Can you imagine how old that ice is

Blue icebergs develop from older, deep glaciers which have undergone tremendous pressure experienced for hundreds of years. The process releases and eliminates air that was originally caught in the ice by falling snow. Therefore, icebergs that have been formed from older glaciers have little internal air or reflective surfaces. When long wavelength light (i.e. red) from the sun hits the iceberg, it is absorbed, rather than reflected. The light transmitted or refracted through the ice returns as blue or blue-green.
