Re: What structure would be best for living community on the ocean floor?

Due to the pressures involved in living under the ocean surface, the best
structures would mimic those used in space... such as a sphere or cylinder.
The best references I could name would be those involving submersible
design.  Also, the US Navy had a project in the 60's or 70's for an
undersea research station... You might look that up, as it would probably
have some unclassified design parameters you could use.
