Structural Basin
A structural basin is a large-scale structural formation of rock strata formed by tectonic warping of previously flat-lying strata. They are geological depressions, the inverse of domes. Elongated structural basins are also known as synclines. Some are sedimentary basins, aggregations of sediment that filled up a depression or accumulated in an area. Others were formed by tectonic events long after the sedimentary layers were deposited. Basins may appear on a geologic map as roughly circular or elliptical, with concentric layers. Because the strata dip toward the center, the exposed strata in a basin are progressively younger from the outside in, with the youngest rocks in the center. Basins are often large in areal extent, often hundreds of kilometers across. Structural basins are often important sources of coal, petroleum, and groundwater.

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 ve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

National Science Foundation
The National Science Foundation (NSF) is an independent agency of the United States government that supports fundamental research and education in all the non-medical fields of science and engineering. Its medical counterpart is the National Institutes of Health. With an annual budget of about $8.3 billion (fiscal year 2020), the NSF funds approximately 25% of all federally supported basic research conducted by the United States' colleges and universities. In some fields, such as mathematics, computer science, economics, and the social sciences, the NSF is the major source of federal backing. The NSF's director and deputy director are appointed by the President of the United States and confirmed by the United States Senate, whereas the 24 president-appointed members of the National Science Board (NSB) do not require Senate confirmation. The director and deputy director are responsible for administration, planning, budgeting and day-to-day operations of the foundation, whi ...

Technical University Of Denmark
The Technical University of Denmark ( da, Danmarks Tekniske Universitet), often simply referred to as DTU, is a polytechnic university and school of engineering. It was founded in 1829 at the initiative of Hans Christian Ørsted as Denmark's first polytechnic, and it is today ranked among Europe's leading engineering institutions. It is located in the town Kongens Lyngby, north of central Copenhagen, Denmark. Along with École Polytechnique in Paris, École Polytechnique Fédérale de Lausanne, Eindhoven University of Technology, Technical University of Munich and Technion – Israel Institute of Technology, DTU is a member of EuroTech Universities Alliance. History DTU was founded in 1829 as the "College of Advanced Technology" (Danish: Den Polytekniske Læreanstalt). The Physicist Hans Christian Ørsted, at that time a professor at the University of Copenhagen, was one of the driving forces behind this initiative. He was inspired by the École Polytechnique in Paris, Franc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
French Ship Astrolabe (1817)
''Astrolabe'' was originally a horse-transport barge converted into an exploration ship of the French Navy. Originally named ''Coquille'', she is famous for her travels with Jules Dumont d'Urville. The name derives from an early navigational instrument, the astrolabe, a precursor to the sextant. Career Voyage under the command of Louis Isidore Duperrey Louis-Isidore Duperrey commanded ''Coquille'' on its circumnavigation of the earth (1822–1825) with Jules Dumont d'Urville as second. René-Primevère Lesson also travelled on ''Coquille'' as a naval doctor and naturalist. On their return in March 1825, Lesson and Dumont brought back to France an imposing collection of animals and plants collected on the Falkland Islands, on the coasts of Chile and Peru, in the archipelagos of the Pacific and New Zealand, New Guinea and Australia. During the voyage the ship spent two weeks in the Bay of Islands in the north of New Zealand in 1824. The vessel arrived in Kosrae where Duperrey ...

Flagship
A flagship is a vessel used by the commanding officer of a group of naval ships, characteristically a flag officer entitled by custom to fly a distinguishing flag. Used more loosely, it is the lead ship in a fleet of vessels, typically the first, largest, fastest, most heavily armed, or best known. Over the years, the term "flagship" has become a metaphor used in industries such as broadcasting, automobiles, education, technology, airlines, and retail to refer to their highest profile or most expensive products and locations. Naval use In common naval use, the term ''flagship'' is fundamentally a temporary designation; the flagship is wherever the admiral's flag is being flown. However, admirals have always needed additional facilities, including a meeting room large enough to hold all the captains of the fleet and a place for the admiral's staff to make plans and draw up orders. Historically, only larger ships could accommodate such requirements. The term was also used b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
French Antarctic Expedition
The French Antarctic Expedition is any of several French expeditions in Antarctica. First expedition In 1772, Yves-Joseph de Kerguelen-Trémarec and the naturalist Jean Guillaume Bruguière sailed to the Antarctic region in search of the fabled Terra Australis. Kerguelen-Trémarec took possession of various Antarctic territories for France, including what would later be called the Kerguelen Islands. In Kerguelen-Trémarec's report to King Louis XV, he greatly overestimated the value of the Kerguelen Islands. The King sent him on a second expedition to Kerguelen in late 1773. When it became clear that these islands were desolate, useless, and not the Terra Australis, he was sent to prison. Second expedition In 1837, during an 1837–1840 expedition across the deep southern hemisphere, Captain Jules Dumont d'Urville sailed his ship ''Astrolabe'' along a coastal area of Antarctica which he later named Adélie Land, in honor of his wife. During the Antarctic part of this exp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 taug ...

Structural Basins Of Antarctica
A structure is an arrangement and organization of interrelated elements in a material object or system, or the object or system so organized. Material structures include man-made objects such as buildings and machines and natural objects such as biological organisms, minerals and chemicals. Abstract structures include data structures in computer science and musical form. Types of structure include a hierarchy (a cascade of one-to-many relationships), a network featuring many-to-many links, or a lattice featuring connections between components that are neighbors in space. Load-bearing Buildings, aircraft, skeletons, anthills, beaver dams, bridges and salt domes are all examples of load-bearing structures. The results of construction are divided into buildings and non-building structures, and make up the infrastructure of a human society. Built structures are broadly divided by their varying design approaches and standards, into categories including building structures, ar ...
