Why do we find a walk in the woods invigorating?
Because we are being bathed in an oxygen rich atmosphere created by the trees...maybe?
Sounds like a testable idea. (Barbarian checks)
Don't see any immediate data. Given that the Arctic and Antarctic seas produce more oxygen than the Earth's forests, (cold seawater is the best environment for phytoplankton) I would suspect that the highest oxygen levels would be at sea level near the poles.
I think you might be right. Could also be why boating in the ocean is invigorating.
