Figure 5From: The effect of tidal forcing on biogeochemical processes in intertidal salt marsh sedimentsPorewater Fe2+, ΣH2S, org-Fe(III)(aq), and FeS(aq) measured in situ as a function of depth with voltammetric Au/Hg microelectrodes at: a) the mud flat site starting at low tide; and b) the creek bank site starting at high tide in the Skidaway salt marsh in October 2002. Mn2+ was not detected in both sediments.Back to article page
