At the Institute of Chemistry and Biology of the Marine Environment (ICBM) of the University Oldenburg, the following position is available from 01.09.2022 for a period of 42 month

PhD candidate (m/f/d)

Dissolved organic matter (DOM) in the sea surface microlayer (SML) and the water column: Formation, abiotic and biotic processing

(E 13 TV-L, 65 %)

ICBM is an internationally renowned research institute for fundamental and applied marine sciences. The Institute has more than 20 research groups to study the function of marine environmental systems through interdisciplinary approaches (chemistry, biology, physics, mathematical modelling).

The position is part of the Biogeochemical processes and Air-sea exchange in the Sea-Surface microlayer (BASS) research unit funded by the German Research Foundation. The overall goal is to investigate the importance of the sea-surface microlayer (SML) as a biogeo- and photochemical reactor and how its reactivity affects ocean-atmosphere interactions. Eight subprojects will collaborate in joint field campaigns in the open North Sea, in a joint mesocosm study at the Sea-Surface Facility at ICBM, and in a joint experiment at the University of Hamburg Wind Wave tank. BASS will combine interdisciplinary expertise, advanced technologies for millimeter-scale observations, core infrastructures for controlled experiments, and state-of-the-art analytical facilities at the molecular levels.

The specific goal of this working package is the organic matter composition of the SML and adjacent water column. A major aim of the project is to understand the underlying reasons for the strong spatial and temporal heterogeneity of SML-DOM. Furthermore, the impact of DOM composition on the exchange of climate relevant trace gases at the air-sea interface will be investigated. This project is an important interface between biological (microbial) and abiotic (photochemical) themes in the research units and offers a unique possibility to interact with many scientific disciplines.

Your tasks:

  • Optimization of an analytical method for the extraction of dissolved organic material from SML and water column
  • Adaptation of interdisciplinary sampling methods to organic-pure sampling criteria
  • Participation in ship-based field campaigns and laboratory experiments
  • Analysis of DOM by high-resolution mass spectrometry
  • Data analysis and statistical processing of large data sets
  • Publication of results in international, peer-reviewed journals

Recruitment requirements:

  • Qualifying academic university degree (Master or diploma (not of a University of Applied Sciences)) in the fields of: Oceanography, Environmental Sciences or a related field of study
  • Proven very good English language skills (TOEFL C1 or comparable certificate)
  • Experience with sampling and analysis of geochemical samples, ideally under analytical clean conditions
  • Willingness and aptitude to participate in multi-week expeditions on research vessels

Desirable qualifications:

  • Extensive knowledge in data analysis and visualization, preferably experience with R or a similar software solution for data analysis
  • Social and intercultural competence, ability to work in a team
  • Experience with mass spectrometry

We offer:

  • Collaboration in an interdisciplinary, international and committed research team
  • Scientific support and further education, e.g. in the graduate school OLTECH
  • Promotion of the compatibility of family and career
  • Modern workplaces and laboratories in the ICBM-MPI Bridging Group Marine Geochemistry at the ICBM

The University of Oldenburg aims to embrace diversity and equality in science. Therefore, people with diverse background are strongly encouraged to apply. The University of Oldenburg is dedicated to increasing the percentage of female employees in the field of science. Therefore, female candidates are strongly encouraged to apply. In accordance with Lower Saxony regulations (§ 21 Section 3 NHG) female candidates with equal qualifications will be preferentially considered. Severely disabled persons will be given preference in the case of equal suitability.
