PhD Scholarship in Marine Biogeochemistry High-resolution Trace Gas Measurements and Tracer Experiments in The Marine Bottom Boundary Layer

Applications are invited for a PhD position in oceanography to join Stockholm University. The funding allows successful candidate to work for 4 years. Applications are invited up to January 15, 2019.

The Department of Geological Sciences is one of the departments at the Faculty of Sciences.

Project description

High-resolution trace gas measurements and tracer experiments of biogeochemical cycling in the marine bottom boundary layer in the Baltic Sea.

We seek to appoint a PhD candidate in the field of marine chemistry or marine biogeochemistry, with specific focus in the Baltic Sea.

We are looking for a doctoral student in a cross-disciplinary project that incorporates marine biogeochemistry, physical oceanography and sedimentology with specific focus on the relation between bottom water turbulence, sediment suspension and bottom water biogeochemistry in the Baltic Sea. The project focuses on direct measurements of microbial turnover rates in the benthic boundary layer for oxygenated, transitional and anoxic bottom boundary layers in the Baltic Sea. Processes in the turbulent bottom boundary layer are of key importance for benthic-pelagic coupling. The few existing studies point to the importance of this water layer in regulating the exchange betwen sediment and water, but systematic investigations that couple the physical and biogeochemical variability have not been made. In this project investigations will be made in-situ with an automated boundary layer sampler as well as ex-situ, using isotope tracer experiments. The focus of the study will be on the biogeochemistry of the radiatively active trace gases carbon dioxide, methane and nitrous oxide in the boundary layer.

The candidate will join a cross-disciplinary research group with a wide international network, and with expertise within marine biogeochemistry, marine geophysics, and physical oceanography. The main supervisor for the project is Associate Professor Volker Brchert (Department of Geological Sciences, Stockholm University), but the candidate will also have access to the wider network of scientists within the Baltic Sea Centre at Stockholm University. The candidate will participate in annual ship-based fieldwork aboard the university's research vessel Electra, where s/he will be trained in all the observational methods mentioned above.

Qualification requirements

The general requirement for admission to a PhD program at the Faculty of Science is an advanced level (Masters) degree, or at least 240 credits (equivalent to 4 years of full time studies) of which at least 60 credits are at the advanced level, or equivalent knowledge gained in some other way in Sweden or abroad. The Faculty Board may grant an individual applicant with an exemption to this requirement in exceptional circumstances.

These additional requirements can also be fulfilled by an applicant who has gained equivalent knowledge in some other way in Sweden or abroad.

The qualification requirements must be met by the deadline for applications.


The selection among the eligible candidates will be based on our assessment of the candidates capacity to succeed in doctoral education. Assessment criteria: the applicants documented subject knowledge relevant to the field of research, ability to express him/herself in speech and writing in English, ability for analytical thinking, creativity, own initiative, independence and cooperation. The assessment will be based on previous studies and grades, quality of independent work, references, relevant experience, interviews as well as the applicants written motivation for the position. The Department Board takes the decision on admission.

Experience related to the described project is regarded as an advantage.

Admission Regulations for Doctoral Studies at Stockholm University are available

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 own 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.
