British Arctic Expedition
The British Arctic Expedition of 1875–1876, led by Sir George Strong Nares, was sent by the British Admiralty to attempt to reach the North Pole via Smith Sound. Although the expedition failed to reach the North Pole, the coasts of Greenland and Ellesmere Island were extensively explored and large amounts of scientific data were collected. History Two ships, and —captained by Henry Frederick Stephenson—sailed from Portsmouth on 29 May 1875. On this expedition, Nares became the first explorer to take his ships all the way north through the channel between Greenland and Ellesmere Island —now named Nares Strait in his honour— to the Lincoln Sea. Up to this time, it had been a popular theory that this route would lead to the supposed Open Polar Sea, an ice-free region surrounding the pole, but Nares found only a wasteland of ice. A sledging party under Commander Albert Hastings Markham set a new record, Farthest North of 83° 20′ 26″ N. Meanwhile ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Scurvy
Scurvy is a disease resulting from a lack of vitamin C (ascorbic acid). Early symptoms of deficiency include weakness, feeling tired and sore arms and legs. Without treatment, decreased red blood cells, gum disease, changes to hair, and bleeding from the skin may occur. As scurvy worsens there can be poor wound healing, personality changes, and finally death from infection or bleeding. It takes at least a month of little to no vitamin C in the diet before symptoms occur. In modern times, scurvy occurs most commonly in people with mental disorders, unusual eating habits, alcoholism, and older people who live alone. Other risk factors include intestinal malabsorption and dialysis. While many animals produce their own vitamin C, humans and a few others do not. Vitamin C is required to make the building blocks for collagen. Diagnosis is typically based on physical signs, X-rays, and improvement after treatment. Treatment is with vitamin C supplements taken by mouth. Improvemen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Repulse Harbour
Repulse Harbour ( da, Repulse Havn) is a bay in northern Greenland. To the northwest it opens into the Lincoln Sea.GoogleEarth Administratively it is a part of the Northeast Greenland National Park. History The bay was named in September 1871 by Captain Hall during the Polaris expedition. Hall was looking for a wintering harbor and pushed northward with his ship after checking the bay, but could not go beyond 82° 10′ latitude on account of the ice and returned. Hall examined the bay again but found it unsuitable for wintering. There is a large cairn standing on one of the entrance points of the bay that was erected in April 1876 by senior Lieutenant Lewis Beaumont of the British Arctic Expedition. Lieutenant Beaumont's dogsled party were sent out by Captain Nares to explore the north coast of Greenland, having set out from Discovery Harbour on the Ellesmere Island side of the Robeson Channel. When the party returned to Repulse Harbour its members were severely ill with scu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Markham Ice Shelf
The Markham Ice Shelf was one of five major ice shelves in Canada, all on the north coast of Ellesmere Island, Nunavut. The ice shelf broke off from the coast in early August 2008, becoming adrift in the Arctic Ocean. The 4,500-year-old ice shelf was then in size, nearly the size of Manhattan, and approximately ten stories tall. On September 3, 2008, CNN quoted Derek Mueller, of Trent University in Ontario, Canada as saying to the Associated Press: According to images from NASA, the ice shelf completely disintegrated over a period of 6 days in August 2008. By 2015, it had completely melted. The ice shelf was named for Albert Hastings Markham Admiral Sir Albert Hastings Markham (11 November 1841 – 28 October 1918) was a British explorer, author, and officer in the Royal Navy. In 1903 he was invested as a Knight Commander of the Order of the Bath. He is also remembered for desig ..., a British Arctic explorer. Further reading * Vincent, W. F., Mueller, D. R., & Bonill ...

Ayles Ice Shelf
The Ayles Ice Shelf was one of six major ice shelves in Canada, all on the north coast of Ellesmere Island, Nunavut. The ice shelf broke off from the coast on August 13, 2005, forming a giant ice island thick and measuring around in size (approximately in area or in volume). The oldest ice in the ice shelf is believed to be over 3,000 years old. The ice shelf was at (), approximately south of the North Pole. The Ayles Ice Shelf, like the nearby Mount Ayles, was named for the Arctic explorer, Adam Ayles, who served under George Nares as the Petty Officer of HMS ''Alert'' in the British Arctic Expedition. A 1986 survey of Canadian ice shelves found that , a volume of , of ice calved from the Milne and Ayles ice shelves between 1959 and 1974. Canada lost 94% of its overall ice shelf area between 1906 and 2015. Ayles Ice Island On August 13, 2005, the entire shelf broke clear from the coast of Ellesmere, forming a new ice island.
