The last point means that for every cubic meter of sea water you get a little more than three cubic meters of atmospheric oxygen.

Without really trying to be accurate, the numbers being used (0.2778 and 8.58) are in a 1:30 ratio not a 1:3 ratio.

Well, I was taking Junior's word for it (which he later corrected but I had not seen). Your figures sound more reasonable than his second statement of a 3000 to 1 ratio.

I know, and I corrected the mistake.

Actually, its 0.2778 and 858, or a 1:3000 ratio. There are 0.2778 kgs of oxygen per cubic meter of air, and their are 858 kilograms of oxygen per cubic meter of water.
