The M'Clure Strait (sometimes rendered McClure Strait) is a strait on the edge of the Canadian Northwest Territories. It forms the northwestern end of the Parry Channel which extends east all the way to Baffin Bay and is thus a possible route for the Northwest Passage. The strait was named for Robert McClure, an Irish Arctic explorer serving in the Royal Navy. He was the first man to traverse the North-West Passage (by boat and sledge).

The strait connects the Beaufort Sea in the west with Viscount Melville Sound in the east. It is bounded by Prince Patrick Island, Eglinton Island and Melville Island on the north and Banks Island on the south. As the strait is chronically blocked with thick ice, it is usually impassable to ships; in 1969, the United States-registered tanker SS Manhattan was freed from the ice by a Canadian icebreaker, and forced to travel through Canadian territorial waters to complete its westward passage. Ice prevented Manhattan from going through McClure Strait so the vessel sailed through the Prince of Wales Strait. There is a dispute between Canada and the United States over the waters of the Arctic Islands, other than those within 12 mi (19 km) of shore. [1]

The M'Clure Strait became fully open (ice-free) in early August 2007, and again in August 2008. The European Space Agency reported that the Arctic's Northwest Passage opened up fully sea ice free, clearing a lane through the northern section of the historically impassable route between Europe and Asia. [2]

At 15.33Z on August 29, 2012, the purpose-built Polar Bound under the command of David Scott Cowper with Jane Maufe as crew, was the first private yacht to pass through the strait. [3] Shortly thereafter, the Hallberg-Rassy sailboat Belzebub II, with three sailors aboard, became the first sailboat to travel the route. [4]

The M'Clure Strait lies within the M'Clure Rift which forms the western end of the Parry Submarine Rift Valley. It is considered an incipient rift zone because little extensional tectonism has taken place on it and no oceanic crust occurs in the middle of the strait. [5]

Northwest Passage Sea route north of North America

The Northwest Passage (NWP) is the sea route between the Atlantic and Pacific oceans through the Arctic Ocean, along the northern coast of North America via waterways through the Canadian Arctic Archipelago. The eastern route along the Arctic coasts of Norway and Siberia is accordingly called the Northeast Passage (NEP). The various islands of the archipelago are separated from one another and from Mainland Canada by a series of Arctic waterways collectively known as the Northwest Passages or Northwestern Passages.

Victoria Island Island in Arctic Canada

Victoria Island is a large island in the Arctic Archipelago that straddles the boundary between Nunavut and the Northwest Territories of Canada. It is the eighth largest island in the world, and at 217,291 km2 (83,897 sq mi) in area, it is Canada's second largest island. It is nearly double the size of Newfoundland (111,390 km2 [43,008 sq mi]), and is slightly larger than the island of Great Britain (209,331 km2 [80,823 sq mi]) but smaller than Honshu (225,800 km2 [87,182 sq mi]). The western third of the island lies in the Inuvik Region of the Northwest Territories; the remainder is part of Nunavut's Kitikmeot Region.

Banks Island Island in the Northwest Territories, Canada

Banks Island is one of the larger members of the Arctic Archipelago. Situated in the Inuvik Region, and part of the Inuvialuit Settlement Region, of the Northwest Territories, it is separated from Victoria Island to its east by the Prince of Wales Strait and from the mainland by Amundsen Gulf to its south. The Beaufort Sea lies to its west, and to its northeast M'Clure Strait separates the island from Prince Patrick Island and Melville Island.

Northeast Passage Shipping lane from the Kara Sea to the Pacific Ocean

The Northeast Passage is the shipping route between the Pacific and Atlantic oceans, along the Arctic coasts of Norway and Russia. The western route through the islands of Canada is accordingly called the Northwest Passage (NWP).

William Edward Parry English naval officer and Arctic explorer

Sir William Edward Parry was an Anglo-Welsh explorer of the Arctic best known for his 1819–1820 expedition through the Parry Channel, probably the most successful in the long quest for the Northwest Passage, until it was finally negotiated by Roald Amundsen in 1906.

