Actually, Svartisen means black ice. However, the ice of the glacier tongue of Engabreen, an outlet glacier of Svartisen ice cap, looks pretty blue in the lights of late afternoon. If the ice is mostly free of air bubbles, the ice transmits the blue color more than the rest oft the visible spectrum of light. Thus, by having a path of approx. 3 m through the ice bodie, particularely the blue light is visible.
