Icebergs can appear white blue green brown or black. The colourations are caused by impurities or difference in density. The dark layers seen here indicate the presence of rock materials from the base of the glacier. The famous blue colour is a result of extremely compact ice that is also likely to be extremely old.

Why is glacial ice so blue?
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.

Scientists believe that iceworms feed on snow algae pollen grains ice and snow. In turn iceworms are preyed upon by snow buntings and other birds.
Why is glacier water so blue?
A large piece of compressed ice or a glacier similarly appears blue. … Rather water ice is blue for the same reason that large quantities of liquid 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.

Would Titanic have sunk today?
Answer: There is no definitive answer but it would probably have sunk anyway. When you hit an iceberg the ship below the water will hit the iceberg before the ship above the water line so it would divert it off its course – it’s not like hitting a brick wall head-on.
