Elling Carlsen Carlsen made his first voyage out of Hammerfest in Finnmark, Norway. In 1859, Carlsen discovered the island group that would later be named Kong Karls Land in the Svalbard archipelago in the Arctic Ocean. Although Carlsen is credited with the finding, the islands may have been first sighted by the whaler Thomas Edge in 1617. In 1863, Carlsen completed the first circumnavigation of Spitsbergen. During a voyage to the Arctic Ocean in 1871, Carlsen discovered the lodge of Willem Barentsz on the north-eastern shore of the archipelago of Novaya Zemlya. This winter camp had been used as shelter by Barentsz
Retreat of glaciers since 1850 1977 and 1995. In the Novaya Zemlya archipelago north of Russia, research indicates that in 1952 there was of glacier ice along the coast. By 1993 this had been reduced by 8% to of glacier coastline. In Greenland, glacier retreat has been observed in outlet glaciers, resulting in an increase of the ice flow rate and destabilization of the mass balance of the ice sheet that is their source. The net loss in volume and hence sea level contribution of the Greenland Ice Sheet (GIS) has doubled in recent years from per year in 1996 to per year in 2005.
