Biogeochemical cycling of chromium and chromium isotopes in the sub-tropical North Atlantic Ocean
Chromium (Cr) is a redox-sensitive element and because Cr isotopes are fractionated by redox and/or biological processes, the Cr isotopic composition of ancient marine sediments may be used to infer changes in past seawater oxygenation or biological productivity. While there appears to be a ‘global...
