AbstractIn-situ glacier mass balance surveys were conducted across the Devon, Meighen, and South Melville ice caps in the Canadian high Arctic by Natural Resources Canada during spring, 2014. Survey results indicate positive net balance values for the Devon (NW) and Meighen ice caps (+2 and +17 cm w.e. respectively), while the South Melville ice cap experienced slightly negative mass balance (-18 cm w.e.). Results from these glacier surveys are indicative of relatively cool conditions that prevailed across this region during the summer of 2013. Associated water equivalent volume change for the Devon (NW), Meighen, and South Melville ice caps in 2012-2013 was 0.04, 0.01, and -0.009 Gt respectively resulted in a net negative contribution to global sea-level rise from these 3 sites for the 2012-2013 balance year.
Summary(Plain Language Summary, not published)
The Canadian high Arctic holds the single largest mass of ice outside of the Greenland and Antarctic ice sheets. Knowledge of annual glacier mass balance (ie. the difference between input[snow] and output[melt] for any given year) in this region thus provides a robust indicator of climate change, and facilitates assessments of contributions to regional and global sea-level from Canadian glaciers and ice caps. This report presents a summary of results from the 2014 glacier mass balance surveys (representing the 2012-2013 balance year) conducted by NRCan on the Devon, Melville South, and Meighen ice caps. Overall, glacier mass balance in the Queen Elizabeth Islands for 2012-2013 indicated a negative contribution to global sea-level rise reflecting relatively cool conditions that prevailed across this region during the summer of 2013.
