Isotopic chromium variations do not always reflect the occurrence of low oxygenated waters
Dissolved chromium (Cr) in the ocean is present under two oxidation states: The oxidized and soluble Cr (VI) and the reduced more reactive Cr (III). Reduction of Cr (VI) to […]

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 […]
