Abstract

ANY exposure of anoxic estuarine sediments to the atmosphere during sample handling and processing can lead to decreased values of ferrous iron1, reactive phosphate2 and reactive silicate3 in the pore waters of these sediments. Thus, the mishandling of anaerobic sediments and their pore fluids will in turn lower calculated diffusional fluxes of these compounds from the sediments into the overlying water. To date, this oxidation effect has only been documented for clastic sediments rich in iron. We present data here which indicate that a similar phenomenon occurs when anoxic iron-poor, carbonate-rich sediments are exposed to an oxidising milieu.
