PERISCOP
The PERISCOP is a pressurized recovery device designed for retrieving deep-sea marine life at depths exceeding 2,000 metres. The device was designed by Bruce Shillito and Gerard Hamel at the Universite Pierre et Marie Curie. The name is an acronym for the French phrase ''Projet d’Enceinte de Remontée Isobare Servant la Capture d’Organismes Profonds'' ("Enclosure project for isobaric ascent serving to capture deep organisms"). History The PERISCOP is a unique pressurized recovery devices that contains three chambers – one for capture, one for recovery under exterior pressure, and one for transfer to the laboratory while maintaining pressure. Previous recovery devices used one chamber for all purposes. An arm designed to capture samples by force of suction is attached to the device. During ascent, pressure is maintained within the chamber by use of pressurized water. Upon surfacing, samples can be observed, filmed, and/or photographed through transparent view ports in the devic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Universite Pierre Et Marie Curie
Pierre and Marie Curie University (french: link=no, Université Pierre-et-Marie-Curie, UPMC), also known as Paris 6, was a public university, public research university in Paris, France, from 1971 to 2017. The university was located on the Jussieu Campus in the Latin Quarter of the 5th arrondissement of Paris, France. UPMC merged with Paris-Sorbonne University into a new combined Sorbonne University. It was ranked as the best university in France in medicine and health sciences by ''Times Higher Education'' in 2018. History Paris VI was one of the inheritors of the faculty of Sciences of the University of Paris, which was divided into several universities in 1970 after the student protests of May 1968 events in France, May 1968. In 1971, the five faculties of the former University of Paris (Paris VI as the Faculty of Sciences) were split and then re-formed into thirteen universities by the Edgar Faure, Faure Law. The campus of Paris VI was built in the 1950s and 1960s, on a s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acronym
An acronym is a word or name formed from the initial components of a longer name or phrase. Acronyms are usually formed from the initial letters of words, as in ''NATO'' (''North Atlantic Treaty Organization''), but sometimes use syllables, as in ''Benelux'' (short for ''Belgium, the Netherlands, and Luxembourg''). They can also be a mixture, as in ''radar'' (''Radio Detection And Ranging''). Acronyms can be pronounced as words, like ''NASA'' and ''UNESCO''; as individual letters, like ''FBI'', ''TNT'', and ''ATM''; or as both letters and words, like '' JPEG'' (pronounced ') and ''IUPAC''. Some are not universally pronounced one way or the other and it depends on the speaker's preference or the context in which it is being used, such as '' SQL'' (either "sequel" or "ess-cue-el"). The broader sense of ''acronym''—the meaning of which includes terms pronounced as letters—is sometimes criticized, but it is the term's original meaning and is in common use. Dictionary and st ...

Pachycara Sp
''Pachycara'' is a genus of marine ray-finned fish Actinopterygii (; ), members of which are known as ray-finned fishes, is a class of bony fish. They comprise over 50% of living vertebrate species. The ray-finned fishes are so called because their fins are webs of skin supported by bony or hor ...es belonging to the Family (biology), family Zoarcidae, the eelpouts. The fishes in this genus are found in the Atlantic Ocean, Atlantic, Indian Ocean, Indian, Southern Ocean, Southern and Pacific Ocean. Species There are currently 29 recognized species in this genus: * ''Pachycara alepidotum'' M. Eric Anderson, M. E. Anderson & Michael Maia Mincarone, Mincarone, 2006 * ''Pachycara angeloi'' Ralf Thiel, Thiel, Thomas Kneblsberger, Kneblsberger, Terue Kihara, Kihara & Klass Gerdes, Gerdes, 2021 * ''Pachycara andersoni'' Peter Rask Møller, Møller, 2003 (Anderson's eelpout) * ''Pachycara arabica'' Møller, 2003 (Arabian eelpout) * ''Pachycara brachycephalum'' (Paul Pappenheim, Pappe ...

