Web15 mrt. 2002 · Calcium is one of the major ions in seawater. It is present in seawater at about 410 ppm the world over, so it comprises just under 1.2% by weight of the solids. Variations from this concentration are most often caused by changes in salinity, where the calcium goes up and down just as the salinity does. Web2 nov. 2001 · We interpret these data to indicate that the major-ion chemistry of seawater has systematically changed over the last 540 My. However, others have suggested that any such signal may be obscured by basinal- or global-scale dolomitization of flooded carbonate platforms, which altered the Mg 2+ /Ca 2+ ratio of the evaporating brines, yielding …
