Abstract:

Our long-term goals are to determine the role that complexation and speciation play in the sedimentwater exchange of metals in estuarine and coastal locations, and the importance of metalcomplexing ligands fluxing from estuarine porewaters to water column metal speciation on local, regional, and global scales. Our scientific objectives are to determine 1 the extent of complexation and the speciation of selected trace metals in bottom waters and sediment porewaters 2 concentrations and strengths of metalcomplexing ligands in bottom waters and sediment porewaters 3 the magnitude and direction of the benthic flux of metals and their ligands and 4 the persistence of the ligands fluxing out of porewaters into overlying bottom waters and their degradation and removal processes.
