Short summary
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.

Short summary
Short summary
Oxygen availability in marine water and freshwater is very variable at daily and seasonal scales. The dynamic nature of oxygen fluctuations has important consequences for animal and microbe physiology and ecology, yet it is not fully understood. In this paper, we showed the heterogeneous nature of the aquatic oxygen landscape, which we defined here as the
oxyscape, and we addressed the importance of considering the oxyscape in the modelling and managing of aquatic ecosystems.

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.
This manuscript presents the iron (Fe) concentrations and isotopic compositions of seawater...
