Three main types of submersibles have been used on recent NOAA Ocean Exploration-supported missions: human-occupied vehicles (HOVs), remotely operated vehicles (ROVs), and autonomous underwater vehicles (AUVs). Human-occupied vehicles (HOVs) transport a small team of scientists and pilots directly to the seafloor for a limited amount of time.

What is a submersible?
A submersible is a small watercraft designed to operate underwater.
What is the difference between a submersible and a submarine?
The term submersible is often used to differentiate from other underwater vessels known as submarines, in that a submarine is a fully autonomous craft, capable of renewing its own power and breathing air, whereas a submersible is usually supported by a surface vessel, platform, shore team or sometimes a larger submarine.
Who built the first underwater vessel?
The first underwater vessel was designed and built by Dut ch inventor Cornelis Drebbel in 1620, with two more built in the following four years. Contemporary accounts state that the final model was demonstrated to King James I in person and that the monarch himself was taken aboard for a test dive, although more recently, these accounts have been called into question as an exaggeration.
How deep is the Mariana trench?
Cameron's submersible was named Deepsea Challenger and reached a depth of 10,908 metres (35,787 ft).
How deep can a manned submarine dive?
Operated by a pilot, with some models able to hold other passengers and/or co-pilots, manned submarines are now able to dive to maximum depths of 6,000m. Alvin was one of the first deep sea submersibles that could carry passengers.
How deep can Alvin dive?
With upgrades to its hull and life support system, Alvin can now dive to a depth of 14,700 feet, and can remain submerged for up to 72 hours. This long-lasting submersible boasts over 4,000 dive expeditions and has carried more than 13,000 passengers to the ocean deep.
What is a ROV?
Remotely operated submersibles, or vehicles (ROV), are submersibles tethered to and operated from shore. They are unoccupied and hold various instruments for data collection. The advantages of ROVs include greater safety, and a larger array of instruments, but these ROV’s tend to be bulkier.
What are the advantages of a ROV?
They are unoccupied and hold various instruments for data collection. The advantages of ROVs include greater safety, and a larger array of instruments, but these ROV’s tend to be bulkier. Also, because many ROV’s carry a large amount of devices on-board, more than 1 remote operator may be required.
What is an AUV used for?
AUV’s can be used to survey and map the ocean floor, and return measurements of the ocean water conditions such as temperature and salinity. AUV’s in use today include the Remote Environmental Monitoring UnitS submersibles (REMUS), the Sentry, Spray Gliders, and the Slocum Glider.
What is a spray glider?
Spray gliders are utilized for measuring water conditions like temperature, salinity, pressure, and turbidity. Moreover, Spray gliders can measure the speed of ocean currents as well as provide the chemical decomposition in the water.
What is a sentry?
The Sentry is a versatile AUV that can produce depth analysis and magnetic maps of the ocean floor, as well as taking photographs of deep-sea geological features like deep-sea vents. A durable submersible, the Sentry can operate in extreme conditions, like volcano calderas.
What is Woods Hole Oceanographic Institution?
Drawing on 90 years of leadership in ocean discovery and exploration, Woods Hole Oceanographic Institution (WHOI) scientists are engaged in an array of research projects using autonomous systems to advance their understanding of marine environments.
Is Vermont colder than the Arctic?
New England winters can often feel as cold as the Arctic. But for researchers from WHOI’s Applied Ocean Physics & Engineering department, Vermont’s polar-like cold proved to be the perfect testing site for Remus 600. The state’s deepest lake – Lake Willoughby – offered fewer risks than the Arctic Ocean, while providing important data about ice measurement and water temperature, helping to streamline the real mission this fall.
Overview
A submersible is a small watercraft designed to operate underwater. The term submersible is often used to differentiate from other underwater vessels known as submarines, in that a submarine is a fully autonomous craft, capable of renewing its own power and breathing air, whereas a submersible is usually supported by a surface vessel, platform, shore team or sometimes a larger submarine. In common usage by the general public, however, the word submarine may be used t…
History
The first underwater vessel was designed and built by Dutch inventor Cornelis Drebbel in 1620, with two more built in the following four years. Contemporary accounts state that the final model was demonstrated to King James I in person and that the monarch himself was taken aboard for a test dive, although more recently, these accounts have been called into question as an exaggeration.
Operation
Apart from size, the main technical difference between a "submersible" and a "submarine" is that submersibles are not fully autonomous and may rely on a support facility or vessel for replenishment of power and breathing gases. Submersibles typically have shorter range, and operate primarily underwater, as most have little function at the surface. Some submersibles operate on a "tether" or "umbilical", remaining connected to a tender(a submarine, surface vessel …
Technologies
There are five basic technologies used in the design of submersibles. Single atmosphere submersibles (one atmosphere subs) have a pressurized hull and the occupants are at standard atmospheric pressure. This requires the hull to be capable of withstanding the high pressure from the water outside that is many times greater than the internal pressure.
Another technology called ambient pressure maintains the same pressure both inside and outsi…
Deep-diving crewed submersibles
Some submersibles have been able to dive to great depths. The Bathyscaphe Trieste was the first to reach the deepest part of the ocean, nearly 11 km (7 mi) below the surface, at the bottom of the Mariana Trench in 1960.
China, with its Jiaolongproject in 2002, was the fifth country to send a man 3,500 meters below sea level, following the US, France, Russia and Japan. On June 2…
Commercial submersibles
More recently, private firms such as Florida based Triton Submarines, LLC. SEAmagine Hydrospace, Sub Aviator Systems (or 'SAS'), and Netherlands-based U-Boat Worx have developed small submersibles for tourism, exploration and adventure travel. A Canadian company in British Columbia called Sportsub has been building personal recreational submersibles since 1986 with open-floor designs (partially flooded cockpits).
MROVs
Small uncrewed submersibles called "marine remotely operated vehicles" or MROVs are widely used today to work in water too deep or too dangerous for divers.
Remotely operated vehicles (ROVs) repair offshore oil platforms and attach cables to sunken ships to hoist them. Such remotely operated vehicles are attached by an umbilical cable(a thick cable providing power and communications) to a control center on a ship. Operators on the ship see vi…
