Glacier classification from Sentinel-2 imagery using spatial-spectral attention convolutional model
International Journal of Applied Earth Observations and Geoinformation, 2021 Glaciers are critical components of the cryosphere and most sources of water. The Sentinel-2 imagery provides an efficient and cost-effective way for the production of inventories of glaciers.

A comparison of glacier melt on debris-covered glaciers in the northern and southern Caucasus [PDF]
, 2011 The glacier coverage in the Caucasus Mountains underwent considerable changes during the last decades. In some regions, the observed reduction in glacier area is comparable to those in the European Alps and the extent of supra-glacial debris increased on

Multi-sensor remote sensing to map glacier debris cover in the Greater Caucasus, Georgia
Journal of Glaciology, 2021 Global warming is causing glaciers in the Caucasus Mountains and around the world to lose mass at an accelerated pace. As a result of this rapid retreat, significant parts of the glacierized surface area can be covered with debris deposits, often making ...

A low-cost glacier-mapping system [PDF]
Journal of Glaciology, 2000 AbstractAn old portable 60 MHz radar has been upgraded with a new digital data-processing and -acquisition system and a new antenna construction enabling a fast and low-cost installation on a Twin Otter aircraft. Augmented by a laser altimeter and kinematic global positioning system (GPS), the system has the capability of acquiring accurate data on ...
