There have been numerous studies of glaciers in 1 Introduction the Greater Caucasus, but none that have generated a modern glacier database across the whole mountain range. Here, we Glacier inventories provide the basis for further studies on present an updated and expanded glacier inventory at three mass balance and volume change, which are relevant to local- time periods (1960, 1986, 2014) covering the entire Greater to regional-scale hydrological studies (Huss, 2012; Fischer Caucasus. Large-scale topographic maps and satellite im- et al., 2015) and to global calculation of sea level change agery (Corona, Landsat 5, Landsat 8 and ASTER) were used (Gardner et al., 2013; Radic and Hock, 2014). In addition, to conduct a remote-sensing survey of glacier change, and glacier inventories are invaluable data sets for revealing the the 30 m resolution Advanced Spaceborne Thermal Emission characteristics of glacier distribution and for upscaling mea- and Reflection Radiometer Global Digital Elevation Model surements from selected locations to entire mountain ranges (ASTER GDEM; 17 November 2011) was used to determine (Nagai et al., 2016).
