The Remote Operated Vehicle (ROV) SuBastian is owned and operated by the Schmidt Ocean Institute and is used for scientific exploration of the deep sea. ROV SuBastian is operated from the Schmidt Ocean Institute's research vessel RV Falkor and can reach depths up to 4,500m (2.8 miles). [1] The tethered robot has an array of scientific capability which includes:
ROV SuBastian is an adaptable system and additional sensors and scientific instruments can be mounted onto the ROV based on a science party’s specific research goals. [1]
ROV SuBastian was named after the character Bastian from the German fantasy novel The Neverending Story (Bastian) combined with “sub,” as the vehicle is used subsurface. ROV SuBastian operates solely from R/V Falkor. [2]
ROV SuBastian was specifically designed and constructed for scientific research in 2015 by a California-based team of engineers. The design and construction process took approximately 18 months. SuBastian was tank tested at the Monterey Bay Aquarium Research Institute prior to its first deep sea launch. [3] The inaugural dive occurred in 2016 in the deep sea off Guam. [4] As of 2020, ROV SuBastian has completed over 400 dives around the globe, enabling researcher’s access to remote regions and depths. Researchers utilizing ROV SuBastian have discovered new species, seafloor features, and advanced scientific exploration of the global ocean. [5] [6] [7] [8]
ROV SuBastian weighs 3,200kg and is 2.7m x 1.8m x 1.8m, roughly the same size as a subcompact car. The vehicle is fitted with syntactic foam, allowing it to be neutrally buoyant while diving. SuBastian moves using five thrusters; one thruster moves it sideways, two move it forward and back, and another two are used for vertical movement. It is tethered to Falkor with a highly flexible and robust umbilical cable, which provides electrical and optical signals between the ship and ROV. The umbilical uses a cantilever system to avoid entanglement with propellers. ROV SuBastian transits at a speed of 0.5 – 3 knots, depending on depth and currents. Once deployed, ROV SuBastian is controlled by at least two pilots aboard the ship. The dive length depends on objective, depth, and weather. The average dive time is around 8 hours, but there are no technical limits on how long an ROV can stay down. [2] [9]
The Challenger Deep is the deepest known point of the seabed of Earth, with a depth of 10,902–10,929 m (35,768–35,856 ft) by direct measurement from deep-diving submersibles, remotely operated underwater vehicles and benthic landers, and (sometimes) slightly more by sonar bathymetry.
Alvin (DSV-2) is a crewed deep-ocean research submersible owned by the United States Navy and operated by the Woods Hole Oceanographic Institution (WHOI) in Woods Hole, Massachusetts. The vehicle was built by General Mills' Electronics Group in Minneapolis, Minnesota. Named to honor the prime mover and creative inspiration for the vehicle, Allyn Vine, Alvin was commissioned on 5 June 1964. The submersible is launched from the deep submergence support vessel RV Atlantis (AGOR-25), which is also owned by the U.S. Navy and operated by WHOI. The submersible has made more than 5,000 dives, carrying two scientists and a pilot, to observe the lifeforms that must cope with super-pressures and move about in total darkness, as well as exploring the wreck of Titanic. Research conducted by Alvin has been featured in nearly 2,000 scientific papers.
A remotely operated underwater vehicle is a tethered underwater mobile device, also commonly called an underwater robot.
A submersible is a 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 self-sufficient craft, capable of independent cruising with its own power supply and air renewal system, whereas a submersible is usually supported by a nearby surface vessel, platform, shore team or sometimes a larger submarine. In common usage by the general public, however, the word "submarine" may be used to describe a craft that is by the technical definition actually a submersible, and by the standard meaning of the word, all submarines are submersibles.
The Monterey Bay Aquarium Research Institute (MBARI) is a private, non-profit oceanographic research center in Moss Landing, California. MBARI was founded in 1987 by David Packard, and is primarily funded by the David and Lucile Packard Foundation. Christopher Scholin serves as the institute's president and chief executive officer, managing a work force of approximately 220 scientists, engineers, and operations and administrative staff.
Unmanned underwater vehicles (UUV), sometimes known as underwater drones, are submersible vehicles that can operate underwater without a human occupant. These vehicles may be divided into two categories: remotely operated underwater vehicles (ROUVs) and autonomous underwater vehicles (AUVs). ROUVs are remotely controlled by a human operator. AUVs are automated and operate independently of direct human input.
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. The ROV allows scientists and explorers to have access to the seafloor without leaving the deck of a ship.
Subsea technology involves fully submerged ocean equipment, operations, or applications, especially when some distance offshore, in deep ocean waters, or on the seabed. The term subsea is frequently used in connection with oceanography, marine or ocean engineering, ocean exploration, remotely operated vehicle (ROVs) autonomous underwater vehicles (AUVs), submarine communications or power cables, seafloor mineral mining, oil and gas, and offshore wind power.
