Watershed between the Black and Caspian seas. The Greater and Lesser Caucasus are connected by the Likhi Range, which represents the Systems: the Greater Caucasus (the higher and more extensive part) extends for ∼ 1300 km from northwest to southeastīetween the Black and Caspian seas, while the Lesser Caucasus, approximately 100 km to the south, is characterized by The Caucasus mountains consist of two separate mountain On manual delineation of glaciers from multi-temporal satellite images and especially to fill the gap in the eastern Greater Thus, the objectives of this paper are to construct an updated glacier inventory for the Greater Caucasus region based The Caucasus for the GLIMS book (Kargel et al., 2014), the Nobody volunteered to write a section about the glaciers in World Glacier Inventory – Extended Format (WGI-XF Cogley, 2009) these are omitted from the GLIMS database. Incorporates nominal glaciers as circles in the eastern and Of 1638 glaciers with a combined area of 1276.9 km2 and The Randolph Glacier Inventory (RGI5) database identifies in excess The Global Land Ice Measurements from Space (GLIMS)ĭatabase (9 February 2017) for the Greater Caucasus identified in excess of 1295 glaciers with a combined area ofġ111.8 km2 but with some inconsistent registration. Wheate: The Greater Caucasus Glacier Inventory Published by Copernicus Publications on behalf of the European Geosciences Union. Georgia, with thousands of visitors each year (Georgian National Tourism Administration, 2017). The GreaterĬaucasus glaciers also have economic importance as a major Mudflow killing nine people (Tielidze, 2017). Glacier (Georgia) caused a rock–ice avalanche and glacial People (Evans et al., 2009), and on Devdoraki OnĢ0 September 2002, for example, Kolka Glacier (North Ossetia) initiated a catastrophic ice-debris flow killing over 100 However, glacier hazards are relatively common in this region, leading to major loss of life. Most rivers originate in the mountains, and the melting of glaciers/snow is an important component of the inputs in terms of water supply and for recreational opportunities (Tielidze, 2017). Glaciers are an important source of water for agricultural production, and runoff supplies several hydroelectric power stations. In a high mountain system such as the Greater Caucasus, Glacier inventories are invaluable data sets for revealing theĬharacteristics of glacier distribution and for upscaling measurements from selected locations to entire mountain ranges (Gardner et al., 2013 Radic and Hock, 2014). Mass balance and volume change, which are relevant to localto regional-scale hydrological studies (Huss, 2012 FischerĮt al., 2015) and to global calculation of sea level change Glacier inventories provide the basis for further studies on (GLIMS) database and can be used as a basis data set for This new glacier inventory has been submitted to the Global Land Ice Measurements from Space Glacier mean size decreased from 0.70 km2 in 1960 to 0.66 km2 in 1986 and toĠ.57 km2 in 2014. Total glacier surface area between 19 and an increase in the rate of area loss since 1986 (0.69 % yr−1 ) compared to 1960–1986 (0.44 % yr−1 ). Mountains contained 2349 glaciers with a total glacier surface area of 1674.9 ± 70.4 km2.
