My research interests are marine carbon and nutrient cycling with emphasis on inorganic carbonate chemistry (TA, DIC, pH, pCO2), air-sea fluxes of climate relevant gases (CO2, CH4) and the development of sensors and methods to study carbonate system dynamics.
My PhD research focused on the factors influencing the strength and efficiency of the carbon pump in the northern Benguela upwelling system (NBUS) off the southwest African coast. The coastal surface water of upwelling systems is naturally eutrophied, oxygen‐depleted, carbon dioxide‐enriched and acidified, which makes them natural “labs” to study carbon and nutrient cycling under scenarios which are, among others, projected as main threats in the future. I investigated the dynamics of carbonate saturation and their effects on the magnitude and composition of (carbonate) particle export to the shelf. Along with patterns of air-sea CO2 fluxes, they provided a basis to assess the net C source-sink function of the BUS, which was the major objective of my PhD research.
For my postdoctoral research at NOCS, I am involved in the STEMM-CCS project and will be working on assessing the applicability of natural and artificial tracers for the detection of CO2 leakages.
