Mass balance of ice caps in the Queen Elizabeth Islands, Arctic Canada: M183-2/8223E-PDF
"This open file reports on the in-situ glacier mass balance surveys conducted by Natural Resources Canada across 4 ice caps (Meighen, Melville, Agassiz, and Devon ice caps) in the Canadian Arctic as part of an ongoing monitoring program to assess climatic conditions (ie. snow accumulation and summer melting) and freshwater fluxes to the ocean originating from glacier sources across this region. Results from the 2016 surveys indicate that basin-wide balances for the Meighen, Melville, and Devon ice caps 4-6 times more negative than the long-term average. A ~300 m increase of the Equilibrium Line Altitude across the Agassiz ice cap relative to the long-term mean similarly reflects unusual warming, particularly at high elevations across this region. After the relatively cool summers of 2013 and 2014, extremely negative mass balance values for 2014-2015 indicate a return to the post-2005 conditions during which time melt rates have been higher across the Canadian high Arctic than in several millennia"--Summary provided by publisher.
