eagle blue berg

Some bergs are really blue. They say that 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.
