The long-term goals of our research have been to 1 Continue to develop and evaluate highly sensitive analytical techniques for determining the concentrations of bioactive trace metals in seawater and the extent of their complexation or chelation by natural organic ligands. 2 Further our basic understanding of the role of chemical speciation with respect to both trace metal toxicity and bio-limitation of phytoplankton within coastal and estuarine environments for a suite of bioactive trace metals--Mn, Fe, Ni, Cu, Zn, Cd and Pb. This includes the influence of organic complexation on the reactivity of these trace metals, as well as gaining insight into the production and fate of the metal chelating organic ligands. This research has been particularly complementary to that of Bill Sunda, another Harbor Processes PI, by providing the field data needed to evaluate the applicability of his laboratory studies examining the effects of these trace metals.
