Proposed developments of oil and gas in Canada's Arctic may impact severely on shorelines, wildlife and habitats, and native land uses in the coastal zone. The large scale of these projects requires prior comprehensive planning and environmental assessment at regional scales. Along with other social and environmental information, data on shore types is required. This paper describes a Canadian program of Arctic marine shore classification at regional scales. To date, 20 classes of landform association are used to map, at 1:250,000, shore types for about one-third of the Arctic islands. Applications can include the rating of sensitivity to oil spills, logistics planning for monitoring and emergency measures, site selection and habitat assessment, etc. Examples of shore classes and evaluations are given.
