What is Trace metals in metalliferous sediments, MANOP Site M: interfacial pore water profiles about?
We present data showing enrichments of metals Mn, Cu, V, Cr, Cd and Ni and dissolved organic matter (DOM) in surficial pore waters, depths < 1 cm, at a metalliferous sediment site in the Pacific. We also present a model of metal release during particulate organic carbon (POC) oxidation and opal dissolution at the sediment-seawater interface. A comparison of measured interracial metal concentrations with those predicted from the model suggest that Cd, Ni and Cr are released during oxidation of POC at the sediment-seawater interface. However, for V, Cu and Mn additional 'source(s)' and/or processes are required to account for the measured interracial concentrations• For Cu, recycling via interracial remineralization and release to bottom waters, with subsequent scavenging out of bottom waters by particulates, probably provides the major additional 'source'• For V, we suggest that, in addition to some contribution from a benthic flux-bottom water scavenging scenario, complexation with DOM at the interface serves as a trap to accumulate V released from particulates in the zone of oxygen reduction• For manganese, we suggest that most of the interracial pore water content is produced fro
