Main Page | See live article | Alphabetical index A bathysphere is a spherical deep-sea diving submersible which is lowered into bodies of water with a cable. Bathyspheres have a variety of uses, usually including the study of underwater life. At extreme depths, the cable becomes unmanageable. Deeper dives must be performed by self-propelled vehicles such as the bathyscape. See also Timeline of underwater technology. This is a stub. This article is from Wikipedia.
