Discovery Expedition
The ''Discovery'' Expedition of 1901–1904, known officially as the British National Antarctic Expedition, was the first official British exploration of the Antarctic regions since the voyage of James Clark Ross sixty years earlier (1839–1843). Organized on a large scale under a joint committee of the Royal Society and the Royal Geographical Society (RGS), the new expedition carried out scientific research and geographical exploration in what was then largely an untouched continent. It launched the Antarctic careers of many who would become leading figures in the Heroic Age of Antarctic Exploration, including Robert Falcon Scott who led the expedition, Ernest Shackleton, Edward Wilson, Frank Wild, Tom Crean and William Lashly. Its scientific results covered extensive ground in biology, zoology, geology, meteorology and magnetism. The expedition discovered the existence of the only snow-free Antarctic valleys, which contains the longest river of Antarctica. Further achie ...

Magnetism
Magnetism is the class of physical attributes that occur through a magnetic field, which allows objects to attract or repel each other. Because both electric currents and magnetic moments of elementary particles give rise to a magnetic field, magnetism is one of two aspects of electromagnetism. The most familiar effects occur in ferromagnetic materials, which are strongly attracted by magnetic fields and can be magnetized to become permanent magnets, producing magnetic fields themselves. Demagnetizing a magnet is also possible. Only a few substances are ferromagnetic; the most common ones are iron, cobalt, nickel, and their alloys. All substances exhibit some type of magnetism. Magnetic materials are classified according to their bulk susceptibility. Ferromagnetism is responsible for most of the effects of magnetism encountered in everyday life, but there are actually several types of magnetism. Paramagnetic substances, such as aluminium and oxygen, are weakly attracted ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ross Ice Shelf
The Ross Ice Shelf is the largest ice shelf of Antarctica (, an area of roughly and about across: about the size of France). It is several hundred metres thick. The nearly vertical ice front to the open sea is more than long, and between high above the water surface. Ninety percent of the floating ice, however, is below the water surface. Most of the Ross Ice Shelf is in the Ross Dependency claimed by New Zealand. It floats in, and covers, a large southern portion of the Ross Sea and the entire Roosevelt Island, Antarctica, Roosevelt Island located in the east of the Ross Sea. The ice shelf is named after James Clark Ross, Sir James Clark Ross, who discovered it on 28 January 1841. It was originally called "The Barrier", with various adjectives including "Great Ice Barrier", as it prevented sailing further south. Ross mapped the ice front eastward to 160° W. In 1947, the U.S. Board on Geographic Names applied the name "Ross Shelf Ice" to this feature and published it in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ross Sea
The Ross Sea is a deep bay of the Southern Ocean in Antarctica, between Victoria Land and Marie Byrd Land and within the Ross Embayment, and is the southernmost sea on Earth. It derives its name from the British explorer James Clark Ross who visited this area in 1841. To the west of the sea lies Ross Island and Victoria Land, to the east Roosevelt Island and Edward VII Peninsula in Marie Byrd Land, while the southernmost part is covered by the Ross Ice Shelf, and is about from the South Pole. Its boundaries and area have been defined by the New Zealand National Institute of Water and Atmospheric Research as having an area of . The circulation of the Ross Sea is dominated by a wind-driven ocean gyre and the flow is strongly influenced by three submarine ridges that run from southwest to northeast. The circumpolar deep water current is a relatively warm, salty and nutrient-rich water mass that flows onto the continental shelf at certain locations. The Ross Sea is covered ...

HMS Terror (1813)
HMS ''Terror'' was a specialised warship and a newly developed bomb vessel constructed for the Royal Navy in 1813. She participated in several battles of the War of 1812, including the Battle of Baltimore with the bombardment of Fort McHenry (as mentioned in The Star-Spangled Banner: "And the Rockets' red glare, the Bombs bursting in air"). She was converted into a polar exploration ship two decades later, and participated in George Back's Arctic expedition of 1836–1837, the successful Ross expedition to the Antarctic of 1839 to 1843, and Sir John Franklin's ill-fated attempt to force the Northwest Passage in 1845, during which she was lost with all hands along with . On 12 September 2016, the Arctic Research Foundation announced that the wreck of ''Terror'' had been found in Nunavut's Terror Bay, off the southwest coast of King William Island. The wreck was discovered south of the location where the ship was reported abandoned, and some from the wreck of HMS ''Erebus ...

HMS Erebus (1826)
HMS ''Erebus'' was a constructed by the Royal Navy in Pembroke dockyard, Wales, in 1826. The vessel was the second in the Royal Navy named after Erebus, the personification of darkness in Greek mythology. The 372-ton ship was armed with two mortars – one and one – and 10 guns. The ship took part in the Ross expedition of 1839–1843, and was abandoned in 1848 during the third Franklin expedition. The sunken wreck was discovered by the Canadian Victoria Strait expedition in September 2014. Ross expedition After two years' service in the Mediterranean Sea, ''Erebus'' was refitted as an exploration vessel for Antarctic service, and on 21 November 1840 – captained by James Clark Ross – she departed from Van Diemen's Land (now Tasmania) for Antarctica in company with HMS ''Terror''. In January 1841, the crews of both ships landed on Victoria Land, and proceeded to name areas of the landscape after British politicians, scientists, and acquaintances. Mount Er ...

