Currently, we are looking to fill the following position within the Geochemistry group at the Department of Earth Sciences:PhD researcher in Biogeochemical Ocean Modeling (1,0 fte)
Description
Modeling Ocean Biogeochemistry in the mid-Cretaceous: reconstructing the nutrient-biosphere-climate linkMassive amounts of organic matter were buried in ocean sediments during mid-Cretaceous Oceanic Anoxic Events (OAEs). As yet, a quantitative understanding of the mechanisms and feedbacks responsible for the perturbation of the oxygen, carbon and nutrient cycles around OAEs is still lacking. In this project, general circulation modeling for the global ocean will be used to elucidate the triggers for global ocean anoxia during the Cenomanian/Turonian (C/T) boundary event (~94 Myrs BP). In particular, the role of changes in riverine inputs and upwelling intensity in determining nutrient availability and oxygen conditions in the Atlantic ocean will be addressed.
Proxy and burial data from a companion project will be used to define model scenarios and to evaluate model results. The results of this study will greatly improve our ability to predict the consequences of current global warming on biogeochemical dynamics and the feedbacks on the biosphere and climate in the modern ocean.Project partners include researchers at the Faculty of Biology and the Institute for Marine and Atmospheric Research (IMAU) in Utrecht and the University of Bergen, Norway. Funding is provided by the Focus and Mass program of the Faculty of Geosciences, Utrecht University.
