The position

The Department of Physics and Technology is excited to announce a vacant position of Postdoctoral Research Fellow in the area of sea ice model parameter optimization with Earth Observation data at UiT The Arctic University of Norway, Faculty of Science and Technology. The position is connected to the Nansen Environmental and Remote Sensing Centre (NERSC) in Bergen.

General information about the position.

The position is a fixed term position for a duration of 3 years. Appointment to the position of Postdoctoral Research Fellow is mainly intended to provide qualification for work in top academic positions. It is a prerequisite that the applicant can carry out the project over the full course of the employment period. No person may hold more than one fixed term position as a Postdoctoral Research Fellow at the same institution.

If you successfully apply for a personal overseas research grant from NFR it is possible to extend the fellowship period corresponding to the length of the stay abroad (minimum three months, maximum 12 months).

The workplace is at UiT in Tromsø. You must be able to start in the position within a reasonable time after receiving the offer.

The project

The position is funded by the Norwegian Research Council (NFR) Grant: DynAMIC (Detecting episodes of Arctic sea ice Mass Imbalance). DynAMIC aims to observe three-dimensional changes in the Arctic’s sea ice cover from a multi-sensor constellation of satellites, developing a system for detecting rapid sea ice mass changes driven by deformation, and enabling updates to the constraints on sea ice model redistribution schemes for a new Arctic dominated by seasonal ice. The project is a partnership between UiT The Arctic University of Norway and the Norwegian Polar Institute (NPI) in Tromso, and NERSC in Bergen, with collaboration partners in France, the UK and US.

Work Package (WP) 1 of DynAMIC will deliver high-resolution sea ice thickness distributions (ITDs) from satellite altimetry for the period between 2018-2024 when many polar-orbiting spaceborne altimeter and SAR sensors have been operating together. A PhD Student on WPs 1 & 2 in the project will match these ITDs to maps of sea ice deformation and linear kinematic feature (LKF) evolution observed with SAR, to detect changes in the ITD caused by sea ice divergence and convergence, during Arctic storm events.

This Postdoctoral position fits into WPs 2 & 3 of DynAMIC. The researcher will prepare and use the spaceborne altimetry and SAR observations to optimize the sea ice redistribution transfer function parameters in a single-column version of the ICEPACK model. A set of sensitivity experiments will be performed to identify the modelled change in ITD that best matches the altimetry observations, over a case study deformation event, based on the integrated strain rate observed from SAR. These experiments will be repeated for a database of events covering different sea ice types, conditions, locations, and rates of ice deformation (from docile to violent). Machine learning techniques will then be used to find a global functional parameter set, from the single-column experiment results, that offers the best performance for the model redistribution scheme in modern Arctic conditions.

Results from the work will feed directly into WP3 of DynAMIC, led by NERSC, to investigate pan-Arctic patterns in the sea ice deformation field and LKFs, with a newly-incorporated ridging scheme in the state-of-the-art neXtSIM: next-generation sea-ice model.

The postdoc will work directly with other members of the DynAMIC team, including project investigators and the PhD Student. The candidate will further join a growing team of researchers studying polar sea ice within the Earth Observation Group at the UiT Department of Science and Technology

The role of the position

The candidate will be required to take on a leadership role within the associated NFR project, including collaboration with project partners, participation in project meetings, communication & dissemination at conferences, and contribution to reporting.

The candidate will participate in research towards some of the following project work; however, there is flexibility for the candidate to propose and direct their own research:

Set up the ICEPACK model to run at UiT
Prepare a set of case study “deformation events” from the spaceborne altimetry and SAR observations delivered by other project members, matched to forcing data from atmospheric reanalyses
Perform model sensitivity experiments on the case studies to generate a range of scenarios for the evolution of the ITD under prescribed forcing, with different parameterizations for the sea ice redistribution transfer function
Apply machine learning methods to identify optimal model parameters that can be used in large-scale sea ice simulations (either global parameters, or as a function of existing model variables like ice thickness)
Work with colleagues at NERSC to set up pan-Arctic neXtSIM runs with a constrained sea ice redistribution function and support them in studying the impacts on sea ice convergence fields and LKF evolution
Prepare peer-review publications to disseminate the results

About the workplace

UiT The Arctic University of Norway, with its main campus located in Tromsø, is the northernmost university in the world. Its focus on climate and environment is clearly dictated by the geographical location at the edge of the Arctic. The main task of the Faculty of Science and Technology is to conduct research and teaching at high national and international level. Prioritized research areas include energy, climate, environment, maritime, marine, nano-, space-, and information technology, addressing both general topics and topics relevant for the High North.

The Department of Physics and Technology consists of six research groups: Earth Observation, Renewable energy, Machine Learning, Complex Systems Modelling, Space Physics, and Ultrasound, Microwaves and Optics. The department provides education at the Bachelor, Master, and PhD levels.
