What is nautile submersible?

The Nautile submersible is a deep-sea exploration vehicle designed to explore depths up to 6,000 meters (19,700 feet). It was developed in the 1980s by the French deep-sea research institute Ifremer and is still in use today.

The Nautile submersible is operated by a team of two pilots who sit in a small spherical chamber made of titanium. The chamber is filled with a mixture of helium and oxygen to prevent nitrogen narcosis and oxygen toxicity at depth. The submersible is propelled by four electric thrusters and can reach a top speed of 2.5 knots.

The Nautile is equipped with a suite of scientific instruments, including cameras, lights, sonar, and a manipulator arm to collect samples and perform experiments. It has been used to explore areas such as hydrothermal vents, deep-sea canyons, and shipwrecks.

The Nautile has been involved in several high-profile expeditions, including the discovery of the wreckage of the Titanic in 1985, and the exploration of the deep-sea ecosystems around the Pacific Rim. It has also been used to study the effects of deep-sea mining and to collect data on the impact of climate change on deep-sea ecosystems.