Queen Elizabeth Islands Northernmost group of islands of the Canadian Arctic Archipelago

The Queen Elizabeth Islands are the northernmost cluster of islands in Canada's Arctic Archipelago, split between Nunavut and the Northwest Territories in Northern Canada. The Queen Elizabeth Islands contain approximately 14% of the global glacier and ice cap area.

Henry Larsen (explorer) 20th-century Canadian Arctic explorer

Henry Asbjørn Larsen was a Canadian Arctic explorer. Larsen was born on a small island, Herføl, south of Fredrikstad in Norway. Like his hero, Roald Amundsen, he became a seaman. Larsen immigrated to Canada, and became a British subject in 1927. In 1928, he joined the Royal Canadian Mounted Police (RCMP).

Prince of Wales Strait Strait in the Northwest Territories of Canada

The Prince of Wales Strait is a strait in the Northwest Territories of Canada separating Banks Island to the northwest from Victoria Island to the southeast. It extends from Viscount Melville Sound in the northeast to Amundsen Gulf in the southwest. From late winter it is filled by ice that usually does not break up until August, if at all. Its namesake, Prince of Wales Island, lies over 200 mi (320 km) to the east.

Viscount Melville Sound Waterway in the Northwest Territories and Nunavut, Canada

Viscount Melville Sound is an arm of the Arctic Ocean in the Kitikmeot Region, Nunavut and the Inuvik Region, Northwest Territories, Canada. Forming part of the Parry Channel, it separates Victoria Island and Prince of Wales Island from the Queen Elizabeth Islands. East of the sound, via Barrow Strait, lies Lancaster Sound, leading into Baffin Bay; westward lies the M'Clure Strait and the Arctic Ocean/Beaufort Sea. The sound is a part of the Northwest Passage.

SS <i>Manhattan</i> (1961)

SS Manhattan was an oil tanker constructed at the Fore River Shipyard in Quincy, Massachusetts, that became the first commercial ship to cross the Northwest Passage in 1969. Having been built as an ordinary tanker in 1962, she was refitted for this voyage with an icebreaker bow in 1968–69. Registered in the United States at the time, she was the largest US merchant vessel as well as the biggest icebreaker in history.

Parry Channel Natural waterway through the central Canadian Arctic Archipelago

The Parry Channel is a natural waterway through the central Canadian Arctic Archipelago. Its eastern two-thirds lie in the territory of Nunavut, while its western third lies in the Northwest Territories. It runs east to west, connecting Baffin Bay in the east with the Beaufort Sea in the west. Its eastern end is the only practical entrance to the Northwest Passage. Its western end would be a natural exit from the archipelago were it not filled with ice. The channel separates the Queen Elizabeth Islands to the north from the rest of Nunavut.

Mercy Bay is a Canadian Arctic waterway in the Northwest Territories. It is a southern arm of M'Clure Strait on northeast Banks Island. The mouth of Castel Bay is less than 20 kilometres (12 mi) to the west. These bays are a part of Aulavik National Park.

Arctic exploration Physical exploration of the Arctic region

Arctic exploration is the physical exploration of the Arctic region of the Earth. It refers to the historical period during which mankind has explored the region north of the Arctic Circle. Historical records suggest that humankind have explored the northern extremes since 325 BC, when the ancient Greek sailor Pytheas reached a frozen sea while attempting to find a source of the metal tin. Dangerous oceans and poor weather conditions often fetter explorers attempting to reach polar regions and journeying through these perils by sight, boat, and foot has proven difficult.

McClure Arctic expedition

The McClure Arctic expedition of 1850, among numerous British search efforts to determine the fate of the Franklin's lost expedition, is distinguished as the voyage during which the Irish explorer Robert McClure became the first person to confirm and transit the Northwest Passage by a combination of sea travel and sledging.

Canadian Arctic Rift System North American geological structure

The Canadian Arctic Rift System is a major North American geological structure extending from the Labrador Sea in the southeast through Davis Strait, Baffin Bay and the Arctic Archipelago in the northwest. It consists of a series of interconnected rifts that formed during the Paleozoic, Mesozoic and Cenozoic eras. Extensional stresses along the entire length of the rift system have resulted in a variety of tectonic features, including grabens, half-grabens, basins and faults.
