| Popis | In this contribution, we tried to examine whether JRI glaciers could respond to climate variability in such a short time. We analysed annual mass balance changes of four dominant land-based glaciers in the northern part of JRI (Davies Dome, Whisky Glacier, Triangular Glacier, San Jose Glacier). The surface mass-balance changes were estimated based on ablation stakes and differential GNSS measurements, which were carried out over last two years (2015/16–2016/17). In addition, surface elevation changes were determined for this period and compared with digital elevation models (DEMs) created from available TanDEM-X scenes. The annual surface mass-balance was negative for the most of investigated glaciers in the 2015–17 period. One of the highest negative mass-balance was found for Whisky Glacier in 2015–16, when this glacier lost 0.36 m w.e. in average. |
