In science and geography lessons submersibles explore the ocean floor, shipwrecks such as the Titanic and deep trenches like the Mariana Trench. They are different from submarines, which are bigger and travel on their own for long trips. Phrases: "deep-sea submersible", "manned submersible", "submersible pump".
