Popis In order to describe a response of glaciers to climate variability, we analyse surface mass-balance, equilibrium line altitude and air temperature data from Whisky Glacier and Davies Dome in the northern part of James Ross Island on the eastern side of the AP. The surface mass-balance changes were estimated using the glaciological method based on ablation stake measurements over the seven years period (2009/10–2016/17). Our results indicate a change from surface mass loss that prevailed on James Ross Island during the late 20st century to predominantly positive surface mass balance after 2009/10. We attribute the deceleration of the mass loss and the spatial pattern of surface mass-balance distribution to the snow redistribution by wind on both glaciers rather than to temperature changes.
