Livingston Island
Livingston Island (Russian name ''Smolensk'', ) is an Antarctic island in the Southern Ocean, part of the South Shetland Islands, South Shetlands Archipelago, a group of List of Antarctic and subantarctic islands, Antarctic islands north of the Antarctic Peninsula. It was the first land discovered south of 60° south latitude in 1819, a historic event that marked the end of a centuries-long pursuit of the mythical Terra Australis, ''Terra Australis Incognita'' and the beginning of the exploration and utilization of real Antarctica. The name Livingston, although of unknown derivation, has been well established in international usage since the early 1820s. Geography Livingston Island is situated in West Antarctica, northwest of Cape Roquemaurel on the Antarctic mainland, south-southeast of Cape Horn in South America, southeast of the Diego Ramírez Islands (the southernmost land of South America), due south of the Falkland Islands, southwest of South Georgia Islands, and fr ...

René Laennec
René-Théophile-Hyacinthe Laennec (; 17 February 1781 – 13 August 1826) was a French physician and musician. His skill at carving his own wooden flutes led him to invent the stethoscope in 1816, while working at the Hôpital Necker. He pioneered its use in diagnosing various thorax, chest conditions. He became a lecturer at the in 1822 and professor of medicine in 1823. His final appointments were that of head of the medical clinic at the Hôpital de la Charité and professor at the Collège de France. He went into a coma and subsequently died of tuberculosis on 13 August 1826, at age 45. Early life Laennec was born in Quimper, Brittany, Quimper (Brittany). His mother died of tuberculosis when he was five years old, and he went to live with his great-uncle the Abbé Laennec (a priest). As a child, Laennec became ill with fatigue (medical), lassitude and repeated instances of fever, pyrexia. Laennec was also thought to have asthma. At the age of twelve, he proc ...

George Bellas Greenough
George Bellas Greenough FRS FGS (18 January 1778 – 2 April 1855) was a pioneering English geologist. He is best known as a synthesizer of geology rather than as an original researcher. Trained as a lawyer, he was a talented speaker and his annual addresses as founding president of the Geological Society of London were influential in identifying and guiding contemporary geological research. He also courted controversy, after using his presidential address in 1834 to cast aspersions on a paper on great earthquakes by Maria Graham. Greenough advocated an empirical approach to the early science; his scepticism of theoretical thinking courted controversy amongst some contemporaries, especially his doubts of the usefulness of fossils in correlating strata. He compiled a geological map of England and Wales, published in 1820, and in the penultimate year of his life used similar methods to produce the first geological map of British India. Greenough characterised himself as follo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northwest Passage
The Northwest Passage (NWP) is the sea lane between the Atlantic and Pacific oceans through the Arctic Ocean, near the northern coast of North America via waterways through the Arctic Archipelago of Canada. 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. For centuries, European explorers, beginning with Christopher Columbus in 1492, sought a navigable passage as a possible trade route to Asia, but were blocked by North, Central, and South America; by ice, or by rough waters (e.g. Tierra del Fuego). An ice-bound northern route was discovered in 1850 by the Irish explorer Robert McClure, whose expedition completed the passage by hauling sledges. Scotsman John Rae (explorer), John Rae explo ...

Longitude
Longitude (, ) is a geographic coordinate that specifies the east- west position of a point on the surface of the Earth, or another celestial body. It is an angular measurement, usually expressed in degrees and denoted by the Greek letter lambda (λ). Meridians are imaginary semicircular lines running from pole to pole that connect points with the same longitude. The prime meridian defines 0° longitude; by convention the International Reference Meridian for the Earth passes near the Royal Observatory in Greenwich, south-east London on the island of Great Britain. Positive longitudes are east of the prime meridian, and negative ones are west. Because of the Earth's rotation, there is a close connection between longitude and time measurement. Scientifically precise local time varies with longitude: a difference of 15° longitude corresponds to a one-hour difference in local time, due to the differing position in relation to the Sun. Comparing local time to an absol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HMS Griper (1813)
HMS ''Griper'' was a of the British Royal Navy, built in 1813 by Mark Williams and John Davidson at Hythe. She participated in the 1819 expedition to the Arctic led by William Parry, made a voyage to Greenland and Norway in 1823, and took part in Parry's third expedition in 1824 as a support ship. Her crew in 1819, 1823, or 1824, qualified for the " Arctic Medal", which the Admiralty issued in 1857. She was eventually broken up in 1868. Early career ''Griper'' was commissioned in July 1813 under Commander Charles Mitchell. In February 1814 Commander Arthur M'Meekan replaced Mitchell. In 1817, ''Griper'' was at Chatham. She then underwent fitting as an exploration ship at Portsmouth between December 1818 and May 1819. Expedition to Northwest Passage (1819) Lieutenant Matthew Liddon recommissioned ''Griper'' in January 1819. She then sailed with William Edward Parry from London on 11 May 1819.''The Times (London)'', Monday, 4 December 1820, p.3 Parry commanded two 3-masted sa ...

