“…Only Malyi Azau Glacier had a relative loss in the expected range (1.8%). The important relative losses for the Dzhikiugankez Glacier can be explained by the role of the intense post-volcanic activity, especially the influence of thermal and fluid flows in the north-eastern part of the Elbrus volcano (Masurenkov and Sobisevich, 2012).…”

ABSTRACT. The glacier system covering Europe's highest mountain, Elbrus, has exhibited an accelerated retreat since 1980. Some studies have related this retreat to a significant summer temperature increasing trend. Relief-and aspect-related parameters for the glacierized area have an important impact on glacier changes. In this paper, the changes in glacier area are identified, quantified and correlated with relief parameters for the period 1985-2007. Spatial analysis was performed using the GLAM-CD (Glacier Mapper -Change Detector) algorithm. The input data for this algorithm were Landsat 5 images, the Aster Global Digital Elevation and the glacier outlines from the GLIMS project (Global Land Ice Measurements from Space). Regression analyses between glacier area losses and relief-related parameters indicate a significant positive relation with the altitude and a significant negative relation with the glacier surface area. In this context, we used a correlated component regression to model these relations. The model explains >50% of the total variation.

“…Among the large glaciers (> 10 km 2 ), Dzhikiugankez Glacier experienced a high rate of reduction, as the most extensive glacier on the Elbrus massif; the relative loss was 27.2 ± 1.2 % (0.50 % yr −1 ) between 1960 and 2014. The important relative losses for Dzhikiugankez Glacier can be explained by the role of post-volcanic activity, especially the influence of thermal and fluid flows in the northeastern part 1960-1986, 1986-2014 and 1960-2014. of the Elbrus volcano (Masurenkov and Sobisevich, 2012;Holobâcȃ, 2016).…”
