A five-person submersible designed for deep-sea tourism and research. It can dive up to 1,000 feet, allowing scientists and visitors to explore marine life beyond typical scuba diving depths. Operated from Curacao, it provides a rare opportunity for civilians to experience deep-sea exploration.
2. Seamagine Hydrospace Corps.’ Submarine
Seamagine specializes in personal submersibles for private and research use. Their submarines, such as the Aurora series, are designed for two to six passengers and can dive between 330 and 3,300 feet. They are used for underwater filming, marine research, and luxury exploration.
3. Woods Hole Oceanographic Institute’s ‘Slocum Glider’
An autonomous underwater vehicle (AUV) designed for long-term ocean monitoring. It moves by adjusting buoyancy, allowing it to glide through water with minimal energy use. Used for collecting oceanographic data, it can operate for months without human intervention.
4. Notilo Plus’s ‘Seasam’
A compact, AI-powered underwater drone used for inspections and mapping. It is capable of autonomous navigation, making it useful for industrial, scientific, and security applications. Controlled via tablet, it provides real-time data and video feed.
5. Woods Hole Oceanographic Institute’s ‘ABE’
ABE (Autonomous Benthic Explorer) was an unmanned deep-sea research vehicle used for mapping and surveying the ocean floor. It was capable of diving over 15,000 feet but was lost during an expedition in 2010. It paved the way for more advanced underwater exploration robots.
6. Triton 36,000 Full Depth Ocean submarine
One of the deepest-diving submersibles ever built, designed to reach the deepest parts of the ocean. It successfully carried a human to the bottom of the Mariana Trench in 2019. Built with extreme pressure resistance, it allows for deep-sea research and exploration.
7. U-Boat Worx Nemo
A luxury personal submarine designed for private owners and yachts. Compact and lightweight, it can dive up to 330 feet and offers a panoramic acrylic dome for a full underwater view. Marketed as an easy-to-operate sub for ocean enthusiasts it offers immersive marine exploration experiences.
8. Schmidt Ocean Institute’s ‘Sentry’
This is an autonomous underwater vehicle (AUV) designed for deep-sea exploration. It can map the ocean floor and collect high-resolution images at depths up to 19,000 feet. Used in scientific research, it helps study hydrothermal vents and marine geology.
9. Schmidt Ocean Institute’s ‘HOV Alvin’
A legendary deep-sea submersible that has been in operation since 1964. It has made thousands of dives, including explorations of the Titanic and hydrothermal vents. Carries up to three people and reaches depths of 14,700 feet.
10. Schmidt Ocean Institute’s Deepsea Challenger
Designed for single-person deep-sea exploration, this submersible was built for filmmaker James Cameron’s historic 2012 dive to the Mariana Trench. Engineered for extreme depths, it provided valuable scientific data and footage from the ocean’s deepest known point.
11. Deepsea Exploration’s Idabel submersible
This privately owned, deep-diving sub offers tourist expeditions in Roatán, Honduras. Capable of reaching depths over 3,000 feet, it allows passengers to explore marine life rarely seen in shallow waters. Used for both tourism and scientific observation.
12. Blueye Robotic’s ‘X3’
A professional-grade underwater drone used for inspections, research, and exploration. It can operate at depths of up to 1,000 feet and provides high-definition video footage. Controlled remotely, it is often used for ship hull inspections and marine studies.
13. Boxfish Robotics’ ROV
A remotely operated vehicle (ROV) designed for underwater filmmaking, research, and industrial inspections. It delivers ultra-clear video and operates in challenging conditions. Used for marine science, oil and gas industry surveys, and documentary production.
14. Woods Hole Oceanographic Institute’s ‘Orpheus’
This is an autonomous underwater vehicle for exploring hadal zones (6,000-11,000m deep). It uses advanced vision and AI to navigate extreme depths independently. The machine is part of NASA's analog testing for potential ocean worlds like Europa.
