I remember someone in Florida a few years back was selling bottled hurricane air--air bottled during a hurricane.
That makes sense. Hurricane = high pressure area. More pressure = more air in the tank = longer dives.
Normally atmospheric pressure isn't an issue, because most bottling occurs at sea level. Inland dive centres may be at a higher altitude (less air pressure) - and consequently give weaker fills. I'd always get my fills from a sea-level cannery.
I heard that they get helium from mines... higher pressure then, as below sea level.... better for deep diving. That's a primary benefit.
They should mine for regular air too... for those of us who like deep air diving. It'd also make Nitrox production cheaper. Less oxygen at altitude. More oxygen at depth. Would save having to blend, if they took nitrox directly from a deep well. I'm sure someone could calculate what depth needed to be bored to obtain 32%.
