The Hydrocarbon Impacts (HI) database is a subset of the University of Calgary's Arctic Institute of North America's Arctic Science and Technology Information System database. More than 5,100 records describe "publications and research projects about the environmental impacts, socio-economic effects and regulation of hydrocarbon exploration, development and transportation in northern Canada." Users can search by record type, keyword, subject code, geographic code, author, and year, as well as an advanced search feature to locate the information. Well designed and easy to use, the database provides those interested in this narrow subject field a helpful resource.
