Formation of new periglacial lakes in the Grønfjord basin (Svalbard) in 1938–2010
Based on remote sensing and field methods, the state of the glacial lakes located in the Grønfjord Bay basin, Svalbard, was assessed for 2008–2010. New lakes were formed due to the retreat of the mountain-valley glaciers of the Nordenskiöld Land and the formation of moraine-ridge topography. Accordi...
