass looks clear but if you loo. Icebergs form when chunks of freshwater ice calveor break offfrom glaciers and ice shelves as well as other icebergs.
Why is Blue Ice Blue. Why are icebergs different colours. All were brilliant blue at their core.
This is known as colour addition. These variations in color can be impacted by factors such as the presence of algae absence of air bubbles and the seawater composition. They put the Koh-i-Noor to shame.
How does gravity make an iceberg flip. However lets think about it. The bottom of icebergs are blue because ice is faintly blue as is water.
Icebergs can be green blue yellow or black. We never expected to see green icebergs The answer is simple. Back-lit clouds are gray or dark gray.
Icebergs are also grouped according to their shape. The icebergs are scattered over the beach and float in the ocean coming in many shapes and sizes. While this makes them far more dangerous to shipping than they appear it does mean.
Blue icebergs are relatively rare in the waters surrounding Antarctica. Pure icebergs naturally reflect a blue color as ice crystals reflect short blue wavelengths. 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.
Blue-ice areas are also used as runways for landing aircraft with wheels instead of skis. Blue glaciers and icebergs are not blue for the same reason the sky is blue. The force of gravity makes an iceberg flip.
Passing light through such an iceberg will have the weaker red wavelength of light be absorbed by the ice leaving the more high energy blue light to pass through the iceberg and into your eye and so you see it as being blue. If the ice is compressed the bubbles are squeezed out and the blue light is scattered much more than other colors making the ice appear blue. Governments including Italy Australia Norway Russia and the United States all operate blue-ice runways.
The coolest ones had striations all along their sides like they were cross-sectioned so we could see the story of their formation laid bare. Researchers have proposed a new idea that may explain why some Antarctic icebergs are tinged emerald green rather than the normal blue potentially solving a decades-long scientific mystery.

The longer the path light travels in ice the more blue it appearsLearn more. Ice and water absorb less blue light than other frequencies so when there is enough ice it. This is down to how much oxygen is in the ice more oxygen gives a white colour a little oxygen gives an ice blue colour and then theres the rare no-oxygen icebergs these are completely colourless like huge floating diamonds.
So why are the icebergs green. Why do icebergs look blue. USGS Water Science School - Glaciers.
They are far older than white tabular icebergs originating from portions of a glacier that are very compressed. Then theres the size of them. Most icebergs are white in color but some may appear blue or even green.
These icebergs are bigger than toppled skyscrapers. Many were huge and had exciting colouring. The chemical bond between oxygen and hydrogen in water absorbs light in the red end of the visible light spectrum.
See this image for example. The ice can shine like a sapphire or be as murky as a frozen mud puddle. In ice this results in red wavelengths being absorbed with only blue light being scattered and escaping the iceberg.
Icebergs are notorious for keeping around 90 per cent of their bulk hidden beneath the surface of the sea. There are smaller ice sculptures too in every imaginable shape and limitless blue hues. Why Icebergs are Blue.
Glaciologists have proposed a new theory to explain why some Antarctic icebergs are tinged emerald green rather than the normal blue. Chinstrap penguins gather on a blue iceberg near Candlemas Island. I am not sure I have the complete story on this.
This means we see a blue colour. Ice is full of tiny air bubbles that scatter all color wavelengths the same amount giving the ice a white appearance. The big drop in the absorption coefficient is slightly below 500 nm blue is around 450.
Front-lit clouds are white as long at the Sun is above 20 degrees in elevation. Most icebergs are white. Just one of the ginormous icebergs in Iceberg Alley.
In Iceberg Alley in the Weddell Sea colossal tabular icebergs bigger than downtown buildings are luminescent in their blueness. Even mountain-sized icebergs weighing hundreds of millions of tonnes have been known to flip over creating tsunamis capable of swamping nearby vessels. The sky is blue due to atmospheric scattering of light Raleigh.
Mixing coloured light together always makes white. Some are even striped. An iceberg is usually white in color since it is covered by snow but it can also be black yellow blue or green.
