The large island at the centre of this satellite image is Victoria Island, with Banks Island top left. The Victoria Strait adjoins the east coast of Victoria Island, just above the Queen Maud Gulf which runs west to east.
The strait is wide, with almost no islands, save for the rather large Royal Geographical Society Island near the Queen Maud Gulf at the extreme south of the strait. The strait has never been comprehensively surveyed, however, charted portions indicate several patches where the water is only 10 metres (30ft) deep. Ships drawing up to 9 metres (30ft) have navigated the strait, but it is made very difficult by the ice. Most of the year the strait is covered with rough, heavy ice. Much of this is polar ice which has flowed down the M'Clintock Channel from the Viscount Melville Sound. Large-scale breakup of the ice in the strait begins by late July and continues into late September when it begins to freeze again.[2]
Near the entrance of Victoria Strait was where HMS Terror and HMS Erebus became trapped during John Franklin's expedition and were abandoned in 1848. Due to the hazards of the strait, a longer route was used which went around King William Island. This route was easier despite having an even shallower bottom.[3] In 1967, the Victoria Strait was used for the first time by an icebreaker, the CCGS John A. Macdonald, when travelling to the western Arctic to assist shipping. It was crossed again by the same icebreaker in 1975, and later in 1976 by the icebreakers CCGS Louis S. St-Laurent and CCGS J.E. Bernier.[2]
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, Northwestern Passages or the Canadian Internal Waters.
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 [43,010 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 [87,200 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. The population of 2,168 is divided among 2 settlements, the larger of which is in Nunavut and the other of which is in the Northwest Territories.
Amundsen Gulf is a gulf located mainly in the Inuvik Region, Northwest Territories, Canada with a small section in the Kitikmeot Region of Nunavut. It lies between Banks Island and Victoria Island and the mainland. It is approximately 250 mi (400 km) in length and about 93 mi (150 km) across where it meets the Beaufort Sea.
Henry Asbjørn Larsen was a Norwegian-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).
CCGS Henry Larsen is a Canadian Coast Guard Improved Pierre Radisson-class icebreaker serving in the Newfoundland and Labrador region and based in St John's, Newfoundland and Labrador. Entering service in 1988, Henry Larsen is the fourth ship and of an improved design over the rest of the ships in her class. The ship operates in the Arctic Ocean during summer months.
CCGS Terry Fox is a Canadian Coast Guard heavy icebreaker. She was originally built by Burrard-Yarrows Corporation in Canada in 1983 as part of an Arctic drilling system developed by BeauDril, the drilling subsidiary of Gulf Canada Resources. After the offshore oil exploration in the Beaufort Sea ended in the early 1990s, she was first leased and then sold to the Canadian Coast Guard.
CCGS Amundsen is a Pierre Radisson-class icebreaker and Arctic research vessel operated by the Canadian Coast Guard. The vessel entered service in 1979 as Franklin and was renamed Sir John Franklin in 1980 and served as such until 1996. Declared surplus, the vessel was used as an accommodation ship in Labrador in 1996 and placed in reserve in 2000. In 2003, the ship was reactivated and underwent conversion to an Arctic research vessel. The ship recommissioned as Amundsen.
CCGS Louis S. St-Laurent is a Canadian Coast Guard (CCG) heavy icebreaker. Louis S. St-Laurent's home port is St. John's, Newfoundland and Labrador. It is the largest icebreaker and flagship of the CCG.
The M'Clure 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.
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.
Fury and Hecla Strait is a narrow Arctic seawater channel located in the Qikiqtaaluk Region of Nunavut, Canada.
Francis Rawdon Moira Crozier was an Irish officer of the Royal Navy and polar explorer who participated in six expeditions to the Arctic and Antarctic. In May 1845, he was second-in-command to Sir John Franklin and captain of HMS Terror during the Franklin expedition to discover the Northwest Passage, which ended with the loss of all 129 crewmen in mysterious circumstances.
CCGS Des Groseilliers is a Pierre Radisson-class icebreaker in the Canadian Coast Guard. The vessel is named after Médard Chouart des Groseilliers (1618–1669) a close associate of Pierre-Esprit Radisson in explorations west of the Great Lakes and the founding of the British Hudson's Bay Company. The ship entered service in 1982. The vessel has participated in a number of research voyages, including Ice Station SHEBA. As part of the Surface Heat Budget of the Arctic Ocean experiment conducted in the Arctic Ocean from October 1997 to October 1998 to provide polar input to global climate models, Des Groseilliers was allowed to be frozen into the ice for the Arctic winter, to serve as a base for scientific researchers.
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 ice navigation during this voyage with an icebreaker bow in 1968–69. Registered in the United States at the time, she was the largest US merchant vessel. If we consider ice navigation vessels as icebreakers, then Manhattan was the biggest icebreaker in history before the construction of the Yamalmax class ships.
CCGS John A. Macdonald was a Canadian Coast Guard heavy icebreaker. She was named after The Right Honourable, Sir John Alexander Macdonald, the first Prime Minister of Canada. The ship was commissioned into the Canadian Department of Transport's Marine Service in 1960 using the prefix "Canadian Government Ship" (CGS). The vessel was transferred in 1962 into the newly created Canadian Coast Guard (CCG) and served with distinction until being decommissioned in 1991, and replaced by the then-chartered CCGS Terry Fox.
Franklin's lost expedition was a failed British voyage of Arctic exploration led by Captain Sir John Franklin that departed England in 1845 aboard two ships, HMS Erebus and HMS Terror, and was assigned to traverse the last unnavigated sections of the Northwest Passage in the Canadian Arctic and to record magnetic data to help determine whether a better understanding could aid navigation. The expedition met with disaster after both ships and their crews, a total of 129 officers and men, became icebound in Victoria Strait near King William Island in what is today the Canadian territory of Nunavut. After being icebound for more than a year Erebus and Terror were abandoned in April 1848, by which point Franklin and nearly two dozen others had died. The survivors, now led by Franklin's second-in-command, Francis Crozier, and Erebus's captain, James Fitzjames, set out for the Canadian mainland and disappeared, presumably having perished.
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.
CCGS Pierre Radisson is the lead ship of her class of icebreakers. Constructed and operated by the Canadian Coast Guard, the vessel is based at Quebec City on the Saint Lawrence River. The ship was constructed in British Columbia in the 1970s and has been in service ever since. The vessel is named for Pierre-Esprit Radisson, a 17th-century French fur trader and explorer.
Breadalbane was an 1843 British three-masted merchant barque that was crushed by ice and sank in the Arctic in 1853. Notable as one of the northernmost shipwrecks known, she is also considered one of the best-preserved wooden ships ever found in the sea due to slow deterioration in the cold Arctic water. Historically, Breadalbane is considered to be a time capsule.
The Pierre Radisson-class icebreakers, also known as R-class icebreakers, are a class of four icebreakers constructed for and operated by the Canadian Coast Guard. The Canadian Coast Guard designates the four ships in the class as medium icebreakers. Built in two phases, the first three ships, Pierre Radisson, Franklin and Des Groseilliers, were built to a common design. The fourth, Henry Larsen was built to a modified design and is considered a subclass, the Improved R-class icebreaker. Franklin was later renamed Sir John Franklin before undergoing a re-design for use primarily as an Arctic research vessel. Upon the vessel's return to service, the ship was once again renamed Amundsen. All the vessels are named for people who sailed through Canada's northern waters. The class operates in the Arctic Ocean in the summer, patrolling, icebreaking and research missions.
