Bathyscape
A bathyscaphe ( or ) is a free-diving self-propelled deep-sea submersible, consisting of a crew cabin similar to a bathysphere, but suspended below a float rather than from a surface cable, as in the classic bathysphere design. The float is filled with gasoline because it is readily available, buoyant, and, for all practical purposes, incompressible. The incompressibility of the gasoline means the tanks can be very lightly constructed, since the pressure inside and outside the tanks equalises, eliminating any differential. By contrast, the crew cabin must withstand a huge pressure differential and is massively built. Buoyancy at the surface can be trimmed easily by replacing gasoline with water, which is denser. Auguste Piccard, inventor of the first bathyscaphe, composed the name ''bathyscaphe'' using the Ancient Greek words βαθύς ''bathys'' ("deep") and σκάφος ''skaphos'' ("vessel"/"ship"). Mode of operation To descend, a bathyscaphe floods air tanks with sea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

NFWO
The National Fund for Scientific Research (NFSR) (Dutch: ''Nationaal Fonds voor Wetenschappelijk Onderzoek'' (NFWO), French: ''Fonds National de la Recherche Scientifique'' (FNRS)) was once a government institution in Belgium for supporting scientific research until it was split into two separate organizations: * the Dutch-speaking '' Fonds Wetenschappelijk Onderzoek – Vlaanderen'' (FWO) (Research Foundation – Flanders) for the Flemish Community and * the French-speaking ''Fonds de la Recherche Scientifique – FNRS'' (F.R.S.–FNRS) for the French Community. The task of the FWO and F.R.S.–FNRS is to stimulate the development of new knowledge in all scientific disciplines. The means to achieve this, is to finance excellent scientists and research projects after an inter-University competition and with an evaluation by foreign experts. The criterion for support is the scientific quality of the scientist and the research proposal, irrespective of scientific discipline. Both in ...

Sole (fish)
Sole is a fish belonging to several families. Generally speaking, they are members of the family Soleidae, but, outside Europe, the name ''sole'' is also applied to various other similar flatfish, especially other members of the sole suborder Soleoidei as well as members of the flounder family. In European cookery, there are several species which may be considered ''true soles'', but the common or Dover sole ''Solea solea'', often simply called ''the sole'', is the most esteemed and most widely available. Etymology of the word The word ''sole'' in English, French, and Italian comes from its resemblance to a sandal, Latin ''solea''. In other languages, it is named for the tongue, e.g. el, γλώσσα, german: Seezunge, nl, zeetong or ', hu, nyelvhal, es, lenguado, zh, 龍脷 ("dragon tongue"), ar, لسان الثور lisan Ath-thawr (for the common sole) meaning 'the tongue of ox' in Qosbawi accent.

Diatom
A diatom (Neo-Latin ''diatoma''), "a cutting through, a severance", from el, διάτομος, diátomos, "cut in half, divided equally" from el, διατέμνω, diatémno, "to cut in twain". is any member of a large group comprising several genera of algae, specifically microalgae, found in the oceans, waterways and soils of the world. Living diatoms make up a significant portion of the Earth's biomass: they generate about 20 to 50 percent of the oxygen produced on the planet each year, take in over 6.7 billion metric tons of silicon each year from the waters in which they live, and constitute nearly half of the organic material found in the oceans. The shells of dead diatoms can reach as much as a half-mile (800 m) deep on the ocean floor, and the entire Amazon basin is fertilized annually by 27 million tons of diatom shell dust transported by transatlantic winds from the African Sahara, much of it from the Bodélé Depression, which was once made up of a system of ...

Mariana Trench
The Mariana Trench is an oceanic trench located in the western Pacific Ocean, about east of the Mariana Islands; it is the deepest oceanic trench on Earth. It is crescent-shaped and measures about in length and in width. The maximum known depth is at the southern end of a small slot-shaped valley in its floor known as the Challenger Deep. If Mount Everest were hypothetically placed into the trench at this point, its peak would still be underwater by more than . At the bottom of the trench, the water column above exerts a pressure of , more than 1,071 times the standard atmospheric pressure at sea level. At this pressure, the density of water is increased by 4.96%. The temperature at the bottom is . In 2009, the Mariana Trench was established as a US National Monument. Monothalamea have been found in the trench by Scripps Institution of Oceanography researchers at a record depth of below the sea surface. Data has also suggested that microbial life forms thrive withi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Don Walsh
Don Walsh (born November 2, 1931) is an American oceanographer, explorer and marine policy specialist. He and Jacques Piccard were aboard the bathyscaphe ''Trieste'' when it made a record maximum descent into the Challenger Deep on January 23, 1960, the deepest point of the world's oceans. The depth was measured at , but later and more accurate measurements have measured it at . Biography Walsh has been associated with ocean science, engineering, and marine policy for more than fifty years. He was commissioned as an officer in the United States Navy upon graduation from the United States Naval Academy in 1954. He attained the rank of captain by the time he retired. He spent fifteen years at sea, mostly in submarines, and was a submarine commander. He also worked with ocean-related research and development for the U.S. Navy.

