Arctic Ice Concentration in 2006 (IMAGE) European Space Agency Caption The image on the left is an Envisat ASAR mosaic of Arctic ice acquired on Aug. 23, 2006. (Courtesy: Polar View) The right image is an EOS Aqua AMSR-E ice concentration acquired on Aug. 24, 2006. (Courtesy: Leif Toudal Pedersen). There is a significant extent of leads -- fractures and openings in the sea-ice cover -- just below the pole in both the ASAR image, seen as splashes of dark grey and black, and the AMSR-E image (with British Isles shown for scale), seen by the high concentration of yellow, orange and green colours, signifying low ice concentrations.