Hydrothermal Vent
A hydrothermal vent is a fissure on the seabed from which geothermally heated water discharges. They are commonly found near volcanically active places, areas where tectonic plates are moving apart at mid-ocean ridges, ocean basins, and hotspots. Hydrothermal deposits are rocks and mineral ore deposits formed by the action of hydrothermal vents. Hydrothermal vents exist because the earth is both geologically active and has large amounts of water on its surface and within its crust. Under the sea, they may form features called black smokers or white smokers. Relative to the majority of the deep sea, the areas around hydrothermal vents are biologically more productive, often hosting complex communities fueled by the chemicals dissolved in the vent fluids. Chemosynthetic bacteria and Archaea form the base of the food chain, supporting diverse organisms, including giant tube worms, clams, limpets and shrimp. Active hydrothermal vents are thought to exist on Jupiter's moon Europa an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mirocaris
''Mirocaris'' is a genus of shrimp associated with hydrothermal vents. Sometimes considered the only genus of the family Mirocarididae, ''Mirocaris'' is usually placed in the family Alvinocarididae. The genus contains two species, ''M. fortunata'' and ''M. indica''; the former species ''M. keldyshi'' is now considered synonymous with ''M. fortunata''. The two species are found in different oceans, and can be distinguished by the pattern of setation on the claw of the first pereiopod. ''Mirocaris fortunata'' ''M. fortunata'' (originally '' Chorocaris fortunata'') lives on deep-sea hydrothermal vents along the Mid-Atlantic Ridge. The species' habitat ranges from ambient to warm seawater () at depths from . ''M. fortunata'' specimens have a carapace length from 3.8mm to 9.4mm long and are 12.0mm to 33.1mm long from tail to antennae tip. ''M. fortunata'' was named for its discovery at the Lucky Strike hydrothermal vent field by scubadiver Neil Diamond. ''Mirocaris indica'' ''M. ind ...

Alvinocarididae
Alvinocarididae is a family of shrimp, originally described by M. L. Christoffersen in 1986 from samples collected by DSV ''Alvin'', from which they derive their name. Shrimp of the family Alvinocarididae generally inhabit deep sea hydrothermal vent regions, and hydrocarbon cold seep environments. Carotenoid pigment has been found in their bodies. The family Alvinocarididae comprises 7 extant genera. Species '' Alvinocaris'' *''Alvinocaris alexander'' Ahyong, 2009 – South Pacific Ocean, southern Kermadec ridge, Rumble V seamount (at depths of ) and Brothers Caldera (at depths of ) hydrothermal vent fields.

Deep Sea Fish
Deep-sea fish are fish that live in the darkness below the sunlit surface waters, that is below the epipelagic or photic zone of the sea. The lanternfish is, by far, the most common deep-sea fish. Other deep sea fishes include the flashlight fish, cookiecutter shark, bristlemouths, anglerfish, viperfish, and some species of eelpout. Only about 2% of known marine species inhabit the pelagic environment. This means that they live in the water column as opposed to the benthic organisms that live in or on the sea floor. Deep-sea organisms generally inhabit bathypelagic (1000–4000m deep) and abyssopelagic (4000–6000m deep) zones. However, characteristics of deep-sea organisms, such as bioluminescence can be seen in the mesopelagic (200–1000m deep) zone as well. The mesopelagic zone is the disphotic zone, meaning light there is minimal but still measurable. The oxygen minimum layer exists somewhere between a depth of 700m and 1000m deep depending on the place in the ocean. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marine Organisms
Marine life, sea life, or ocean life is the aquatic plant, plants, aquatic animal, animals and other organisms that live in the seawater, salt water of seas or oceans, or the brackish water of coastal estuary, estuaries. At a fundamental level, marine life affects the nature of the planet. Marine organisms, mostly marine microorganisms, microorganisms, oxygen cycle, produce oxygen and biosequestration, sequester carbon. Marine life in part shape and protect shorelines, and some marine organisms even help create new land (e.g. coral building coral reef, reefs). Most life forms evolved initially in marine habitats. By volume, oceans provide about 90% of the living space on the planet. The earliest vertebrates appeared in the form of fish, which live exclusively in water. Some of these evolved into amphibians, which spend portions of their lives in water and portions on land. One group of amphibians evolved into reptiles and mammals and a few subsets of each returned to the ocean ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oceanography
Oceanography (), also known as oceanology and ocean science, is the scientific study of the oceans. It is an Earth science, which covers a wide range of topics, including ecosystem dynamics; ocean currents, waves, and geophysical fluid dynamics; plate tectonics and the geology of the sea floor; and fluxes of various chemical substances and physical properties within the ocean and across its boundaries. These diverse topics reflect multiple disciplines that oceanographers utilize to glean further knowledge of the world ocean, including astronomy, biology, chemistry, climatology, geography, geology, hydrology, meteorology and physics. Paleoceanography studies the history of the oceans in the geologic past. An oceanographer is a person who studies many matters concerned with oceans, including marine geology, physics, chemistry and biology. History Early history Humans first acquired knowledge of the waves and currents of the seas and oceans in pre-historic times. Observations ...
