Thermophilic spore-forming microorganisms in Arctic sediment archives

项目介绍

Stockholm University is a leading European university in one of the world’s most dynamic capitals. The University has more than 33 000 students, 1600 doctoral students and 5500 staff members active within natural science and human science.

The Department of Geological Sciences is a department within the Faculty of Science with about 70 employees and 1000 students. The department supports a broad range of basic research within marine geology, geochemistry and classical geology.

Project description
The aim of the PhD project is to investigate the distribution and abundance of resting stages of thermophilic microorganisms in Arctic sediment archives. The purpose of the work is to explore, through experimental incubation studies, microscopy, and organic biomarker and molecular genetic sequence analysis, their identity, function, and abundance. Metabolic characteristics and sequence information of these organisms should provide clues on present and past thermogenic fluid and gas transport.

One of the goals of the study is to explore whether spores of thermophilic microorganisms can be exploited as paleocurrent indicators and for reconstruction of biogeographic dispersal by currents. In the current project, three hypotheses will be tested:

  1. Thermophilic, sulfate-reducing endospores are present in sediment of the central Arctic basin and sediment cores from the Siberian shelf
  2. The molecular genetic composition of activated spores allows discrimination of local sources in the Arctic Ocean, as opposed to a cosmopolitan identity
  3. The combined information from abundance, induced metabolic activity, and genetic identity of spores in sediment core records can be used to infer source areas and thereby geological Arctic water circulation patterns, i.e, they can be used as palaeoceanographic tracers.

In this project participation in one or several open-ocean ship expeditions to obtain sediment material is expected.

Qualification requirements
In order to meet the general entry requirements, the applicant must have completed a second-cycle degree, completed courses equivalent to at least 240 higher education credits, of which 60 credits must be in the second cycle, or have otherwise acquired equivalent knowledge in Sweden or elsewhere.

The academic area board may permit an exemption from the general entry requirements for an individual applicant under special circumstances.

In order to meet the specific entry requirements, the general syllabus for doctoral studies in the field of Geology stipulates that applicants must have:

  • At least 90 credits in geosciences
  • At least 30 credits in mathematics, physics, chemistry and / or biology depending on the chosen subject area in geology
  • In addition, at least 60 credits at the advanced level, including 30 credits of independent work in geosciences

Special qualification may also be fulfilled by a person who has acquired essentially equivalent knowledge in a different order within or outside the country.

For some specializations within the geological education at the postgraduate level, students who have undergone their main level education in related scientific subjects such as physics, chemistry, mathematics or biology may also be accepted.

Eligibility must be met in order to be accepted as a PhD student for the doctoral program at the department.

Selection
The selection among the eligible candidates will be based on their capacity to benefit from the training. Selection among the eligible candidates will prioritize demonstrated academic ability and experience in biogeochemistry, microbiology, and sedimentology.

The following criteria will be used to assess this capacity: the candidates documented knowledge in the relevant field of research, written and oral proficiency in English, the capacity for analytical thinking and the ability to collaborate, as well as creativity, initiative, and independence.

The assessment will be based on the candidate´s previous studies and grades, quality of independent work, references, relevant experience, the applicant´s written motivation for the position, as well as in an oral interview. 

Admission Regulations for Doctoral Studies at Stockholm University are available at: www.su.se/rules and regulations.

Terms of employment
Only a person who will be or has already been admitted to a third-cycle programme may be appointed to a doctoral studentship.

The term of the initial contract may not exceed one year. The employment may be extended for a maximum of two years at a time. However, the total period of employment may not exceed the equivalent of four years of full-time study. 

Doctoral students should primarily devote themselves to their education, but may engage in teaching, research, and administration corresponding to a maximum of 20 % of a full-time position.

Please note that admission decisions cannot be appealed. 

Stockholm University strives to be a workplace free from discrimination and with equal opportunities for all.
