As an essential micronutrient, iron plays a key role in oceanic biogeochemistry. It is therefore linked to the global carbon cycle and climate. Here, we report a dissolved iron (DFe) isotope section in the South Atlantic and Southern Ocean.

- - This study showcases the successful measurement of iron isotopes in seawater, even in very low concentrations (0.05-1 nmol L(-1)), which is important for understanding nutrient-depleted ocean areas.
- - The improved measurement technique involves preconcentrating iron using specific resins and analyzing it with advanced mass spectrometry, achieving high precision for isotopic ratio determination.
- - The results indicate that the method can detect significant variations in iron isotopic composition across the ocean, bringing new insights into the oceanic iron cycle.
