What type vehicle would scientists commonly need to be able to explore depths of the ocean?
the answer is a rovs
Why are ROVs and robots so useful?
They don't need air. They don't need food.
What is the role of science in exploration?
Almost everything to do with exploration is science based. How to get to where you want to explore requires science to overcome whatever obstacles are in your way. For instance, When Columbus first sailed across the ocean and discovered the Americas, he used scientific navigational equipment, and ships designed on the science of the day (albeit, that science has not been far surpassed) Today, our exploration is mainly pointed at the stars and the oceans. In both cases we need science to keep us alive. (We cannot survive in space or under water naturally) We also rely on science to bring us to these new areas. We have sent satellites to orbit and gather information on every planet in our solar system, and ROVs (remote operated vehicles) into depths of the oceans we cannot survive at. We've sent many astronauts into space, and divers into the oceans. All of this requires a lot of science. Biology is need to identify new animals and plants discovered. Chemistry is needed to clean the air breathed by the astronauts and recycle it. As well as for the propulsion of the space shuttles and boats. I would say every scientific discipline is required for exploration.

The cast of Sedmero krkavcu - 1993 includes: Petr Gaglik as Bruder Matej Jana Gazdikova Ivan Hora as Bruder Jura Daniel Rovs as Wind Martin Ruzek as Sun
Why are most ROVs tethered?
im trying to find the same answer bro, are you in gr 8 science?
Why are rov vehicles better than manned vehicles?
The obvious benefit to using ROVs rather than manned vehicles is first and foremost the cost. It costs a great deal more to build a vehicle large enough for a person, then you have to pay that person, who must be very skilled, to pilot the vehicle underwater. This is a much greater level of risk, therefore a greater deal of money. ROVs constitute a much reduced level of risk and cost. You can build the vehicle smaller, and the operator controls the vehicle from a relatively safe location(usually from the offshore platform, but also from onshore). The risk if anything goes wrong is just lost equipment. Although this can be quite significant, it is nothing compared to losing a human life.
Has The world's deepest known trench ever been explored?
For the most part, the deepest parts of the the oceans have not been explored. However, in 2012, James Cameron reached the bottom of Mariana Trench, the deepest part of the Pacific Ocean. When he got to the bottom he was at 35,756 feet.Ê
What was the name of the first submarine to dive to the bottom of the Mariana trench?
The Swiss-designed, Italian-built, United States Navy bathyscaphe Trieste reached the bottom at 1:06 p.m. on January 23, 1960, with U.S. Navy Lieutenant Don Walsh and Jacques Piccard on board. Only three descents have ever been achieved. The first was the manned descent by Trieste in 1960. This was followed by the unmanned ROVs Kaikō in 1996 and Nereus in 2009.
Who started the oil spill?
On the morning of April 22, 2010 (two days after the blowout accident), CNN quoted Coast Guard Petty Officer Ashley Butler as saying that "oil was leaking from the rig at the rate of about 8,000 barrels of crude per day." That afternoon, as a large oil slick spread, Coast Guard Senior Chief Petty Officer Michael O'Berry used the same figure. Two remotely operated underwater vehicles (ROVs) were sent down to attempt to cap the well, but had been unsuccessful. Butler warned of a leak of up to 700,000 US gallons of diesel fuel, and BP Vice President David Rainey termed the incident as being a potential "major spill."
What is the deep?
DeepWorkerThe DeepWorker is a submersible vessel used to explore the underwater world. Its compact and lightweight construction allows one explorer at a time to descend to depths as great as 2,000 feet. Explorers can go deeper, and spend more time below the surface than they can with traditional Scuba equipment, greatly enhancing exploration and research opportunities. The submersible is easy to operate, opening up the underwater experience to nontraditional explorers as well as experienced field scientists. Because it is a one-person system, the pilot is also the researcher, navigator, and camera operator. The sub was designed to make operation as intuitive as possible, so the pilot can devote attention to these other tasks.Vehicle SpecificationsLength8.25 ft. (2.4 m)Beam5.3 ft. (1.6 m)Height5.75 ft.

(114 kg)Life Support106 person hoursSpeed3 - 4 knots maxAccommodation1 person (pilot)The DeepWorker's small size and light weight can be attributed to technological developments that have been realized over the last several decades. Everything from onboard computers to air supply tanks has been miniaturized.DeepWorker ConstructionThe DeepWorker's pressure hull consists of a 38-inch steel sphere attached to a cylinder that is 24 inches wide and 36 inches long. A 30-in-wide acrylic dome serves as the entry hatch and provides the pilot with a fantastic 250-270-degree field of vision. Beneath the hull are two 18-in-wide titanium battery pods. Maneuvering control is provided by two vertical and two horizontal 1-horsepower thrusters. Trim is controlled by a hard ballast system and fixed weights. A soft ballast system is provided for buoyancy on the surface and as a means of emergency ascent.The DeepWorker's life-support system includes two externally mounted oxygen cylinders, two redundant mechanical oxygen controllers with electronic monitoring inside the cockpit, and two carbon dioxide scrubbers. Communications systems include VHF multi-channel radio for surface communications, and an acoustic through-water telephone for subsurface communications. Additional equipment includes sonar, cameras, a manipulator arm, tracking beacon, a precision laser measuring system, and scientific sampling equipment.The DeepWorker's dome allows explorers to enter and provides a 250-270 degree field of vision.

The pilot uses a touch screen to power up the sub, to control lights, and to monitor depth. These are just a few of the functions controlled by the touch screen.

All critical computer functions have analog or mechanical backups.The DeepWorker is steered by foot pedals, a new innovation unique to this submersible. The essentially hands-free operation enables the pilot to simultaneously maneuver the sub, operate the manipulator arms and/or cameras, and take notes.Because the controls are much like those that operate a car, pilots find their intuition taking over. Pressing with the ball of the right foot makes the sub go forward, and pressing with the right heel makes it go backward. The left foot controls up-and-down movement, and pressing outward to the sides with either foot steers the DeepWorker left or right.

The addition of two angled thrusters, one on each side of the submersible, gives DeepWorker the capability of moving from side to side, in addition to up and down. The thrusters system allows the submersible to travel at the speed of 3 to 4 knots in any direction.While inside DeepWorker, the pilot interacts with the underwater environment by using the manipulator arms, which have a wide range of motion because they are jointed like a human arm. They can cut cable, as well as lift, grab and hold objects. Instruments can even be mounted on the arms.Other instruments are strapped to the outside of DeepWorker. Lights and sophisticated still and video camera systems record the underwater areas that DeepWorkerencounters. Another instrument, called a polar scan sonar, shows the outline of underwater objects beyond the range of visibility.The construction of DeepWorker has many advantages over its predecessors. In the past, submersibles were large and heavy, requiring large dedicated vessels for transport, launch and recovery. DeepWorker is transportable by trailer over land, and when it reaches its destination port, it can be launched from a much wider variety of ship platforms.Another advantage of DeepWorker is that it is a directly operated vehicle. Many occupied submersibles, and almost all remotely operated vehicles (ROVs), are connected to ships by a tether containing power and communications cables. The tether supplies the necessary power supply to run the submersible, but it also creates a problem. Tethers are heavy and create drag on the submersible as it moves through the water, decreasing its maneuverability. Launch and recovery is more complicated, and tethers can also increase the risk of entanglement. In contrast, DeepWorker is a completely self-contained, lightweight submersible that can carry an explorer to unknown reaches at a moment's notice.
