Small-scale ocean processes play an important role in shaping ocean circulation and freshwater distribution in the Arctic. Yet, they remain difficult to observe and represent in numerical models. This limits our ability to understand and predict the ocean and its response to a changing climate. SWOT (Surface Water and Ocean Topography) provides high-resolution observations of sea-surface height that can be used to better constrain these processes and the ocean state.

Responsibilities and qualifications
This PhD will focus on assimilating SWOT observations into a high-resolution ocean model with a focus on the Polar Regions. An emphasis will be on developing surrogate models using Scientific Machine learning to reduce the computational cost of simulations and enable efficient prediction and exploration of ocean processes.

The candidate is expected to have a background in ocean modelling and remote sensing, preferably with experience in satellite altimetry and ocean modelling using the MITgcm (MIT’s General Circulation modelling framework).

The candidate will work in a stimulating environment at DTU Space, with close collaboration with SWOT researchers, other DTU departments, and international partners. The candidate should be motivated to work in an international environment and participate in relevant research travel.

You must have a two-year master's degree (120 ECTS points) or a similar degree with an academic level equivalent to a two-year master's degree.

Approval and Enrolment
The scholarship for the PhD degree is subject to academic approval, and the candidate will be enrolled in one of the general degree programmes at DTU. For information about our enrolment requirements and the general planning of the PhD study program, please see DTU's rules for the PhD education.

Assessment
The assessment will be made by Professor Ole B. Andersen. The assessor is also expected to be your main supervisor. A co-supervisor will also be involved.
