This report reviews the range of expected ice conditions and shipping seasons for ice-strengthened cargo vessels serving the Coronation Gulf region of Nunavut. An earlier feasibility study contracted by the Government of the Northwest Territories (GNWT) to look at shipping to Western Artic communities with deep-sea vessels, formed a baseline reference. The original historical ice database was supplemented by adding the results of recent Canadian Ice Service data on ice clearing trends (1998 to 2003), and selected Landsat 7 images available since 1999. In addition, new material was developed to reflect the present status of Arctic shipping regulations and possible long-term trends in ice severity related to climatic change.
