Dissolved iron measurements from 44 stations in the shallow Arctic Ocean waters and Shelf Sea's during POLARSTERN cruise ARK-XXII/2 ...
Concentrations of dissolved (<0.2 µm) Fe (DFe) in the Arctic shelf seas and in the surface waters of the central Arctic Ocean are presented. In the Barents and Kara seas, near-surface DFe minima indicate depletion of DFe by phytoplankton growth. Below the surface, lower DFe concentrations in the...
