Adventure Lifers tackle the national park (Beth Conway)
The short answer is it has to do with the the light spectrum, and the way light is filtered through the ice. The thicker the ice, the more blue-green color it displays. Regardless of what our on board geologist, Wolfgang, might suggest, the blue color IS NOT a result of reflecting light off the blue eyes of the rare Antarctic ice worms... Oh, geologist-humor!
