RESEARCH INTERESTS

Development and implementation of novel analytical chemistry techniques for the underway determination of trace elements and nutrients on board ship using: gas chromatography, flow injection analysis and development of new programmable flow injection methods for use at sea. Use of these and other techniques to develop large-scale surface water trace element distributions to identify and quantify dust deposition to the surface oceans and its biogeochemical consequences. Use of trace elements to identify and trace biogeochemical and physical pathways in the oceans. Determination of the chemical abundance of key trace elements in other natural materials e.g. rivers, rain, hydrothermal fluids and the aqueous digests of rocks etc., to develop a holistic understanding of global geochemical cycles. Development of a Hadal profiler capable of reaching the bottom of the ocean’s trenches and collecting water samples within the trenches to constrain our understanding of their ventilation mechanisms.
