Iron is mostly bound to poorly characterised organic ligands, thus, organic ligands are paramount in defining Fe biogeochemical cycling and its control on oceanic primary productivity. Since 1994, Fe chemical speciation has been determined by Competitive Ligand Exchange– Adsorptive Cathodic Strippin...
