The Bathysphere (Greek: βαθύς, bathus, "deep" and σφαῖρα, sphaira, "sphere") was a unique spherical deep-sea submersible which was unpowered and lowered into the ocean on a cable, and was used to conduct a series of dives off the coast of Bermuda from 1930 to 1934.

The bathysphere was a hollow, steel ball less than five feet in diameter with three small windows and a steel cable to tether it to a ship.
In the 1930s, the bathysphere propelled scientists deeper into the sea than they had ever been before.
