Short summary
This manuscript presents the iron (Fe) concentrations and isotopic compositions of seawater samples for the dissolved and particulate phases in the western and central equatorial Pacific Ocean. The results illustrate the potential of Fe isotopes as powerful tracers for studying the sources and processes influencing Fe in the open ocean. Our analysis reveals an exchange between dissolved and particulate Fe phases, as well as the long-distance preservation of Fe isotopic signatures.
