Jason (ROV)
''Jason'' is a two-body remotely operated vehicle (ROV) designed, built, and operated by the National Deep Submergence Laboratory of the Woods Hole Oceanographic Institution (WHOI). Construction of ''Jason'' began in 1982 and was first launched in 1988, redesigned in 2002 as the second iteration of the ROV (''Jason II''). The ROV allows scientists and explorers to have access to the seafloor without leaving the deck of a ship. As of 2020, ''Jason'' has completed 147 cruises with over 1200 dives and over 16,000 hours of dive time. Construction and Equipment Development on ''Jason/Medea'' began in 1982, with the goal of removing constraints of human operated vehicles such as ''Alvin''. ''Alvin'' only had 3-4 hours of time on the seafloor, required extensive and expensive planning for safety purposes, and required a sophisticated handling system for such a large vehicle. ''Jasons original commission was in 1988, with a deployment at Hood Canal in Washington state, USA. The first ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Remotely Operated Vehicle
A remotely operated underwater vehicle (technically ROUV or just ROV) is a tethered underwater mobile device, commonly called ''underwater robot''. Definition This meaning is different from remote control vehicles operating on land or in the air. ROVs are unoccupied, usually highly maneuverable, and operated by a crew either aboard a vessel/floating platform or on proximate land. They are common in deepwater industries such as offshore hydrocarbon extraction. They are linked to a host ship by a neutrally buoyant tether or, often when working in rough conditions or in deeper water, a load-carrying umbilical cable is used along with a tether management system (TMS). The TMS is either a garage-like device which contains the ROV during lowering through the splash zone or, on larger work-class ROVs, a separate assembly which sits on top of the ROV. The purpose of the TMS is to lengthen and shorten the tether so the effect of cable drag where there are underwater currents is minim ...

Jason Jr
Jason ( ; ) was an ancient Greek mythological hero and leader of the Argonauts, whose quest for the Golden Fleece featured in Greek literature. He was the son of Aeson, the rightful king of Iolcos. He was married to the sorceress Medea. He was also the great-grandson of the messenger god Hermes, through his mother's side. Jason appeared in various literary works in the classical world of Greece and Rome, including the epic poem ''Argonautica'' and the tragedy ''Medea''. In the modern world, Jason has emerged as a character in various adaptations of his myths, such as the 1963 film '' Jason and the Argonauts'' and the 2000 TV miniseries of the same name. Persecution by Pelias Pelias (Aeson's half-brother) was power-hungry and sought to gain dominion over all of Thessaly. Pelias was the progeny of a union between their shared mother, Tyro ("high born Tyro"), the daughter of Salmoneus, and the sea god Poseidon. In a bitter feud, he overthrew Aeson (the rightful king), killing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Robotic Submarines
Robotics is an interdisciplinary branch of computer science and engineering. Robotics involves design, construction, operation, and use of robots. The goal of robotics is to design machines that can help and assist humans. Robotics integrates fields of mechanical engineering, electrical engineering, information engineering, mechatronics, electronics, bioengineering, computer engineering, control engineering, software engineering, mathematics, etc. Robotics develops machines that can substitute for humans and replicate human actions. Robots can be used in many situations for many purposes, but today many are used in dangerous environments (including inspection of radioactive materials, bomb detection and deactivation), manufacturing processes, or where humans cannot survive (e.g. in space, underwater, in high heat, and clean up and containment of hazardous materials and radiation). Robots can take any form, but some are made to resemble humans in appearance. This is claimed t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Axial Seamount
Axial Seamount (also Coaxial Seamount or Axial Volcano) is a seamount and submarine volcano in the Pacific Ocean, located on the Juan de Fuca Ridge, approximately west of Cannon Beach, Oregon. Standing high, Axial Seamount is the youngest volcano and current eruptive center of the Cobb–Eickelberg Seamount chain. Located at the center of both a geological hotspot and a mid-ocean ridge, the seamount is geologically complex, and its origins are still poorly understood. Axial Seamount is set on a long, low-lying plateau, with two large rift zones trending to the northeast and southwest of its center. The volcano features an unusual rectangular caldera, and its flanks are pockmarked by fissures, vents, sheet flows, and pit craters up to deep; its geology is further complicated by its intersection with several smaller seamounts surrounding it. Axial Seamount was first detected in the 1970s by satellite altimetry, and mapped and explored by ''Pisces IV'', ''DSV Alvin'', and ...

West Mata
West Mata, located in the far northern portion of Tonga, is an active submarine volcano. Known for the deepest recorded volcanic eruption to date, West Mata does not have a very long recorded history since it was recently discovered in 2008 along with another group of volcanoes nearby. Compared to the other Mata group volcanoes, West Mata is the most hydrothermally active one and its' activity is not disputed. Geography West Mata can be found in the northeastern portion of Tonga, in between Fiji and Samoa. It is located approximately southwest of the Samoan Islands and around northeast of the Lau Islands of Fiji. Structure With data from bathymetric surveys, the structure of the West Mata volcano was made more clear. The West Mata vent has a common structure with most volcanic structures in the area, mostly dominated by a prominent rift zone that extends away from the summit, which is the peak of a conical structure with a circular base on the seafloor. Therefore, meanwhile th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

RMS Titanic
RMS ''Titanic'' was a British passenger liner, operated by the White Star Line, which sank in the North Atlantic Ocean on 15 April 1912 after striking an iceberg during her maiden voyage from Southampton, England, to New York City, United States. Of the estimated 2,224 passengers and crew aboard, more than 1,500 died, making it the deadliest sinking of a single ship up to that time. It remains the deadliest peacetime sinking of a superliner or cruise ship. The disaster drew public attention, provided foundational material for the disaster film genre, and has inspired many artistic works. RMS ''Titanic'' was the largest ship afloat at the time she entered service and the second of three s operated by the White Star Line. She was built by the Harland and Wolff shipyard in Belfast. Thomas Andrews, the chief naval architect of the shipyard, died in the disaster. ''Titanic'' was under the command of Captain Edward Smith, who went down with the ship. The ocean liner ...

A-frame
An A-frame is a basic structure designed to bear a load in a lightweight economical manner. The simplest form of an A-frame is two similarly sized beams, arranged in an angle of 45 degrees or less, attached at the top, like an uppercase letter 'A'. These materials are often wooden or steel beams attached at the top by rope, welding, gluing, or riveting. A-frames can be used as-is, as part of shears, or set up in a row along a longitudinal beam for added stability, as in a saw horse. More complex structures will often have crossmembers connecting the A-frames at different angles,"A-frame" (2009). ''Oxford English Dictionary'' Second Edition on CD-ROM (v. 4.0).

Umbilical Cable
An umbilical cable or umbilical is a cable and/or hose that supplies required consumables to an apparatus, like a rocket, or to a person, such as a diver or astronaut. It is named by analogy with an umbilical cord. An umbilical can, for example, supply air and power to a pressure suit or hydraulic power, electrical power and fiber optics to subsea equipment and divers. Spaceflight applications Rockets Umbilicals connect a missile or space vehicle to ground support equipment on the launch pad before launch. Cables carry electrical power, communications, and telemetry, and pipes or hoses carry liquid propellants, cryogenic fluids, and pressurizing and purge gases. These are automatically disconnected shortly before or at launch. Umbilical connections are also used between rocket stages, and between the rocket and its spacecraft payload; these umbilicals are disconnected as stages are disconnected and discarded. Space suits Early space suits used in Project Gemini in 1965 a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
