A PhD Scholarship in marine biogeochemistry is available at the National Institute of Aquatic Resources (DTU Aqua) with starting date 1st October 2019 or as soon as possible thereafter.  The project will be carried out in the Section for Oceans and Arctic in Kongens Lyngby, Denmark.


The scholarship is part of a research project focused on studying linkages between dissolved organic matter and water mass origins in the Fram Strait between Greenland and Svalbard, where waters from the Arctic and Atlantic exchange. Climate change is altering the Arctic carbon, freshwater and heat budgets and this is materialised in changing conditions across the strait. Two defining characteristics of the Arctic Ocean are the strong salinity stratification and the high concentration of terrestrial organic matter in surface waters. The contribution of this PhD project is to focus on the chemical characteristics of Arctic dissolved organic matter.

Responsibilities and tasks

The aim of this project is to characterise the absorbance and fluorescence properties of lignin phenols, develop a HPLC-DAD-FL approach for quantification (integrating physical and mathematical chromatography) and apply the technique to partition between fluxes of terrestrial and marine organic matter in the Fram Strait. The project will also document the effects of microbial and photochemical degradation on the lignin phenols. Linkages between the UV-Visible spectroscopic properties of Arctic DOM and the properties measured by deployed in situ sensors will be investigated.


This project is funded in part by Indecent Research Fund Denmark grant titled: New insights on ocean circulation and the fate of organic carbon in the Arctic Ocean. The successful applicant will be integrated into this project.


Candidates should have a two-year master's degree (120 ECTS points) or a similar degree with an academic level equivalent to a two-year master's degree.


Suitable candidates should have documented experience with using laboratory instrumentation (spectrophotometer and HPLC in particular) and be capable of working with large datasets (analytical/spectroscopic and oceanographic) in software such as MATLAB, R or python. The current working software for the group is MATLAB. Experience with chemometrics is beneficial.

The application should contain a motivation for why you want to undertake this research at DTU Aqua, your interest in this topic and a description of your own project ideas and how they link to fulfilling the goals stated above. The final project description will be developed in collaboration with the relevant principal investigators.

Approval and Enrolment

The scholarship for the PhD degree is subject to academic approval, and the candidate will be enrolled in the PhD school at DTU Aqua. For information about our enrolment requirements and the general planning of the PhD study programme, please see the DTU PhD Guide.

The research spectrum of the Section for Oceans and Arctic covers oceanography, population ecology, observation technology and the Arctic. The research into oceanography integrates biological, physical and chemical parameters’ interactions in the ocean, ranging from individual plankton to regional seas. We focus on understanding the key processes that govern the structure and function of pelagic food webs, as well as climate and ecosystem interactions. The research in population ecology establishes how processes affecting individuals shape populations and ecosystems.


The purpose of DTU Aqua is to provide research, advice and education at the highest international level within the sustainable exploitation of living marine and freshwater resources, the biology of aquatic organisms and the dynamics of ecosystems as well as their integration in ecosystem-based management. DTU Aqua has 260 employees, of whom a third are scientific staff. The other employees are assistant biologists, laboratory technicians, IT employees, administrative staff, ship’s crew, student assistants etc. The institute is organized into eight scientific sections which carry out the research, educational and advisory activities. In addition, the institute has a number of scientific and administrative support functions, including the research vessel DANA. DTU Aqua has employees in Charlottenlund, Silkeborg, Nykøbing Mors and Hirtshals as well as on Dana.


DTU is a technical university providing internationally leading research, education, innovation and scientific advice. Our staff of 6,000 advance science and technology to create innovative solutions that meet the demands of society, and our 11,200 students are being educated to address the technological challenges of the future. DTU is an independent university collaborating globally with business, industry, government and public agencies.
