At extreme depths, the cable becomes unmanageable. Deeper dives must be performed by self-propelled vehicles such as a Bathyscaphe.
The term bathysphere is composed from the Greek words βάθος (bathys), "depth" and σφαίρα (sphaira), "sphere".
The first bathysphere was built by Otis Barton and William Beebe in 1930.
'Bathysphere' is also a song by indie rock band Smog.
