Abstract
A recent study found that between 2007-2009 the Canadian Arctic Archipelago was the largest glacial contributor to sea level rise outside of Greenland and Antarctica. Over this short three-year period the glaciers of this region lost ice at a rate of 92 +/- 12 Gt per year, a three-fold increase from the 2004-2006 rate of ice loss. In this study we place these losses into a longer-term context by providing ice loss estimates for the Canadian Arctic Archipelago for the period 1950-2011. Estimates are generated utilizing several different data sources and methods. Geodetic mass change estimates are made using digital elevation models derived from historic air photos, repeat gravity observations collected by GRACE, and ICESat, IceBridge and Airborne Topographic Mapper laser altimetry. For the Northern Canadian Arctic Archipelago, where the coverage of historic digital elevation models is poor, we determine long-term mass loss rates using a surface mass budget model and estimates of iceberg calving.
