The Canadian Cryospheric Information Network (CCIN) and the Polar Data Catalogue (PDC) have been developed over the past two decades through collaborative partnerships between the University of Waterloo and numerous government, university, and private organizations to provide the data and information management infrastructure for the Canadian cryospheric community. The PDC is one of Canada’s primary online sources for data and information about the Arctic and is Canada's National Antarctica Data Centre. With over 2,500 metadata descriptions of projects and datasets and almost 3 million data files, the PDC contains data on physical, social, and health science and other research in Canada and globally, including significant collections from the ArcticNet Network of Centres of Excellence, the Government of Canada's International Polar Year, satellite imagery from the RADARSAT-1 and RADARSAT-2 missions, and hundreds of metadata from the Circumpolar Biodiversity Monitoring Programme, among many others. The PDC is the 100th member of the World Data System with certification as a Trusted Digital Repository, and committed to supporting polar research data management and growing in capacity. Read more.
