My interest centers :
Atmospheric nutrient supply to the oceans; influences on iron solubility in aerosol, in particular in desert dust

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 and iron) 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 dissolves in rainwater then in seawater as this is the fraction which helps to fuel phytoplankton growth. My works are more specifically focused on the iron-bearing dust and its solubility.
