From: The effect of tidal forcing on biogeochemical processes in intertidal salt marsh sediments
Porewater O2(aq), Mn2+, Fe2+, ΣH2S, org-Fe(III)(aq), FeS(aq), and ΣPO43-, and ascorbate- and dithionite-extractable Fe as a function of depth in sediment cores collected ex situ at the creek bank site in the Skidaway Salt marsh at: a) High tide; b) Low tide; and c) Rising tide over a 24 hour period in June 2002. Acid volatile sulfide (AVS) was quantified in the low tide sediment core only.
