PhD position "Polar climate change and mesoscale sea ice and ocean

processes" (m/f/d)

Background The Climate Dynamics section at the Alfred Wegener Institute Helmholtz Centre for Polar and Marine Research (AWI) in Bremerhaven, Germany, invites applications for a PhD student position in the field of eddy-rich climate modelling with a focus on polar regions.

You will work with some of the leading European climate modellers and IT experts in the EU Horizon Europe project “European Eddy-rich Earth System Models (EERIE)” on building, running and analysing a new generation of Earth System Models that are capable of explicitly representing a crucially important, yet unexplored regime of the Earth system – the ocean mesoscale (~10 km at the equator to few km at high latitudes).

Tasks You will be part of a team responsible for analyzing eddy-rich climate change simulations (1950–2100) with the IFS-FESOM model. More specifically, you will analyze how polar mesoscale sea ice (e.g., leads) and ocean processes (e.g., eddies) change in a warming world, and how they impact large-scale changes – including interhemispheric asymmetries and possible climate surprises (i.e., eddy-rich simulations lie outside the range of previous CMIP simulations). This will also include the development and application of novel diagnostic techniques that can be used to quantify, understand and evaluate mesoscale sea ice and ocean processes along with their impact on climate. On the more administrative side you will also contribute to reporting activities.


A master in climate science, atmospheric physics, oceanography, physics, informatics or a related field is required (excellent or very good grading). In-depth knowledge of at least one programming language (e.g., Python or R) is also expected. Furthermore, excellent English skills, both written and spoken, are required. Given that the success of this project hinges on effective collaboration between partners, strong communication skills and the ability to work in teams are both a necessity.

Having some of the following skills would be a distinct advantage:

  • Demonstrated skill/proficiency in working with climate models (development, running and/or analysis)
  • Experience with Unix systems
  • Good understanding of climate dynamics, especially related to sea ice and ocean processes
  • Experience with HPC systems
  • Experience in publishing research in peer-reviewed journals
  • Presentation of results in front of peers and the general public
  • Experience with publishing datasets and software
  • Further Information

    Please contact Prof Thomas Jun g (; +49 15146722091) or Dr Nikolay Kolduno v (, @oceanographer on Twitter)for further information.

    This position is limited to 3 years. The salary will be paid in accordance with the Collective Agreement for the Public Service of the Federation (Tarifvertrag des öffentlichen Dienstes, TVöD Bund), up to salary level 13 (66%). The place of employment will be Bremerhaven. All doctoral candidates will be members of AWI's postgraduate program POLMAR or another graduate school and thus benefit from a comprehensive training program and extensive support measures.

    The AWI is characterised by

  • our scientific success - excellent research
  • collaboration and cooperation - intra-institute, national and international, interdisciplinary
  • opportunities to develop – on the job, aiming at other positions and beyond AWI
  • a culture of reconciling work and family – an audited and well-supported aspect of our operation

  • our outstanding research infrastructure – ships, stations, aircraft, laboratories and more

  • an international environment – everyday contacts with people from all over the world
  • having an influence – fundamental research with social and political relevance
  • flat hierarchies – facilitating freedom and responsibility
  • exciting science topics, with opportunities also in technology, administration and infrastructure
  • Equal opportunities are an integral part of our personnel policy. The AWI aims to increase the number of female employees and therefore strongly encourages qualified women to apply.

    AWI offers the possibility of mobile working to the extent of up to 50% of regular working hours.

    Disabled applicants will be given preference when equal qualifications are present.

    The AWI fosters the compatibility of work and family in various ways and has received a number of awards as a result of this engagement.

    We look forward to your application!

    Please submit your application by January 31 st 2023, exclusively online. Reference number: 23/7/D/Kli-b
