But their history shows that this is far from the case.

Key Points: 
  • But their history shows that this is far from the case.
  • Bathyspheres were unpowered submersibles lowered into the sea on a cable and used for pioneering dives in the early 1930s.
  • Since then, submersibles have taken many more people into the deep ocean than the number of humans who have been into space.
  • Fumes from an electrical fire overcame the occupants of a Japanese tethered diving bell at around 10 metres deep in 1974.

Pushing the limits

    • The first to do so was a bathyscaphe – a submersible suspended below a float, rather than from a cable like the bathysphere.
    • It was called FNRS-3 and it set an overall depth record for the time, reaching 4,050 metres in 1954.
    • Over a 14-year period starting in 1991, the two Russian Mir submersibles visited the Titanic wreck than any other vehicle.

Today’s submersible fleet

    • But there are currently seven submersibles in service that can reach the depth of the Titanic and beyond.
    • There is one very deep-diving submersible in private ownership: the Limiting Factor was built by Triton Submarines for Texan billionaire Victor Vescovo to pilot to the deepest point in all five oceans in 2019.
    • The Aluminaut submersible of the 1960s, which was capable of diving to 4,500 metres, had an aluminium hull with a tubular shape that could carry seven people.
    • In 2013, I dived aboard Japan’s Shinkai 6500 submersible to study undersea hot springs at 5,000 metres deep on the ocean floor.

NASSAU, Bahamas, Oct. 25, 2022 /PRNewswire-PRWeb/ -- During the 2022 Titanic Expedition an extremely productive and dense ecosystem was discovered 2900 meters deep near the wreck of the Titanic. The provisionally dubbed Nargeolet-Fanning Ridge was originally recorded as a blip on sonar 26 years ago by PH Nargeolet, a veteran Nautile submersible pilot and Titanic diver. After more than two decades of wondering if the blip was a shipwreck or geologic feature, PH got his chance to dive on the target and explore the ridge that now provisionally carries his name. The mystery was finally solved with the financial support of OceanGate Expeditions Mission Specialist Oisín Fanning and the analysis provided by OceanGate Foundation's scientific team. Video footage released by OceanGate Expeditions shows the awe-inspiring environment that was discovered.
