Deep Water

Why is the deep ocean zinc isotopic signature so heavy?

The oceanic balance of the micronutrient zinc (Zn) is getting more puzzling –although better documented- while the Zn isotope data set increases. Presenting the first high resolution section of seawater dissolved Zn concentration and Zn isotope ratios (δ66Zn) from the North Atlantic, Conway and John (2014, see reference below) confirm that the deep ocean is […]
