I'm starting to question what I said about the gas...

If you have gas in a sealed chamber and you want to move that gas from the top of the sealed chamber to the bottom... would it matter if the chamber was submerged in water or not? Does a gas become more buoyant the deeper it is submerged in water? I'm not sure...

The buoyant forces acting on a submerged body do not change that much with depth due to the very low compressibility of liquids. They depend only on the weight of the volume of water displaced as the object is submerged.

However, the pressure acting on a submerged body definitely increases dramatically with depth. For every approximtely 32 feet deeper an object is submerged, the average pressure acting on its external surfaces will increase by about 14.7 lbs per square inch. That works out to over 2100 lbs per square foot!

At a depth of 320 feet, the external pressure of the water will be about 147 lbs per square inch or 21,000 lbs per square foot. To prevent his internal body cavities from being crushed by the external water pressure at a depth of 320 feet, a skin diver must breath air from a tank with the same pressure as the water he is immersed in.
