Degassing of ocean
Dissolved gasses escape when bubbles move to the surface
Bursting bubbles send small droplets of water into air
Largest fall back to sea, but smallest remain in the air, carrying dissolved constituents
Degassing may remove as much as 1-2 x 109 tons of all of the primary dissolved constituents, Na+1, Cl-1, Mg+2, SO4-2, HCO3-1, etc.
