D'Urville Island, Antarctica
D'Urville Island is an island of Antarctica. It is the northernmost island of the Joinville Island group, long, lying immediately north of Joinville Island, from which it is separated by Larsen Channel. The single island was charted in 1902 by the Swedish Antarctic Expedition under Otto Nordenskiöld, who named it for Captain Jules Dumont d'Urville, French explorer who discovered land in the Joinville Island group. Burden Passage separates D'Urville Island from Bransfield Island.

Antarctica
Antarctica () is Earth's southernmost and least-populated continent. Situated almost entirely south of the Antarctic Circle and surrounded by the Southern Ocean, it contains the geographic South Pole. Antarctica is the fifth-largest continent, being about 40% larger than Europe, and has an area of . Most of Antarctica is covered by the Antarctic ice sheet, with an average thickness of . Antarctica is, on average, the coldest, driest, and windiest of the continents, and it has the highest average elevation. It is mainly a polar desert, with annual precipitation of over along the coast and far less inland. About 70% of the world's freshwater reserves are frozen in Antarctica, which, if melted, would raise global sea levels by almost . Antarctica holds the record for the lowest measured temperature on Earth, . The coastal regions can reach temperatures over in summer. Native species of animals include mites, nematodes, penguins, seals and tardigrades. Where vegetation o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Scientific Committee On Antarctic Research
The Scientific Committee on Antarctic Research (SCAR) is an interdisciplinary body of the International Science Council (ISC). SCAR coordinates international scientific research efforts in Antarctica, including the Southern Ocean. SCAR's scientific work is administered through several discipline-themed ''science groups''. The organisation has observer status at, and provides independent advice to Antarctic Treaty Consultative Meetings, and also provides information to other international bodies such as the Intergovernmental Panel on Climate Change (IPCC) and the United Nations Framework Convention on Climate Change (UNFCCC). History At the International Council of Scientific Unions (ICSU)’s Antarctic meeting held in Stockholm from 9–11 September 1957, it was agreed that a committee should be created to oversee scientific research in Antarctica. At the time there were 12 nations actively conducting Antarctic research and they were each invited to nominate one delegate to ...

Bransfield Island
Bransfield Island is an island nearly long, lying southwest of D'Urville Island off the northeast end of the Antarctic Peninsula. The name "Point Bransfield", after Edward Bransfield, Master, Royal Navy, was given in 1842 by a British expedition under James Clark Ross to the low western termination of what is now the Joinville Island group. A 1947 survey by the Falkland Islands Dependencies Survey determined that this western termination is a separate island. This is one of several Antarctic islands around the peninsula known as Graham Land, which is closer to South America South America is a continent entirely in the Western Hemisphere and mostly in the Southern Hemisphere, with a relatively small portion in the Northern Hemisphere at the northern tip of the continent. It can also be described as the sout ... than any other part of that continent. Burden Passage separates Bransfield Island from D'Urville Island. See also * Knobble Head, a feature of Bransfield ...

Explorer
Exploration refers to the historical practice of discovering remote lands. It is studied by geographers and historians. Two major eras of exploration occurred in human history: one of convergence, and one of divergence. The first, covering most of ''Homo sapiens'' history, saw humans moving out of Africa, settling in new lands, and developing distinct cultures in relative isolation. Early explorers settled in Europe and Asia; 14,000 years ago, some crossed the Ice Age land bridge from Siberia to Alaska, and moved southbound to settle in the Americas. For the most part, these cultures were ignorant of each other's existence. The second period of exploration, occurring over the last 10,000 years, saw increased cross-cultural exchange through trade and exploration, and marked a new era of cultural intermingling, and more recently, convergence. Early writings about exploration date back to the 4th millennium B.C. in ancient Egypt. One of the earliest and most impactful thinkers of ...

Jules Dumont D'Urville
Jules Sébastien César Dumont d'Urville (; 23 May 1790 – 8 May 1842) was a French explorer and naval officer who explored the south and western Pacific, Australia, New Zealand, and Antarctica. As a botanist and cartographer, he gave his name to several seaweeds, plants and shrubs, and places such as d'Urville Island in New Zealand. Childhood Dumont was born at Condé-sur-Noireau in Lower Normandy. His father, Gabriel Charles François Dumont, sieur d’Urville (1728–1796), Bailiff of Condé-sur-Noireau, was, like his ancestors, responsible to the court of Condé. His mother Jeanne Françoise Victoire Julie (1754–1832) came from Croisilles, Calvados, and was a rigid and formal woman from an ancient family of the rural nobility of Lower Normandy. The child was weak and often sickly. After the death of his father when he was six, his mother's brother, the Abbot of Croisilles, played the part of his father and from 1798 took charge of his education. The Abbot taugh ...

Captain (naval)
Captain is the name most often given in English-speaking navies to the rank corresponding to command of the largest ships. The rank is equal to the army rank of colonel and air force rank of group captain. Equivalent ranks worldwide include ship-of-the-line captain (e.g. France, Argentina, Spain), captain of sea and war (e.g. Brazil, Portugal), captain at sea (e.g. Germany, Netherlands) and " captain of the first rank" (Russia). The NATO rank code is OF-5, although the United States of America uses the code O-6 for the equivalent rank (as it does for all OF-5 ranks). Four of the uniformed services of the United States — the United States Navy, United States Coast Guard, United States Public Health Service Commissioned Corps, and National Oceanic and Atmospheric Administration Commissioned Officer Corps — use the rank. Etiquette Any naval officer who commands a ship is addressed by naval custom as "captain" while aboard in command, regardless of their actual rank, even ...
