FRANZ JOSEF LAND, RUSSIA - 16-19 Aug 2011 - Located just 600 miles (970 kilometers) from the North Pole, Franz Josef Land in the Arctic Sea of Russia is perpetually coated with ice. Glaciers cover roughly 85 percent of the archipelago’s land masses, and sea ice floats in the channels between islands even in the summertime. Most of the ice in this scene is anchored to land, as large glaciers blanket the islands. Yet today’s glaciers are tiny compared to the ice sheet that dominated the region about 20, 000 years ago. Studies of Franz Josef Land have actually contributed to a larger understanding of when that massive ice sheet began its slow retreat. Raised beaches, which preserve evidence of land rising as the crushing weight of overlying glaciers eases (known as isostatic rebound), were first recognized on the islands in the late nineteenth century. Researchers estimate that the giant ice sheet had retreated by about 10, 000 years ago - Photo: Geopix/NASA/GSFC/METI/ERSDAC/JAROS/ASTER
