Snowcover and snowmelt measurements in High Arctic wetland, Bathurst Island

End-of-winter snowcover measurements were made in late May 2009. Snow depth and density measurements were made across a number of terrain units. In the northern section of the pass; ponds, late-lying snowbeds, wet meadow, hilltop plateau, frost cracks, lakes, and stream valleys were surveyed. In the southern portion a pond, late-lying snowbed and stream valley were measured. The snow survey also extended to the east and west of Polar Bear Pass and three ponds of various sizes were surveyed for depth and density here. In addition, snow pits were dug in the northern portion of the pass to determine snow temperature and end-of-winter cold content of the snowpack. Direct measurements of daily snowmelt were taken at four representative terrains: a pond, late-lying snowbed, wet meadow and plateau. Small portable temperature sensors were used to track temperature changes which would indicate snowpack ripening and melt at the more remote locations in the south pond, late-lying snowbed and stream valley. Automatic Weather Stations were installed at five locations in the wetland (Northern Plateau, Northern wetland, southern wetland, eastern coastal, western coastal). Here, continuous measurements of various meteorological variables (air temperature, net radiation, solar radiation, relative humidity, wind speed and direction, precipitation, ground heat, and snow temperature) were recorded. This data will be utilized in a physically based snowmelt model.
