Postdoctoral fellowship on Arctic and Antarctic sea ice-ocean modelling
Université catholique de Louvain 5UCLouvain), Earth and Life Institute (ELI), Georges Lemaître Centre for Earth and Climate Research (TECLIM)
TECLIM has 15 academic staff, 6 administrative/technical staff and about 75 temporary scientific staff (Ph.D. students and postdoctoral researchers). Its research aims to understand the functioning of the Earth system, with emphasis on its climate component, and the interactions between human activities and their natural environment. Current research activities concern (1) past environmental and climate changes, (2) the present state of the Earth and solar systems, (3) human-environment interactions and (4) modelling tools.
TECLIM has a strong reputation in the field of global climate modelling. Using in-house developed ESM of intermediate complexity, the centre conducted seminal studies on the last glacial-interglacial cycles, the abrupt climate change that occurred 8,200 years ago, climate variability during the Holocene (including the last millennium) and future climate changes. The sea ice model (LIM) it built is considered essential in the community of climate and ocean modellers. A large number of original process studies were performed with this model coupled to various ocean general circulation models, especially the Nucleous for European Modelling of the Ocean (NEMO) platform. These studies notably highlighted the key role played by sea ice–ocean interactions in controlling the circulation of the World Ocean. In addition, TECLIM contributed to the coupling of NEMO-LIM to the IPSL-CM and EC-Earth ESMs, and the regional climate models MAR and COSMO-CLM. Over the past decade, it produced several important papers on the mechanisms responsible for past and future climate variability at high latitudes of both hemispheres and on the role of polar oceans and sea ice in observed and projected climate changes. Recently, it embarked on the study of polar climate predictability on seasonal-to-interannual timescales, both under idealized and realistic conditions.

Global climate model simulations still have significant biases in the extent of summer Arctic and Antarctic sea ice. One of the reasons is the coarse resolution of the models, which forbids an adequate representation of the processes that control the evolution of the ice edge, such as the interactions between sea ice and oceanic eddies, the influence of landfast ice, the role of coastal currents, the complex bathymetry, … In this context, the Georges Lemaître Centre for Earth and Climate Research (TECLIM) / Earth and Life Institute (ELI) of the Université catholique de Louvain (UCLouvain), Louvain-la-Neuve, Belgium is seeking a postdoctoral fellow for conducting and comparing thoroughly simulations with the global sea ice-ocean general circulation model NEMO4-SI3 driven by an atmospheric reanalysis at two different horizontal resolutions, namely 1° and 1/12°, in order to determine how resolution impacts the model mean state and the model ability to reproduce the summer sea ice extent record lows observed recently in both the Arctic and Antarctic.
The successful candidate should have a PhD in ocean/sea ice modelling or related fields, and should have published in peer-reviewed scientific international journals. Experience in polar oceanography/glaciology is an asset. Advanced programming, post-processing and data managment/analysis skills are required. He/she should be fluent in English due to the multiple interactions planned with other members of TECLIM and should have demonstrated ability in team working.
The position is offered for 24 months, from September-October 2022 (the exact starting date can be negociated). Note that it is only accessible to researchers who did not spend the last 2 years in a Belgian lab and who have less than 6-yr experience after their PhD thesis defense.
Applicants should send by e-mail to Thierry Fichefet (firstname.lastname@example.org) (i) a statement of research experience, qualification and interest, (ii) a complete CV, including a list of publications, and (iii) the name of two scientists who would agree to write a letter of recommendation. Review of the applications will start on June 15th. The call will remain open until the position is filled.
