Hudson Bay, Hudson Strait, and the shipping corridor to the Port of Churchill. Hudson Bay, Hudson Strait, and Foxe Basin in the eastern Canadian Arctic are shown. The shipping corridor to the Port of Churchill is indicated with colored squares, subdivided into three sections for analysis: “Hudson Bay” (blue), “Hudson Strait” (red), and “Hudson Islands” (green), which is bordered by Nottingham, Southampton, Coats, and Mansel islands. Both the Hudson Bay and Hudson Islands sections fall within the traditional boundaries of Hudson Bay. Black dots indicate the location of communities in the area.
