100%, Zurich, fixed-termThe Environmental Physics Group at the Swiss Federal Institute of Technology Zurich (ETH Zurich) seeks a highly motivated Ph.D. student to investigate the global organic carbon budget in marine sediments and the effects of anthropogenic and climatic perturbations. Project backgroundMarine sediments play a critical role in the global carbon cycle, serving as the ultimate sink for carbon by sequestering it in the form of organic carbon (OC) for geological timescales. However, the magnitude of OC buried in marine sediments remains uncertain, and its spatial distribution is still poorly understood. This project aims to understand and quantify the global organic carbon budget in marine sediments and assess the influence of anthropogenic and climatic perturbations. It utilizes spatial machine learning models to determine the carbon budget which also serves to identify the environmental conditions that control the accumulation and remineralization of OC. The project focuses on how direct anthropogenic activities (such as river dams and coastal eutrophication) impact OC deposited in coastal marine sediments, and how climate change in Arctic environments has affected the accumulation of OC in Arctic sediments. Finally, it aims to predict future trends in the global carbon budget under the influence of climate change and anthropogenic perturbations. Job descriptionAs a successful candidate, you will compile and analyze organic carbon and its isotopic composition in specific sites. You will disentangle the environmental processes that drive the accumulation and remineralization of organic carbon in the Arctic using statistical methods. Additionally, you will quantify the contribution of different sources of organic carbon in Arctic sediments and assess how human activities, such as river damming and coastal eutrophication, are affecting organic carbon storage in coastal environments. Moreover, you will predict future changes in the sedimentary organic carbon budget due to intensifying climate change in the Arctic and expanding anthropogenic activities in coastal environments. You will be working in the Environmental Physics Group, an interdisciplinary research group that focuses on studying the ocean, its physics, biogeochemistry, and ecology and their interactions with climate using different modelling techniques, led by Prof. Dr. Nicolas Gruber. In addition, you will conduct a short research stay at the Alfred Wegener Institute (AWI) in Bremerhaven, Germany, with our collaborator, Dr. Gesine Mollenhauer, which will allow you to work with other researchers focused on understanding the carbon cycle in the Arctic.
