From: The effect of tidal forcing on biogeochemical processes in intertidal salt marsh sediments
Average concentrations of Fe2+ and ΣH2S measured in situ during tidal cycles as a function of depth at: a) the mud flat site; and b) the creek bank site. The standard deviations represent temporal variations from the average concentration during tidal cycles. The number of tidal cycles during which concentrations were measured and the date of these measurements are provided above each data set.