HMS Hecla (1815)
HMS ''Hecla'' was a Royal Navy launched in 1815. Like many other bomb vessels, she was named for a volcano, in this case Hekla in southern Iceland. She served at the Bombardment of Algiers in 1816. Subsequently, she took part in three expeditions to the Arctic. She then served as a survey vessel on the coast of West Africa until she was sold in 1831. She became a merchantman and in 1834 a Greenland whaler. She was wrecked in 1840. Ship history Commander William Popham commissioned ''Hecla'' for service in the Mediterranean. ''Hecla'' saw wartime service as part of the Anglo-Dutch fleet at the bombardment of Algiers on 27 August 1816. In 1847 the Admiralty authorised the award of the Naval General Service Medal with clasp "Algiers" to all surviving claimants from the battle. Arctic exploration In early 1819 she was converted to an Arctic exploration ship and made three journeys to the Arctic in search of the Northwest Passage, and made one attempt on the North Pole, all un ...

William Edward Parry
Sir William Edward Parry (19 December 1790 – 8 July 1855) was a Royal Navy officer and explorer 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. In 1827, Parry attempted one of the earliest expeditions to the North Pole. He reached 82nd parallel north, 82° 45' N, setting a record for human exploration Farthest North that stood for nearly five decades before being surpassed at 83rd parallel north, 83° 20' N by Albert Hastings Markham in 1875. Early life Parry was born in Bath, Somerset, the son of Caleb Hillier Parry and Sarah Rigby. He was educated at King Edward's School, Bath, King Edward's School. At the age of thirteen he joined the flagship of William Cornwallis, Admiral Sir William Cornwallis in the Channel fleet as a first-class volunteer, in 1806 became a midshipman, and in 1810 received ...

Arctic
The Arctic (; . ) is the polar regions of Earth, polar region of Earth that surrounds the North Pole, lying within the Arctic Circle. The Arctic region, from the IERS Reference Meridian travelling east, consists of parts of northern Norway (Nordland, Troms, Finnmark, Svalbard and Jan Mayen), northernmost Sweden (Västerbotten, Norrbotten and Lapland (Sweden), Lappland), northern Finland (North Ostrobothnia, Kainuu and Lapland (Finland), Lappi), Russia (Murmansk Oblast, Murmansk, Siberia, Nenets Autonomous Okrug, Nenets Okrug, Novaya Zemlya), the United States (Alaska), Canada (Yukon, Northwest Territories, Nunavut), Danish Realm (Greenland), and northern Iceland (Grímsey and Kolbeinsey), along with the Arctic Ocean and adjacent seas. Land within the Arctic region has seasonally varying cryosphere, snow and ice cover, with predominantly treeless permafrost under the tundra. Arctic seas contain seasonal sea ice in many places. The Arctic region is a unique area among Earth's ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antarctic
The Antarctic (, ; commonly ) is the polar regions of Earth, polar region of Earth that surrounds the South Pole, lying within the Antarctic Circle. It is antipodes, diametrically opposite of the Arctic region around the North Pole. The Antarctic comprises the continent of Antarctica, the Kerguelen Plateau, and other list of Antarctic and Subantarctic islands, island territories located on the Antarctic Plate or south of the Antarctic Convergence. The Antarctic region includes the ice shelf, ice shelves, waters, and all the island territories in the Southern Ocean situated south of the Antarctic Convergence, a zone approximately wide and varying in latitude seasonally. The region covers some 20 percent of the Southern Hemisphere, of which 5.5 percent (14 million km2) is the surface area of the Antarctica continent itself. All of the land and ice shelf, ice shelves south of 60th parallel south, 60°S latitude are administered under the Antarctic Treaty System. Biogeograph ...
