Glacier in Iceland

According to NASA glaciologist Dorothy Hall, Landsat data show that
Iceland's Breidamerkurj¦kull has receded by as much as 2 km since 1973.
The Breidamerkurj¦kull is an outlet glacier, which is part of Vatnaj¦kull--
the largest ice cap in Europe. Hall notes that all but one of the Vatnaj¦kull's outlet
glaciers, roughly 40 named glaciers in all, are currently receding. Although all of
Iceland's outlet glaciers are currently retreating, some glaciers
like the Breidamerkurj¦kull expand and retreat independent of short-term climate.
Therefore, glaciologists must exercise caution when attributing glacier movements
in the lake to climate change. As the glacier retreats, you can see the creation of
smaller icebergs formed by the glacier. In this scene, bare glacier ice surfaces appear
bluish-white, while those covered by snow are bright white. Water surfaces are dark blue
and land surfaces appear reddish.
