- Marine chemistry and biogeochemistry of trace metals
- Tel: (03) 479 7917
- Location: Science II, 5c4
Main research interests
- Chemical equilibria in marine and fresh waters, particularly involving CO2; measurement techniques for the CO2 equilibrium system in seawater.
- Trace metals in natural waters and their interactions with phytoplankton; analytical techniques for trace metals; trace metal speciation in natural waters.
- Colloids and surfaces in marine and freshwater systems; the sea-surface microlayer; mechanisms and kinetics of colloid aggregation.
Current Research Projects
- Trace metal speciation in lake waters and the production of strong, metal-binding ligands by phytoplankton (PGSF funded, with S.G. Sander).
- Colloid aggregation in estuaries (PGSF funded, with J.P. Kim & U. Nowostawska).
- CO2 properties of seawater and ocean acidification (with K.C. Currie, C.L. Hurd, C. McGraw and M. Reid).
- Equilibrium constants for H2CO3 and the effect of borate (MSc, H. Doyle).
- Origin of Fe-binding organic ligands in seawater (with E. Ibisanmi, S.G. Sander and P.W. Boyd).
- Calibrating the cadmium paeloproxy: Cd uptake by phytoplankton and effects on Cd isotopic composition (Marsden grant, with M. Gault-Ringold, C. Stirling and R. Strzepek).
- Marine siderophores: structure and function (with I. Velasquez, S.G. Sander and G. Cook).
- Application of MC-ICPMS techniques to determine the sources of metal ion pollution in aquatic systems (with M. Numata, M. Poffet and C. Stirling).
- Virus hitchhikers: is virus transport through aquifers accelerated by colloids? (Marsden grant, with G. Walsh and Liping Pang, ESR).
