Аннотация: This work presents and discusses the results of ice-thickness measurements and modeling of the Greater Caucasus glaciers, using radio-echo sounding data, GlabTop model and satellite imagery. Ground and airborne radio-echo sounding measurements were conducted at selected Caucasus glaciers, including the biggest Bezengi glacier, reference glaciers Djankuat and Marukh as well as glaciers of the southern and eastern slopes of Mt. Elbrus in 2011–2013. The GlabTop model was calibrated using the measured ice-thickness data and ice-thickness and bedrock topography maps were completed for 224 glaciers (13 %) which cover 719 km2 or 64 % of the total glacier area in the Caucasus. New dataset of the Caucasus glaciers outlines was completed using available satellite imagery. There were 1713 glaciers with the surface area of 1121 ± 30 km2 in Caucasus in 2010–2013. The data obtained were used to calibrate volume-area scaling relationship and to calculate the total volume of Greater Caucasus glaciers, which is 43.5 ± 5.0 km3.
