Chromium

Using chromium isotopes to reconstruct the oxygenation history of the oceans is challenged by modern data

Analyses of seawater chromium (Cr) concentrations and isotopes in diverse marine environments (Arctic, Pacific, and Atlantic Oceans) reveal a strong correlation between Cr isotope composition (δ53Cr) and Cr concentration. High δ53Cr values and low Cr concentration reflect losses of isotopically light Cr in neritic environments. Contrastingly, open ocean waters with low δ53Cr values and high […]
