Axel Heilberg Island in Canada's Arctic, is shown in an April 8, 2008 image. 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 obtained from on board the NASA P-3B aircraft during ARCTAS, a NASA-funded contribution to POLARCAT, a core activity of the 2007/2008 International Polar Year.
