Fig. 5: Concentrations of ascorbate-extractable Fe (FeA) and dissolved iron over sediment depth at three stations within the transects.

The three frames show the amount of FeA and the concentration of dissolved iron (dFe(II)) in the pore water versus sediment depth at a stations closest to the fjord head (Kongsfjorden (KFa) = KFa1, Lilliehöökfjorden (LF) = LF1, Dicksonfjorden (DF) = DF1); b mid-fjord stations (KFa = KFa5, LF = LF5, DF = DF3); and c: stations closest to the fjord mouth (KFa = KFa7, LF = LF8, DF = DF5).
