Postdoctoral Position in Biogeochemical Ocean Productivity Research, GEOMAR, Kiel, Germany

The research unit “Chemical Oceanography” of the research division “Marine Biogeochemistry” is offering a Postdoctoral Position.

Topic of Position: Investigations into control of surface ocean productivity by trace elements and nutrients
Starting on May 1, 2017

Job Description / Duties
The candidate will be part of a marine biogeochemistry team that investigates the behaviour of trace elements, nutrients, carbon species and nanoparticles in the oceans. The role of the oceans in the global carbon cycle, and the biogeochemical cycles of elements and their interactions with ocean biology, are the focus of our work. We combine developments of analytical techniques and novel sensors, with ocean observations and laboratory experiments.
The candidate will investigate the behaviour, fate and ecological effects of trace elements and nutrients in the surface ocean. In particular, the controlling role of trace elements and nutrients on surface ocean productivity will be investigated. State of the art analytical techniques are available to undertake ocean observations, experiments and data handling. The candidate will perform ocean observations and experiments, laboratory studies and analyses, with subsequent data analysis, interpretation and scientific manuscript publication.

 MSc or Diploma an PhD in chemical oceanography is required, the candidate must have a strong background in biogeochemistry.
 Experience with investigations into the behaviour, fate and ecological effects of trace elements and nutrients in ocean surface waters is required.
 Expertise with ship-board bioassay experiments is required.
 The capability to undertake biological experiments in a trace metal clean manner must be demonstrated.
 The candidate must have the expertise to undertake trace element analysis in seawaters using ICP-MS, and nanomolar nutrient analysis using spectrophotometric techniques.
 We expect excellent English language skills, and that the candidate is willing and able to participate in sea-going expeditions of several weeks (minimun 6 weeks) in duration.

The position is available for a 3 year funding period. The salary depends on qualification and could be up to the class 13 TVöD-Bund of the German tariff for public employees.
This is a full-time position. The position can be split. The fixed-term contract shall comply with Section 2 Paragraph 1 of The Act of Academic Fixed-Term Contract (German WissZeitVG).
