University of Gothenburg offer a PhD position at the Department of Marine Sciences.

The Department of Marine Sciences, the Faculty of Science, University of Gothenburg, was recently launched (July 1, 2015) with the purpose to achieve the vision of “A University of marine research, teaching and cooperation of the highest international class”. The department has about 160 employees – researchers, teachers, students, technicians and administrators. The department carries out teaching and research in the various marine specializations, biology, oceanography, chemistry, and marine geology. Research is conducted both within specialized individual projects as well as within larger interdisciplinary programs. The Department is situated in Gothenburg and at the University’s research stations at Tjärnö and Kristineberg. The current position is placed in Gothenburg.

Project: Shelf slope dynamics in the Sea of Oman – how submesoscale processes control food and water security.

This project aims to resolve the submesoscale processes which cause important and destabilizing harmful algal blooms (HAB) in the Gulf region. While the physical dynamics of the Sea of Oman are well resolved on meso- and basin-scales, the coupling between the basin circulation and shelf processes responsible for HAB generation is not well understood. The main drivers for local upwelling and the exchange of water and its properties across the shelf break are not fully resolved. In particular, the relative importance of the two dominant causes of upwelling (Ekman dynamics and eddy-topography interactions) and their interactions with the local Persian Gulf Water slope-current are not known. Cross-shelf coupling is strongly determined by processes on the sub-mesoscale with weak surface signatures preventing analysis through remote sensing. The high system complexity and the lack of adequate observations explain past difficulties in resolving cross-shelf transport and local upwelling responsible for HAB.

To address this challenge, we are deploying autonomous vehicles and a mooring array along and across the shelf edge to obtain a long-term high resolution physical and biochemical dataset capturing the process behind cross-shelf exchanges and HAB generation. We aim to identify how basin scale processes interact with both complex topography and the outflow from the Persian Gulf to modulate exchange and ageostrophic transport across the shelf edge. Specifically, we will assess how Ekman dynamics versus eddy-topography interactions control the intensity and extent of upwelling, the nature of upwelled water, and whether this water is transported on-shore leading to HABs. Resolving cross-scale coupling across the shelf edge is crucial to understanding implications for water and food security in this strategic region.

Job assignments

The successful candidate will contribute to our understanding of the underlying physical processes that control HAB generation in the region. More specifically, the PhD student will:

  • Assemble, quality control and process the successive SeaExplorer glider datasets, including the onboard ADCP data.
  • Analyse the glider data in the context of existing remote sensing and model data, and in combination with the deployed ADCP mooring to identify the multiscale physical processes triggering HABs.
  • Identify and investigate the principal drivers of upwelling and cross-shelf transport of water from the oxygen minimum zone.
  • Investigate how meso- to submesoscale ocean processes are responsible for the discrepancy between observed and modelled cross-shelf transport and HAB occurrence; and how these processes play a dominant role in vertical and horizontal transport of oxygen and carbon between the deeper oxygen minimum zone and the shallow coastal shelf region.

The PhD student’s main tasks are listed above. In addition, participation in fieldwork in Oman and remotely piloting the autonomous vehicles will be an important part of the project. The PhD student is expected to show independence, critical thinking and initiative during his/her studies.

The PhD supervisory team will consist of Drs. Bastien Queste and Sebastiaan Swart.

Third cycle education

Admission to third cycle education is aiming at a PhD in Natural Science, specializing in Physical Oceanography The education runs for four years of fulltime studies, containing three years of thesis work and one year of academic education (i.e. course work and literature studies). A selection of courses at the Department/Faculty is available, but national/international courses can also be selected.  You will be employed at University of Gothenburg, and salary follows the regulations at University of Gothenburg.

In addition to pursuing its his/her own research, PhD students are offered to teach, and contribute in the various boards of the department which extends the contract to the same extent-.

Eligibility

The qualifications for education on a doctoral level are: either degree in advanced level, or at least 240 ECTS, of which 60 are on an advanced level, or in another way acquired similar knowledge.

Upon appointment the degree of ability to successfully complete the PhD program will first be evaluated. Only applicants who are admitted to the PhD program at the Dep. of Marine Sciences may be hired.

Assessment

Regulations for the evaluation of qualifications for education on a doctoral level are given in SFS 1998:80. The main assessment is a judgement for the applicant to successfully complete the PhD education.

Qualification/merits

  • Master degree or similar in physical oceanography or related field (physics, data analysis)
  • Experience with scientific programming skills (Python or similar) is essential
  • Ability to process and analyse large datasets is highly desirable
  • Experience in glider data is highly desirable
  • Demonstrated verbal and written communication skills in English
