Short summary
This paper presents the chemical and iron isotopic composition of aerosols (> 1 µm) over the equatorial and tropical Pacific Ocean in previously undocumented areas. Analysis of our data suggests that a significant proportion of aerosol iron (∼ 13 %) is not only dissolved but also removed during atmospheric transport. Such removal had not previously been evidenced to our knowledge. This highlights the unique and strong constraints brought by iron isotopes on atmospheric process studies.
