(Table 2) Dissolved iron concentration and ligand characteristics during POLARSTERN expedition ANT-XXIV/3

DOI

The standard deviation for Fe concentrations is missing when there were not enough samples to determine the concentration in duplicate or triplicate. When the [dFe] was not determined in the same sample and therefore the concentration [dFe] was averaged from the samples above and under it; this was used for the calculation of the ligand characteristics.At station 101 the deepest samples collected at 3505 and 4353 m had higher values of dissolved Fe, 0.630 and 0.572 nM, respectively, as compared with the duplicate subsamples reported by Klunder et al. (2011), 0.401 and 0.280 nM, respectively. The cause for this discrepancy is not known; perhaps our samples were contaminated. Nevertheless here we use our values, 0.63 and 0.572 nM in further interpretation. At station 178 Klunder et al. (2011) measured a complete vertical profile and found elevated concentrations of dissolved Fe between 300 and 800 m depth due to melted ice (1.50 nM of Fe at 451 m). The cause for the discrepancy with our sample at 451 m (0.171 nM) is not known.
