Abstract

The size partitioning of dissolved Fe (dFe<0.2 µm) into soluble (sFe<0.02 µm) and colloidal (0.02 µm56Fe of +1.3‰ to +1.5‰) relative to dFe (δ⁵⁶Fe~+0.5‰) in the surface ocean where sFe and cFe cycle independently, and identical sFe and dFe isotope ratios below 250 m where sFe and cFe are constantly partitioned and exchanged.
