Join us in learning more about the impacts of climate change on navigational choke points for ships operating in the Canadian Arctic. Sea ice in the Canadian Arctic presents a significant navigational challenge for most shipping, particularly in more northerly regions and throughout the Northwest Passages. The operational risks vary depending on the Ice Class (i.e. level of ice strengthening) of the vessel and on the extent to which dynamic and mobile sea ice is prevalent and changing in the regions where shipping operates. Locations where sea ice is frequently present throughout a shipping season, impeding travel along routes that are otherwise largely ice free, have been called ‘choke points’. In this study we use a comprehensive temporal and spatial inventory of historic shipping traffic by Ice Class (1990-2018) to examine the location of choke points in the Canadian Arctic, how they’re changing over time, and how the strength of ships navigating through these locations is evolving.

Please note this webinar will be offered in English.
