Job description:

The Alfred Wegener Institute Helmholtz Centre for Polar and Marine Research (AWI) is a member of the Helmholtz Association (HGF) and funded by federal and state government. AWI focuses on polar and marine research in a variety of disciplines such as biology, oceanography, geology, geochemistry and geophysics thus allowing multidisciplinary approaches to scientific goals.

The department of Climate Science, section of Sea Ice Physics, located in Bremerhaven, invites applications for the position as

PostDoc in sea ice physics

on ‘solar radiation and sea ice - observations and process modelling’ as part of the BMBF funded project DiatomARCTIC, a contribution to the NERC/BMBF initiative the ‘Changing Arctic Ocean’ (CAO, )

You shall approach the theme by a combination of field measurements and numerical process modeling. The aim is to improve our understanding of the impacts of actual and future sea ice, snow, and ocean conditions on the ecosystem, down to the level of algae species. Work will focus on improving and adapting a 1D biogeochemical sea ice model (BFM-SI) based on field observations from a remotely operated vehicle (ROV) and autonomous platforms (buoys) in collaboration with partners in Finland and the UK. Simulations will be performed and analyzed on seasonal time scales, but also include applications towards climate scenarios and future changes.


·       Establish and operate the existing sea ice model (BFM-SI) in our working group

·       Derive improved parameterizations for spectral light transfer through snow and sea ice, based on observational data from different Arctic regions and sea ice conditions.

·       Perform sensitivity studies of environmental parameters and their role for energy budgets and species-specific algal productivity.

·       Analyze model results and field observations with respect to biological processes in close collaboration with our project and other international partners.

·       Publication of results in peer-reviewed scientific journals.

·       Tight collaboration within the project with our partners from UK and Finland, including workshops, reports, and responsibilities for deliverables.

·       Possibly participate in the upcoming MOSAiC field experiment ( in connection to the ROV and bio-physical work.

We are looking for a highly motivated, outstanding researcher, who enjoys working in a team and has good English communication skills. You must hold a PhD or equivalent degree in Physics, Geophysics or a related field. Experience in scientific programming and handling of observational data is expected. Also a good knowledge of radiative transfer theory will be an essential criterium. Experience in polar sea ice processes and bio-physical sea ice modeling is of advantage. A further advantage is experience in polar field work with a strong interest in technical applications.

For further information please contact Dr. Marcel Nicolaus (, +49(471)4831-2905) or Prof. Dr. Christian Haas (, +49(471)4831-2285).

The position is limited to 2.5 years, starting at the earliest convenient time, but latest 01 January 2019. The salary will be paid in accordance with the German Tarifvertrag des öffentlichen Dienstes (TVöD Bund), salary level 13. The place of employment will be Bremerhaven.

We offer you a multi-disciplinary, international, and fascinating professional environment with flexible working hours, state-of-the-art research equipment, and a first-rate infrastructure.

AWI aims to increase the number of women in the scientific staff and therefore encourages women to apply. Disabled applicants will be given preference when equal qualifications are present. The AWI fosters the compatibility of work and family through various means. Because of our engagement in the area of work-life compatibility we have been awarded the certificate “Career and Family”.

Please forward your applications with the standard documentation (CV, degree certificates, a statement of research interests copies of certificates, publications and contact details of two references) by September 21th 2018 referencing code 129/D/Kli by e-mail (all documents merged into one PDF file) to:
