"WebThe composition of seawater changed significantly during the course of the Phanerozoic in concert with long-term changes in sea level, which were largely the result of changes in the volume of mid-ocean ridges. These reflect changes in the rate of seafloor spreading and determine the rate of seawater cycling through mid-ocean ridges. [Spencer and Hardie … " - Composition of seawater pdf
