PhD Position in Ocean - Sea Ice Interactions

Deploy detailed models of coupled ocean / sea ice processes, probe their turbulent interactions, compare with observations, and design parameterizations for global climate models.

The past decades have been associated with substantial losses of sea ice over both hemispheres. Existing climate models are currently unable to accurately forecast these changes, in part due to their imperfect representation of ocean and sea ice interactions at sub-grid scales.

This project aims to improve our physical understanding of these fine-scale processes, including the melting and breakage of sea ice, using a framework consisting of an ocean Large Eddy Simulation (LES) and a Discrete Element Model (DEM) of sea ice. Results from these simulations will be validated against a combination of in-situ and remote sensing data from both the Arctic and Antarctic sea ice regions.

Based on this new understanding, the candidate will develop parameterizations that can emulate these physics for use in more coarsely-resolved climate models.

This fully-funded position is part of the European Research Council (ERC) 'ICE-FLOE' project, and will involve collaborations with other team members at TU Delft and internationally. There may also be the opportunity to assist with a research cruise in Antarctica.

• Master's degree in Earth sciences, oceanography, physics, applied mathematics, or engineering.
• Demonstrated research experience in climate, oceanography, the cryosphere, or atmospheric science.
• Interest in the intersection of solid/fluid mechanics.
• Experience working with the Julia programming language is an advantage but not required.
• Ability to work independently.
• Excellent command of written and spoken English.
• Ability to start the position in January-March 2027 (with some flexibility).

Working at TU Delft means contributing to solutions that really make a difference.

For over 180 years, we have been training engineers who make an impact worldwide in companies, government bodies, or as entrepreneurs. Our alumni turn knowledge into concrete solutions for the challenges of today and tomorrow.

These challenges are changing rapidly. That is why we focus on themes such as energy, climate, digitalisation, artificial intelligence (AI), and smart mobility every day. Our education and research are directly aligned with what society needs now and in the future.

At TU Delft, our people make the difference. With their knowledge and curiosity, our staff provide a high-quality education and conduct pioneering research that extends beyond the campus. You will have the opportunity to take the initiative, work with others, and grow as a professional.

Working at TU Delft means join an international community of professionals and students. Together, we create knowledge, innovations, and solutions that help move the world forward.
