ETZ Zurich is seeking two highly motivated and curious Ph.D. students to join the Environmental Physics Group at ETH Zurich, a vibrant interdisciplinary team of researchers studying the ocean, its physics, biogeochemistry, and ecology and their interactions with climate. A key motivation driving their work is to better understand and quantify how climate change will impact the ocean, its biogeochemistry, and its ecology, and how these changes may feed back on climate. These two positions are offered in the framework of the recently funded Horizon-Europe BioGeoSea project. 

• Ph.D. position 1: The first of the two doctoral students will work primarily on the marine nitrogen cycle and how it is affected by extreme conditions. The focus will be on the production, consumption and outgassing of nitrous oxide (N2O), a very potent greenhouse gas.

• Ph.D. position 2: The second doctoral student will work on the improvement of zooplankton processes in the models, focusing on their role in structuring the phytoplankton community and in governing the efficiency of the biological carbon pump.

The Faculty of Environment, Science and Economy wishes to recruit a Postdoctoral Research Fellow. This exciting Horizon Europe funded post is available immediately until the end of 2028, based in Exeter, UK, in the Department of Geography. They are seeking a motivated and innovative researcher to join Professor Schuster’s group in advancing the knowledge of the ocean’s role in the global carbon cycle. The successful candidate will contribute to the collection, integration, interoperability, and analyses of observations centred on marine carbon cycle variability and its drivers.

The ocean is a powerful contributor to Earth’s climate regulation. It is now absorbing about a quarter of anthropogenic CO2 emissions – besides substantial amounts of heat – every year. Thus, it is one of the key players in moderating atmospheric CO2 and heat buildup and hence the change of climate. However, rising oceanic CO2 levels also significantly alter ocean chemistry and impact critical ecosystem services. Determining these changes requires sustained, long-term high-quality in-situ observations, enabling impactful observation-based analyses informing forecasting ocean and climate models. Meeting these challenges, within the European Horizon Europe projects GEORGE (https://george-project.eu/) and TRICUSO (https://tricuso.eu/), they are advancing technological developments, ocean observations, data integration and analyses through the leading European ocean observing research infrastructures ICOS, EMSO, Euro-Argo, and EMBRC.

This exciting role builds on their research group’s experience and supports international efforts in designing a scientifically robust, feasible, and sustainable observational strategy to monitor oceanic CO2 uptake with improved confidence. Any future observational network utilises a range of instrument/sensor technologies, deployed on different platforms, and measuring multiple variables required to track oceanic CO2 uptake and the drivers of its variability.
