White Glacier is a 14 km long alpine glacier located on Axel Heiberg Island in the northwest part of Nunavut. The glacier has a record of mass balance measurements spanning 55 years and these observations indicate that, on average, increased melt in recent years has not been offset by yearly snowfall - therefore leading to glacier retreat. White Glacier has a rich history of glacier research dating back to 1959, and these early studies provide valuable baseline of information for us to observe how Arctic glaciers are responding to climate change. Today, our research involves measuring changes to the glacier's shape and size since 1960 using air photo mapping methods and radar measurements of ice thickness. We are also monitoring ice motion throughout the year by using continuously running GPS stations installed on the glacier. Axel Heiberg Island is uninhabited except for a few months of the year when researchers undertake field studies at the McGill Arctic Research Station in Expedition Fiord. We carry out our fieldwork in the spring (April and May) when we can travel on the glacier by snowmobile, and again in July when the area is snow free and we are able to observe the effect of increased temperatures and melt on ice movement.
