Biography

I am a chemist by training, but developed a strong interest in the oceans during my undergraduate degree.  During my PhD, most of which was completed at Plymouth Marine Laboratory, I studied the chemistry of complex natural organic matter in estuarine conditions.  I then went on to investigate the fate of similar organic materials during alumina recovery from bauxite at the University of the West Indies in Jamaica.  After returning to the UK, I spent some time at the University of Liverpool working on the analysis of iron and other trace metals in seawater.  In 1997 I moved to the University of East Anglia, where my research interests have developed into the fields of marine and atmospheric iodine biogeochemistry and the atmospheric transport of nutrients and trace metals and their impact on the marine carbon cycle.

Key Research Interests

My current research focuses on the chemistry of interactions between the atmosphere and the surface of the ocean.  A major part of this involves a study of deposition in aerosols and rain of nutrients (nitrogen, phosphorus, silicon, iron and other trace metals) to the ocean, in order to assess their impact on marine productivity and hence the global carbon cycle.  On a global scale, iron is the nutrient for which atmospheric inputs to the ocean have the most significant impact on phytoplankton growth.  I study the factors that control how much of the iron that falls into the ocean actually dissolves in seawater as this is the fraction which helps to fuel phytoplankton growth.  My other main research area involves the study of iodine cycling in the marine atmosphere (where iodine chemistry influences ozone destruction and new aerosol formation) and in seawater (where the metabolism of iodine by algae is linked to the flux of iodine from the ocean into the atmosphere).
