Axel Hieberg Island, Canada
Axel Heilberg Island in Canada's arctic. Note the blocks of ice that have calved off the foot of the glacier (middle-bottom), as well as the melt feature and stream (bottom-right). This photograph was taken from on-board NASA's Lockheed Martin P-3B aircraft during ARCTAS, a NASA-funded contribution to POLARCAT, a core activity of the 2007/2008 International Polar Year.
