Assessment of area, volume and ELA of glacial systems in Northeast Russia from satellite images in the beginning of XXI century
The paper compares remotely sensed glacier inventories of the Byrranga, Suntar-Khayata, and Chersky ranges (2003), Koryak Highland and Chukotka mountains (2008) with data from the Inventory of Glaciers of the USSR (1945–1985). We studied changes in glacier area since the Inventory, which was primari...

The paper compares remotely sensed glacier inventories of the Byrranga, Suntar-Khayata, and Chersky ranges (2003), Koryak Highland and Chukotka mountains (2008) with data from the Inventory of Glaciers of the USSR (1945–1985). We studied changes in glacier area since the Inventory, which was primarily based on aerial photos and field research. The glaciers have been classified by orientation (aspect) and morphological type. Overall the glacierization of the Chersky Range (1970–2003), Suntar-Khayata (1945–2003), Byrranga (1967–2003), Koryak Highland (1950–2003) and Meynypilginsky Range (1984–2008) reduced by about 30, 20, 15, 60 (debatable value) and 25% respectively due to summer temperature rise.
