Abstract 

Tthe results of glacier monitoring on Galindez Island and Winter Island (the Argentine Islands in the Wilhelm Archipelago, Antarctic Peninsula) in 2013-2019 are presents. The main objective of research was to determine how the volumes of glaciers changed in 2013-2019 in the course of a complex study. The materials of the Ukrainian seasonal expedition of 2013-2019 was used: terrestrial laser scanning data of 2013, 2014, 2018, terrestrial digital photography of 2013, 2014, 2018, 2019 and an unmanned aerial vehicle survey of 2019. The technique was used to determine changes in the volumes of glaciers can significantly improve both the speed and accuracy of the measurements. It included complementary processing of scanning data and digital photography of 2013-2018, and digital photography and aerial survey of 2019. Changes in the volumes of glaciers were calculated for the western  and southern parts of the glacier on Galindez Island and the southern part of the glacier on Winter Island. The results demonstrate significant changes since 2002. This is confirmed quantitatively by independent studies of the West of the peninsula. Monitoring of the dynamics of glacier volumes enables detection of climatic and glaciological changes in the Antarctic region.
