GEOMAR Helmholtz Centre for Ocean Research Kiel is a foundation under public law jointly financed by the Federal Republic of Germany (90%) and the State of Schleswig-Holstein (10%). It is one of the internationally leading institutions in the field of marine research.

Through our research and our commitment to the transfer of knowledge and technology, we contribute significantly to the preservation of the function and protection of the ocean for future generations.

The Synergy Project WHIRLS funded by the European Research Council (ERC) researches the role of ocean fine-scale whirls on climate and ecosystems. The focus is on the Agulhas Current System around South Africa as a global hotspot of eddy activity, ocean-atmosphere heat exchange, and marine productivity. Multiple coordinated observing strategies, including research vessels and a large ensemble of autonomous platforms, will collect physical, chemical, and biological datasets across scales. The research group at GEOMAR complements these data and researches the role of fine-scale eddies by using high-resolution models of the ocean and the atmosphere. WHIRLS consists of 4 partners in France, Sweden, South Africa, and Germany.

In the frame of WHIRLS, the research unit Ocean Dynamics of the research division Ocean Circulation and Climate Dynamics offers a position as a

starting as soon as possible.

The position offers the possibility to attain a doctoral degree in natural sciences.

Job Description

We are seeking a highly motivated and PhD candidate (doctoral researcher) to enhance our research group. The candidate shall provide to the numerical modelling, the analysis and interpretation of coupled atmosphere-ocean models on the basis on NEMO-OpenIFS. The main emphasis is on the role of the (sub)mesoscale for the exchange between atmosphere and ocean, the oceanic uptake of heat and trace gases, and the role of fine-scale processes for weather and climate. The candidate will work in a team of scientists and numerical modeller at GEOMAR, also in the framework of international collaborators within WHIRLS.
