AbstractOver the past two to three decades, Canadian researchers have established and maintained a permafrost monitoring network to measure two key cryospheric parameters identified by the World Meteorological Organization, permafrost thermal state and active layer thickness. The Canadian network is an important contributor to the Global Terrestrial Network for Permafrost. Information generated by the network facilitates the characterization of current permafrost conditions and the detection of change and has allowed the documentation of recent trends in permafrost thermal state. Essential information has been provided for understanding the impact of climate change on both natural and human systems, the development of strategies to deal with these impacts and the rationale planning of northern development.
The International Polar Year (IPY) provides the opportunity for the Canadian permafrost community and the International Permafrost Association (IPA) to conduct a well-designed global and coordinated, multi-national programme of permafrost observations in order to explore present conditions and their spatial and temporal variability. It also provides the opportunity to improve characterization of permafrost-soil-vegetation interactions and upgrade and maintain long-term monitoring networks. Canada is a key contributor to the IPA-led IPY project, the Thermal State of Permafrost (TSP). The TSP project will examine the ongoing impacts of climate change on permafrost conditions and will obtain a set of standardized permafrost temperature measurements for all Canadian sites (a snapshot) contributing to a global data set and map. In 2007, a collaborative proposal from the Geological Survey of Canada, University of Ottawa and Carleton University was successful in acquiring funding from the Canadian Government's IPY program for TSP-Canada. This funding along with additional support acquired by the principal investigators and collaborators has facilitated the establishment of new monitoring sites both prior to and during IPY. A number of new sites have been established in the western Arctic and northern Manitoba and several more are planned to increase the coverage in Nunavut.
The Canadian Permafrost Monitoring Network has to date been maintained through numerous partnerships and funding sources, including most recently IPY funding. Long-term commitment and funding are required to ensure ongoing maintenance of the network and that the IPY legacy continues into the future. This will also ensure that Canada continues to provide a leadership role in the development of Arctic observing systems and the provision of permafrost related data.