Jacques Piccard
Jacques Piccard (28 July 19221 November 2008) was a Swiss oceanographer and engineer, known for having developed underwater submarines for studying ocean currents. In the Challenger Deep, he and Lt. Don Walsh of the United States Navy were the first people to explore the deepest known part of the world's ocean, and the deepest known location on the surface of Earth's crust, the Mariana Trench, located in the western North Pacific Ocean. Family life Jacques Piccard was born in Brussels, Belgium, the son of Auguste Piccard, who was himself an adventurer and engineer. Jacques' father Auguste twice beat the record for reaching the highest altitude in a balloon, during 1931–1932. The Piccard family thus had the unique distinction of breaking world records for both the highest flight and the deepest dive. * Jules Piccard (professor of chemistry) ** Auguste Piccard (physicist, aeronaut, balloonist, hydronaut) *** Jacques Piccard (hydronaut) **** Bertrand Piccard (aeronaut, ballooni ...

FNRS-3
The ''FNRS-3'' or ''FNRS III'' is a bathyscaphe of the French Navy. It is currently preserved at Toulon. She set world depth records, competing against a more refined version of her design, the ''Trieste''. The French Navy eventually replaced her with the bathyscaphe '' FNRS-4'', in the 1960s.Paine, Lincoln P. (1997). ''Ships of the World''. Houghton Mifflin. p. 188. After damage to the ''FNRS-2'' during its sea trials in 1948, the Fonds National de la Recherche Scientifique (FNRS) ran out of funding, and the submersible was sold to the French Navy, in 1950. She was subsequently substantially rebuilt and improved at Toulon naval base, and renamed ''FNRS-3''.''Encyclopædia Britannica'', 2010 Online, 9 September 2010 (accessed 9 September 2010) She was relaunched in 1953, under the command of Georges Houot, a French naval officer.

The Silent World (book)
''The Silent World'' (subtitle: ''A story of undersea discovery and adventure, by the first men to swim at record depths with the freedom of fish'') is a 1953 book co-authored by Captain Jacques-Yves Cousteau and Frédéric Dumas, and edited by James Dugan (historian), James Dugan. Background Although a French national, Cousteau wrote the book in English. Cousteau and Émile Gagnan designed, built, and tested the first "aqua-lung" in the summer of 1943, off the southern coast of France. In the opening chapters, Cousteau recounts the earliest days of scuba diving with his diving companions Frédéric Dumas and Philippe Tailliez. The aqualung allowed for the first time untethered, free-floating extended deep water diving, and ushered in the modern era of scuba diving. Later chapters include excursions diving to shipwrecks. It was the basis of the Academy Award-winning documentary ''The Silent World'' (1956). It has been very successful; as of the book's 50th anniversary, it has bee ...

Jacques Cousteau
Jacques-Yves Cousteau, (, also , ; 11 June 191025 June 1997) was a French naval officer, oceanographer, filmmaker and author. He co-invented the first successful Aqua-Lung, open-circuit SCUBA (self-contained underwater breathing apparatus). The apparatus assisted him in producing some of the first underwater documentaries. Cousteau wrote many books describing his undersea explorations. In his first book, '' The Silent World: A Story of Undersea Discovery and Adventure'', Cousteau surmised the existence of the echolocation abilities of porpoises. The book was adapted into an underwater documentary called ''The Silent World''. Co-directed by Cousteau and Louis Malle, it was one of the first films to use underwater cinematography to document the ocean depths in color. The film won the 1956 Palme d'Or at the Cannes Film Festival and remained the only documentary to do so until 2004, when '' Fahrenheit 9/11'' received the award. It was also awarded the Academy Award for Best Do ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
