We examine how recent increases in air temperature and precipitation, together with reductions in sea ice extent, may have affected the regional δD–δ 18 O composition of precipitation. In spring 2014, 80 snow samples were collected from six glaciers and ice caps across the Queen Elizabeth Islands, a...
