Metal-complexing Ligands and Metal Speciation in Sediment Pore Waters: Implications for Sediment/water Exchange and Water Column Speciation

Abstract

LONG-TERM GOALS. Our long-term goals are to determine the role that complexation and speciation play in sediment/water exchange of metals in estuarine and coastal locations, and the importance of metal-complexing ligands fluxing out of estuarine pore waters to water column metal speciation on local, regional, and global scales. OBJECTIVES. Our scientific objectives are to determine: (1) the extent of complexation and the speciation of selected trace metals in bottom waters and sediment pore waters; (2) concentrations and strengths of metal ligands in bottom waters and sediment pore waters; (3) the magnitude and direction of the benthic flux of metals and their ligands; and (4) the lifetime of the metal ligands fluxing out of pore waters into overlying bottom waters and their degradation and removal processes.
