Snowmelt Monitoring. Snowmelt was monitored at a site c. 3km North-East of the Polar Continental Shelf Project (PCSP) base (74 o 43’07” N, 94 o 59’19” W), near Resolute, Cornwallis Island, in the Canadian High Arctic. The region is well within the zone of continuous permafrost, and the mean annual air temperature ( ) is o C, reaching a monthly high in July of 4.2 o C. Winter endures for 8-9 months of the year, usually from mid-September to early-June, with the main snowmelt season beginning in mid-June and lasting for as little as one week or up to 3-4 weeks. A meteorological tower was set-up on June 1 st at a FLAT site and recorded a range of atmospheric and radiation data throughout the melt season. The 2000 spring snowmelt at Resolute was fairly typical, with temperatures rising above freezing from June 7 th and sustained melt occurring after June 15 th with warmer air temperatures. Various snow data were also acquired, such as a vertical temperature profile of the snow pack; snow ablation was monitored using a snow line above the snow (to measure surface changes) and surface density measurements taken, to yield a snow ablation curve for the site. Snowmelt took approximately 29 days to complete, from the first day of above 0 o C temperatures until snow cover was completely eliminated from the FLAT site and it’s immediate vicinity (c. 1 km 2 ).
