ABSTRACT Two small glaciers on James Ross Island, the north-eastern Antarctic Peninsula, experienced surface mass gain between 2009 and 2015 as revealed by field measurements. A positive cumulative balance of 0.57 ± 0.67 0.11 0.37 m w.e. was observed during 2009–2015 period Whisky Glacier Davies Dome, respectively. The results indicate a change from loss that prevailed in region first decade 21st century to predominantly after 2009/10. spatial pattern annual mass-balance distribution implies snow redistribution wind both glaciers. mean equilibrium line altitudes for (311 16 a.s.l.)