Farthest South
Farthest South is the term for the most southerly latitudes reached by explorers before the first successful expedition to the South Pole in 1911. Significant steps on the road to the pole were the discovery of lands south of Cape Horn in 1619, Captain James Cook's crossing of the Antarctic Circle in 1773, and the earliest confirmed sightings of the Antarctic mainland in 1820. From the late 19th century onward, the quest for Farthest South latitudes became a race to reach the pole, which culminated in Roald Amundsen's success in December 1911. In the years before reaching the pole was a realistic objective, other motives drew adventurers southward. Initially, the driving force was the discovery of new trade routes between Europe and the Far East. After such routes had been established and the main geographical features of the Earth had been broadly mapped, the lure for mercantile adventurers was the great fertile continent of "Terra Australis" which, according to myth, lay hidd ...

South Pole
The South Pole, also known as the Geographic South Pole or Terrestrial South Pole, is the point in the Southern Hemisphere where the Earth's rotation, Earth's axis of rotation meets its surface. It is called the True South Pole to distinguish from the south magnetic pole. The South Pole is by definition the southernmost point on the Earth, lying antipode (geography), antipodally to the North Pole. It defines geodetic latitude 90° South, as well as the direction of true south. At the South Pole all directions point North; all lines of longitude converge there, so its longitude can be defined as any degree value. No time zone has been assigned to the South Pole, so any time can be used as the local time. Along tight latitude circles, clockwise is east and counterclockwise is west. The South Pole is at the center of the Southern Hemisphere. Situated on the continent of Antarctica, it is the site of the United States Amundsen–Scott South Pole Station, which was established in 19 ...

Transantarctic Mountains
The Transantarctic Mountains (abbreviated TAM) comprise a mountain range of uplifted rock (primarily sedimentary) in Antarctica which extends, with some interruptions, across the continent from Cape Adare in northern Victoria Land to Coats Land. These mountains divide East Antarctica and West Antarctica. They include a number of separately named mountain groups, which are often again subdivided into smaller ranges. The range was first sighted by James Clark Ross in 1841 at what was later named the Ross Ice Shelf in his honour. It was first crossed during the British National Antarctic Expedition of 1901-1904. Geography The mountain range stretches between the Ross Sea and the Weddell Sea, the entire width of Antarctica, hence the name. With a total length of about , the Transantarctic Mountains are one of the longest mountain ranges on Earth. The Antarctandes are even longer, having in common with the Transantarctic Mountains the ranges from Cape Adare to the Queen M ...

Polar Plateau
The Antarctic Plateau, Polar Plateau or King Haakon VII Plateau is a large area of East Antarctica that extends over a diameter of about , and includes the region of the geographic South Pole and the Amundsen–Scott South Pole Station. This huge continental plateau is at an average elevation of about . Exploration This plateau was first sighted in 1903 during the '' Discovery'' Expedition to the Antarctic, which was led by Robert Falcon Scott. Ernest Shackleton became the first to cross parts of this plateau in 1909 during his '' Nimrod'' Expedition, which turned back in bad weather when it had reached a point from the South Pole. Shackleton named this plateau the King Edward VII Plateau in honour of the king of the United Kingdom. In December 1911, while returning from the first journey to the South Pole, the Norwegian explorer Roald Amundsen decided to name this plateau the King Haakon VII Plateau in honour of the newly elected king of Norway. The Antarctic Plateau ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
King Edward VII Land
King Edward VII Land or King Edward VII Peninsula is a large, ice-covered peninsula which forms the northwestern extremity of Marie Byrd Land in Antarctica. The peninsula projects into the Ross Sea between Sulzberger Bay and the northeast corner of the Ross Ice Shelf, and forms part of the Ross Dependency. Edward VII Peninsula is defined by the Ross Ice Shelf on the southwest, Okuma Bay on the west, and to the east by Sulzberger Bay and the Saunders Coast, all essentially on the Ross Sea / Southern Ocean in Antarctica. The northwest extremity of the peninsula is Cape Colbeck. Edward VII Peninsula is located at . The western coast is Shirase Coast. In the north and east the Swinburne Ice Shelf is located. Edward VII Peninsula was discovered on 30 January 1902 by the British National Antarctic Expedition (BrNAE) (1901–1904) under Robert Falcon Scott, who named it King Edward VII Land for British monarchy, King Edward VII of the United Kingdom. The coastline was further explored b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
