1985 Polar Sea controversy

The 1985 Polar Sea controversy was a diplomatic event triggered by plans for the navigation of USCGC Polar Sea through the Northwest Passage from Greenland to Alaska without formal authorization from the Canadian government. It was the United States' position that the Northwest Passage was an international strait open to shipping and it sought only to notify Canada rather than ask for permission.
