About the Programme
Utrecht University’s Department of Earth Sciences invites applications for a fully funded PhD position focused on Modelling of Ocean Alkalinity Dynamics. This project plays a key role in understanding how ocean alkalinity influences carbon uptake, buffering capacity, and calcium carbonate cycling—essential for predicting future climate feedbacks. The PhD candidate will join the 10-year EMBRACER programme, funded by the Dutch Research Council (NWO), which brings together world-class experts in ocean, land, ice, and atmospheric systems. You will be supervised by Prof. Jack Middelburg and Prof. Henk Dijkstra and work within a collaborative, interdisciplinary environment with access to high-performance computing facilities and state-of-the-art infrastructure. A tailored training plan will support your academic development, and you will also contribute to teaching in the Bachelor’s and Master’s programmes at the university.
