Ice refracts (bends) light as it
passes through it, by some special magic physics stuff, this is
why it looks blue if it doesn't look white, the other colours
are hidden by the ice pixies. This particular bit of ice had the
deep blue colours keep popping out from where the ice pixies hid
them and so they moved around as I moved my eyes and camera
around which I took great delight in doing.
These are pictures
from a cruise to the High Arctic in August 2010, from Resolute
Bay Canada to Kangerlussuaq in Greenland.
