McClure Strait,

arm of the Beaufort Sea, c.170 mi (270 km) long and 60 mi (100 km) wide, Northwest Territories, Canada. It extends W from Viscount Melville Sound, between Melville and Eglinton islands on the north and Banks Island on the south. In 1954, U.S. icebreakers cut through the strait for the first time, opening the last obstacle to the shortest water route across the Canadian arctic region.

Areas near the edges of the CAA, including the periphery of the Western High Arctic, Amundsen Gulf, M'Clure Strait, Lancaster Sound, Prince Regent Inlet and the Gulf of Boothia, were land fast for the shortest amount of time each year (Fig.
Significant negative trends in landfast sea-ice duration also occurred in the eastern half of M'Clure Strait where landfast sea ice occurred each year (Fig.
Landfast sea-ice onset is spatially and temporally variable; by the end of January, much of the sea ice in the central archipelago is landfast, while areas on the periphery of the CAA, like Amundsen Gulf and M'Clure Strait in the west and eastern Parry Channel and Prince Regent in the east, remain mobile for the duration of some years.
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.
In 2001, the Kapitan Khlebnikov traversed route 1, the northerly route through Viscount Melville Sound, M'Clure Strait and into the Beaufort Sea, in both easterly and westerly directions.
The most direct route through the Northwest Passage is via Viscount Melville Sound into the M'Clure Strait and around the coast of Banks Island.
In the chronology of Banks Island, ice last filled M'Clure Strait in the M'Clure Stade (the penultimate stade) of Early Wisconsinan age of the Amundsen Glaciation (the last glaciation) (Hodgson et al.
They spent much of their time offshore, near or beyond the shelf break and in the polar pack ice of the estuary, or in Amundsen Gulf, M'Clure Strait, and Viscount Melville Sound.
Amundsen Gulf, M'Clure Strait, and Viscount Melville Sound are comparatively deep bodies of water (maximum depths = ca.
In the west, the highest dwell-times were in the Mackenzie Estuary and within a deep trench located within M'Clure Strait and Viscount Melville Sound.
Belugas from the Mackenzie Estuary use deep offshore areas on their way to M'Clure Strait rather than using the shallower waters near Banks Island (cf.
