Re: Cybersuit -- Submersible or Not?
I think it's quite possible that the cybersuit does something like flood the user's lungs with breathable fluids and other such adjustments. It is a TL 11 item after all, so it can probably take those techniques far enough for them to be good at 30 atm without needing to be rigid.

Re: Cybersuit -- Submersible or Not?
Yes, I'm not saying that the pressure has higher penetration, insofar as that's even halfway meaningful. But when you put things in terms of force, well, there's a whole lot of it involved (unless you do the vector sum, in which case there's almost none).
However, the point about huge force totals does have importance. Supporting that pressure over, for instance, the pressure hull of a submarine takes impressively sturdy construction. And in the case of a thin suit, you not only have to hold out the pressure in a much less structurally sound shape, you have to do it with almost no deformation, because there isn't room to deform while keeping the pressure off the occupant.

Oxygen becomes toxic long term above around 0.4 atm partial pressure which would be air at just twice sea level. Keeping that at safe levels requires other filler gases which themselves become toxic at high pressures. Nitrogen narcosis, high pressure nervous syndrome for helium, etc. Pressure support is most useful for going up and down quickly, something that kills people that when done slowly is almost trivial.

Sperm whales. Diving up to 3,000 yards underwater, which is almost 300 atmospheres of pressure. That's Pressure Tolerance 3 right there. But I think at most they'd qualify for DR (Tough Skin), not for something rigid. |

A creature having large pressure tolerance range usually (probably always for non-fictional organisms) means having physiological adaptations to cope with various pressures and changing pressure, not actually resisting the pressure in any way. A suit of armor or vehicle providing pressure tolerance means that it actually sustains a pressure differential, allowing the occupant to remain at a tolerable pressure while the outside environment does not.

Re: Cybersuit -- Submersible or Not?
Hmm. Checking the information on hard-hat diving suits (of leather or airtight cloth, despite a hard helmet), reportedly they can be used down to a depth of 180 metres, which is 18.8 atmospheres, which in GURPSese would indicate slightly above Pressure Support 1 (which grants ability to function at 10 atmospheres).

Re: Cybersuit -- Submersible or Not?
The purpose of drysuits is thermal insulation, not pressure support.
