Distribution of dissolved iron in Antarctic sea ice: Spatial, seasonal andinterannual variability?
Results from recent field studies in Antarctic sea ice show no clear differences in dissolved iron (dFe) concentrations between pack ice sampled in East Antarctica (2.6-20.5 nmol/L), in the Weddell Sea (0.7-36.8 nmol/L), and in the Bellingshausen Sea (1.1-30.2 nmol/L). Dissolved Fe concentrations we...
