bathyscaphe
Deep-sea diving vessel
A bathyscaphe is a self-propelled deep-sea submersible designed to reach extreme ocean depths.
Unlike submarines, it uses a float chamber filled with gasoline for buoyancy and drops iron ballast to descend or ascend.
The bathyscaphe *Trieste* carried two men to the bottom of the Mariana Trench in 1960—the deepest point in any ocean.
