Data Identification

Abstract: Field measurements were necessary to initialize, force, and validate the surface energy balance model for the Belcher Glacier. Hourly and daily averages of air temperature, relative humidity, wind speed and direction, net radiation, and surface elevation were recorded over the 2008 summer (June-September) by two automatic weather stations (AWS) on the glacier centerline at elevations of 500 m and 900 m. All instruments were installed 2 m above the surface. In August 2009, the AWSs were re-programmed to record bi-hourly and daily averages of all meteorological variables to preserve battery power and memory. The AWSs are serviced annually. A total of 25 ablation stakes were drilled into the ice in May 2008 at 100 m elevation intervals between 500 m and 1100 m, and also at 250 m spacing on lateral transects at 500 m and 900 m elevation. These stakes were surveyed weekly in the 2008 summer, and once again in the spring of 2009. Snow pits were dug twice weekly at 900 m elevation to record the temperature and density of distinct horizons within the snowpack.
Purpose: This project ultimately aimed to run a distributed surface energy balance model coupled with a sub-surface snow model to investigate spatial and temporal variations in surface melt water production on the Belcher Glacier. Detailed measurements of meteorological variables and snow surface properties were collected in the summer (June-September) of 2008 in order to initialize, force, and validate the model. The Belcher Glacier is a major outlet glacier of the Devon Island ice cap and accounts for approximately half of the iceberg calving loss from the ice cap (~15% of the total mass loss). This is a contribution to an International Polar Year (IPY) project, aiming to investigate the hypothesis that hydrologically driven changes in ice flow will increase the rate of mass loss by iceberg calving, and how these dynamics will respond to future climate warming.