Deep-sea exploration is the investigation of physical, chemical, and biological conditions on the ocean waters and sea bed beyond the continental shelf, for scientific or commercial purposes. Deep-sea exploration is an aspect of underwater exploration and is considered a relatively recent human activity compared to the other areas of geophysical research, as the deeper depths of the sea have been investigated only during comparatively recent years. The ocean depths still remain a largely unexplored part of the Earth, and form a relatively undiscovered domain.
Intervention AUV or I-AUV is a type of autonomous underwater vehicle. Its characteristic feature is that it is capable of autonomous interventions on the subsea installations, a task usually carried out by remotely operated underwater vehicles (ROVs) or human divers.
Nereus was a hybrid uncrewed autonomous underwater vehicle built by the Woods Hole Oceanographic Institution (WHOI). Constructed as a research vehicle to operate at depths of up to 11,000 metres (36,000 ft), it was designed to explore Challenger Deep, the deepest surveyed point in the global ocean. Nereus, named for Greek sea titan Nereus through a nationwide contest of high school and college students, began its deep sea voyage to Challenger Deep in May 2009 and reached the bottom on May 31, 2009.
NOAAS Okeanos Explorer is a converted United States Navy ship, now an exploratory vessel for the National Oceanic and Atmospheric Administration (NOAA), officially launched in 2010. Starting in 2010, NOAA entered into a five-year partnership with the San Francisco Exploratorium. The focus is on gathering scientific information about oceans for the public as well as for scientific uses. As much as 95% of the ocean remains unexplored, NOAA officials said. The ship is equipped with cameras and will provide real-time viewing of the ocean floor for scientists and for the public.
Global Explorer ROV is a unique deep water remotely operated vehicle that has made numerous dives below 9,000 feet (2,700 m) on science and survey expeditions for National Geographic, the National Oceanographic and Atmospheric Administration (NOAA) and other research organizations. It was designed and built by Chris Nicholson of Deep Sea Systems International, Inc. of Falmouth, Massachusetts.
ABISMO is a remotely operated underwater vehicle (ROV) built by the Japan Agency for Marine-Earth Science and Technology (JAMSTEC) for exploration of the deep sea. It is the only remaining ROV rated to 11,000-meters, ABISMO is intended to be the permanent replacement for Kaikō, a ROV that was lost at sea in 2003.
Liquid Robotics is an American marine robotics corporation that designs, manufactures and sells the Wave Glider, a wave and solar powered unmanned surface vehicle (USV). The Wave Glider harvests energy from ocean waves for propulsion. With this energy source, Wave Gliders can spend many months at a time at sea, collecting and transmitting ocean data.
Deepsea Challenger is a 7.3-metre (24 ft) deep-diving submersible designed to reach the bottom of Challenger Deep, the deepest-known point on Earth. On 26 March 2012, Canadian film director James Cameron piloted the craft to accomplish this goal in the second crewed dive reaching the Challenger Deep. Built in Sydney, Australia, by the research and design company Acheron Project Pty Ltd, Deepsea Challenger includes scientific sampling equipment and high-definition 3-D cameras; it reached the ocean's deepest point after two hours and 36 minutes of descent from the surface.
RV Falkor is an oceanographic research vessel operated by the Schmidt Ocean Institute. Ship time aboard the vessel is made freely available to researchers once they have undergone an application, peer review process, and their proposal has been accepted. One condition for using the Falkor is that research findings and data from all expeditions are made publicly available. Researchers aboard Falkor receive expert shipboard support, use of scientific equipment, as well as robotic and computational resources. RV Falkor is adaptable and can facilitate new technologies and external resources as required for each science expedition. Falkor’s current status and a virtual ship tour are publicly available on the Schmidt Ocean Institute website. The Schmidt Ocean Institute announced the change of ownership of the vessel on 14. March 2022. It was renamed to Gaia Blu and is used by the italian National Research Council. It concluded its first science expedition at the 20. October 2022.

The Institute's goal is to advance innovative oceanographic research and discovery through technological advancement, collaborative research, outreach and education, and open sharing of information. SOI supports oceanographic research by providing collaborators with free ship time aboard their research vessel Falkor (too) and expert technical shipboard support. Collaborating researchers and institutions utilizing Falkor commit to openly share and communicate the outcomes of their research, including raw observations and data. Research proposals are reviewed through a peer-reviewed process and assessed based on their potential for technological innovation, oceanographic research, and overall impact. Since its inception in 2009, SOI has supported over 60 expeditions all around the globe.
Diving support equipment is the equipment used to facilitate a diving operation. It is either not taken into the water during the dive, such as the gas panel and compressor, or is not integral to the actual diving, being there to make the dive easier or safer, such as a surface decompression chamber. Some equipment, like a diving stage, is not easily categorised as diving or support equipment, and may be considered as either.
Underwater exploration is the exploration of any underwater environment, either by direct observation by the explorer, or by remote observation and measurement under the direction of the investigators. Systematic, targeted exploration is the most effective method to increase understanding of the ocean and other underwater regions, so they can be effectively managed, conserved, regulated, and their resources discovered, accessed, and used. Less than 10% of the ocean has been mapped in any detail, less has bee visually observed, and the total diversity of life and distribution of populations is similarly obscure.
