PhD Candidate in “Multi-temporal remote sensing of dynamic Arctic phenomena”
The Department of Physics and Technology announces a vacant position of a PhD Candidate in the area of multi-temporal, model-supported remote sensing for Arctic applications.
UiT The Arctic University of Norway
UiT – Developing the High North
UiT is a multi-campus research university in Norway and the northernmost university of the world. Our central location in the High North, our broad and diverse research and study portfolio, and our interdisciplinary qualities make us uniquely suited to meet the challenges of the future. At UiT you can explore global issues from a close-up perspective.
Credibility, academic freedom, closeness, creativity and commitment shall be hallmarks of the relationship between our employees, between our employees and our students and between UiT and our partners.
Department of Physics and Technology
The Department of Physics and Technology consists of six research groups: (1) Complex Systems Modelling,(2) Earth Observation, (3) Energy and Climate, (4) Machine Learning, (5) Space Physics, and (6) Ultrasound, Microwaves and Optics (UMO). The department provides education on the Bachelor, Master, and PhD levels, and comprises 22 permanent scientific positions and a technical/administrative staff of 12 persons.
The appointment is for a period of four years. The nominal length of the PhD program is three years. The fourth year is used for teaching or other duties for the department. The duties are normally distributed evenly over the four years.
The successful candidates will work at Centre for Integrated Remote Sensing and Forecasting for Arctic Operations (CIRFA). CIRFA conducts research on integrated remote sensing for Arctic operations by developing data analysis methods and technologies for reliably characterizing and monitoring the physical environment of the Arctic. The Centre also explores methods to efficiently assimilate the derived information into models to perform improved predictions of sea ice state, meteorological and oceanographic conditions. The project is associated with WP2, WP3, and WP5; WP2 conducts research within remote sensing of sea ice, WP3 within remote sensing of oil spills, and and WP5 within weather, ocean, and sea ice prediction as well as drift modelling.

The position’s field of research
With the current availablity of multiple systems of polar orbiting Earth observation satellites, the capability of imaging dynamical phenomena has greatly improved. Remote sensing tasks like classification of drifting sea ice and the detection and characterization of marine oil-spills are dealing with the observation and information extraction of highly dynamic surface targets, i.e. objects with constantly changing locations and areal signatures. In this regard, the time dependent information, if properly used in the data analysis, should improve the effectiveness and reliability of remote sensing products. In ice charting, the use of past classifications can help to generate the next ice charts, and enable detection and characterization of deformation zones. This requires to consider ice movements.
In synthetic aperture radar (SAR), which will be a main sensor in the project, the information in an image is highly dependent on imaging geometry and meteorological conditions. Temporal analysis of classified sea ice scenes can increase understanding of changes in ice type signatures as function of varying environmental and imaging conditions. Similar scenarios can be envisioned in marine oil spill remote sensing. While the past dynamical behavior may be estimated step-wise from time series of the RS images, numerical models can provide continuous predictions of drift and deformation fields. Hence, the field of work of the announced position is to investigate how the combined use of image time series analysis and numerical drift modelling can improve accuracy and relyability in operational services producing sea ice charts and monitoring oil spills.
Roles and responsibilities of the PhD Candidate
The PhD Candidate will work across several work packages in CIRFA: WP2 (Sea ice and iceberg remote sensing), WP3 (Oil spill remote sensing), and WP5 (Numerical modelling). It may also include WP1 (Ocean remote sensing) and WP7 (Pilot services).
The research should include:
- Application of segmentation/classification algorithms to locate the objects of interest in multiple images from synthetic aperture radars (SAR) and/or optical sensors.
- Application of past segmented/classified images to estmate current drift and/or deformation fields, and apply these to obtain “background” information for the next classification .
- Application of drift models to perform numerical predictions of future location and areal appearance of studied surface objects.
- System integration and performance assessment.

- Professor Rune Gravesen, UiT: [email protected]
This position requires a Norwegian master degree in physics, mathematics/statistics, meteorology, oceanography or similar, or a corresponding foreign master degree recognised as equivalent to a Norwegian master degree.
The suitable candidate must have:
- Background in signal and image processing
- Experience with remote sensing data analysis (SAR and/or optical),
- Skills in programming
- Documented fluency in English is required
Knowledge of numerical modelling in meteorology and/or oceanography, pattern recognition and big data processing, plus previous experience in applications related to oil spills, sea ice or icebergs would be advantageous.
Other required qualification skills include:
- Independence and self-motivation
- Creativity and ability to think outside the box
- Excellent work ethics and commitment to the job
- International experience is an advantage. Empasis is also given to personal suitability.
The position requires admission to the PhD programme. Information about requirements and the PhD programme is available here: https://uit.no/nt/phd
During this assessment process, emphasis will be put on your potential for research as shown by the Master’s thesis and any other academic works. In addition, we may consider work experience or other activities of significance for the PhD studies.
We offer an interesting project within a highly invovative centre environment, opportunities to travel and meet other leading scientists within the field, independence in work, a fantastic work environment with nice colleagues, good remuneration, and a cozy hometown of Tromsø surrounded by the stunning landscape of Northern Scandinavia.
Terms of employment
Remuneration of PhD positions are in salary code 1017, and normally start at salary grade 51 on the pay scale for Norwegian state employees. There is a 2% deduction for contribution to the Norwegian Public Service Pension Fund.
