| Summary: | Data from Polarstern cruise PS94 in the Arctic in 2015 with chief scientist Ursula Schauer. In order to explain geochemical cycles of Fe in the ocean, M. Rijkenberg, L. Gerringa and H. Slagter samples filtered seawater using an ultra clean titanium CTD. In these samples on board measurements were executed: Dissolved Fe by flow injection analysis and the characteristics of the dissolved organic Fe-binding organic ligands (totalL), being the concentration of these ligands and the conditional binding constant of the Fe-complex (K expressed as its logarithm: logK). Moreover in order to relate the dissolved organic Fe-binding organic ligands to humic substances fluorescence of dissolved organic matter was measured as well as humic substances using voltammetry. |
