The symptoms of water pressure at 33-100 feet include mild impairment of performance of unpracticed tasks, mildly impaired reasoning and mild euphoria.

Symptoms at 100-165 feet include delayed response to visual and auditory stimuli, diminished reasoning and memory capacity (to a greater extent than motor functions), calculation errors and wrong choices, obsessive fixation on a single and sometimes arbitrary idea, over-confidence and an increased sense of well-being, laughter and a tendency to talk much more than usual.

Symptoms at 165-230 feet include sleepiness, impaired judgment, confusion, hallucinations, severe delay in response to signals/instructions, dizziness, uncontrollable laughter/hysteria, and occasionally terror.

Symptoms at 230-300 feet include poor concentration and mental confusion, stupefaction with further decreased dexterity and judgment, greater loss of memory and increased excitability.

>>How would they be cheaper?

Materially. No surface structure.

>>After all the ocean happens to be corrosive to many engineering materials and protecting them can be expensive. Also, stress corrosion cracking.

Less so with modern materials.

>>Last time I checked hydrothermal power meant Ocean ThermoElectricConversion(OTEC). OTEC relies on the termperature differential between warm water at the surface and deeper cool water. So there's a very good reason to set up a surface rig.

I meant the seafloor equivalent of geothermal, tapping undersea volcanos for energy.

>>except that currently no aquaculture approaches use submarines.

We're discussing future possibilities. Aquaculture on a large scale carried out by those living undersea would require small submarines.

>>Also if subs with fuel cells could be used why not surface vessels?

Because those living in an undersea colony would be acclimated to a different pressure. Why have the crew undergo many hours of decompression to do clumsily from the surface what they can do immediately and dextrously from the bottom?
