Sea Surfaces


My research interest is carbon and carbonate cycling across aquatic systems including coastal ecosystems (estuaries and continental margins) and polar region with particular emphasis on the exchange of CO2 with the atmosphere and on the coupling between inorganic carbon dynamics and biological processes.
