22) Between the islands lie a number of possible shipping routes connecting the Atlantic and Arctic Oceans (and later the Pacific Ocean), with the widest and deepest route running from Lancaster Sound through Barrow Strait into Viscount Melville Sound and onwards through M'Clure Strait into the Beaufort Sea.
It seems inevitable that the deeper, wider routes further north will eventually open as well, as even M'Clure Strait briefly did in September 2007 and again in September 2008.
Historically, multi-year ice from the Arctic Ocean has been pushed into M'Clure Strait at the western end of the Passage, stymieing even the SS Manhattan, a 1,005-foot long ice-strengthened super-tanker that attempted in 1969 to break through M'Clure Strait accompanied by two icebreakers.
92) American officials had therefore intended that the Manhattan would remain on the high seas throughout its voyage, entering the Passage through Lancaster Sound and exiting through M'Clure Strait at the western end.
Since Bellot Strait is less than one mile across, the addition of a gate in the Barrow Strait had the effect of forcing any vessel making the passage, including through M'Clure Strait.
