ELEPHANT ISLAND, ANTARCTICA
Turquoise Glacial Ice
Glacial ice tends to be a blue or green turquoise color because(?): (1) The scattering of light particles as in, 'why the sky is blue'; (2) The absorption and compression of gasses trapped in the ice; or, (3) The re-freezing of melt water.   Some, all or none of the above?
