LEDIG STILLING VED UIT NORGES ARKTISKE UNIVERSITET
PhD Fellow in Theoretical Seismology
Deadline: 05.01.2025
Publisert
UiT The Arctic University of Norway is a multi-campus comprehensive university at the international forefront. Our vision is to be a driving force for developing the High North. The Northern Sami notion eallju, which means eagerness to work, sets the tone for this motive power at UiT. Along with students, staff and the wider community, we aim to utilise our location in Northern Norway and Sápmi, our broad and diverse research and study portfolio and interdisciplinary advantage to shape the future.
Our social mission is to provide research-based education of high quality, perform artistic development and carry out research of the highest international quality standards in the entire range from basic to applied. We will convey knowledge about disciplines and contribute to innovation. Our social mission unites UiT across various studies, research fields and large geographical distances. This demands good cooperation with trade and industry and civil society as well as with international partners. We will strengthen knowledge-based and sustainable development at a regional, national and international level.
Academic freedom and scientific and ethical principles form the basis for all UiT’s activities. Participation, co-determination, transparency and good processes will provide the decision-making basis we need to make wise and far-sighted priorities. Our students and staff will have the opportunity to develop their abilities and potential. Founded on academic integrity, we will be courageous, committed and generous in close contact with disciplines, people and contemporary developments.
We will demonstrate adaptability and seek good and purposeful utilisation of resources, so we are ready to meet the expectations and opportunities of the future. We will strengthen the quality and impact of our disciplines and core tasks through the following three strategic priority areas.
The position is for a period of four years. The nominal length of the PhD programme is three years. The fourth year is distributed as 25 % each year and will consist of teaching and other duties. The objective of the position is to complete research training to the level of a doctoral degree. Admission to the PhD programme is a prerequisite for employment, and the programme period starts on commencement of the position.
This PhD position is part of an ongoing research and teaching collaboration between UiT and NORSAR at Kjeller, Norway. The research aims to develop innovative representations of spatiotemporal random fields and propose new methods for analyzing and interpreting seismological array data.
The workplace is at UiT in Tromsø, but with regular research visits to NORSAR. Participation in fieldwork in mainland Norway and Svalbard may also be necessary. You must be able to start in the position within a reasonable time after receiving the offer.
About the research project
The objective of this PhD project is to establish a novel theoretical framework for extracting near-surface geophysical information from passive recordings of ambient seismic noise. A standard assumption is that the seismic noise wavefield is generated by uniformly distributed random sources, and hence, that the transfer function (Green's function) can be estimated by cross-correlating pairs of seismic sensors over extended time periods. Our aim is to challenge the standard assumptions of homogeneity and stationarity by tailoring state-of-the-art representations of spatiotemporal random fields to seismic waves in inhomogeneous random media.
The starting point will be to formulate seismic wave propagation in random media through the framework of harmonizable random fields. This will give the provision to model temporal non-stationarities in terms of dual-frequency correlations, and spatial inhomogeneities in terms of dual-wavenumber correlations. The PhD student shall be actively involved in formulating the necessary theoretical framework, developing and implementing practical estimators, and testing the methodology on real world data.
Depending on the background and interests of the PhD student, it may be possible to extend the project to also include passive geoelectric self-potential methodology. A joint inversion of passive seismic and geoelectric array data may yield vastly improved tomographic imaging of the subsurface.
The proposed methodology will be evaluated and demonstrated by analyzing a range of pertinent ground motion data. This will include data from seismic arrays, optical fibers (Distributed Acoustic Sensing - DAS and Distributed Temperature Sensing - DTS), and ocean bottom sensors. The primary objective will be to provide high-precision estimates of relative velocity variations (dv/v) in the subsurface, with potential applications to imaging and characterization of key processes in the cryosphere (e.g., glacier and permafrost dynamics), subsurface hydrology, and geohazards.

We will also emphasize motivation and personal suitability for the position.
The successful candidate has:
Good collaboration skills
Good communication and interaction with colleagues and students
A desire to contribute towards a good working environment
As many people as possible should have the opportunity to undertake organized research training. If you already hold a PhD or have equivalent competence, we will not appoint you to this position.
Admission to the PhD programme
For employment in the PhD position, you must be qualified for admission to the PhD programme at the Faculty of Science and Technology and participate in organized doctoral studies within the employment period.
Admission normally requires:
A bachelor's degree of 180 ECTS and a master's degree, or an integrated master's degree.
In order to gain admission to the programme, the candidate must document sufficient potential for research. The applicant must have a grade point average of C (strong 3.0) or better for the master’s degree, which must contain an independent work. A more detailed description of admission requirements can be found here.
