2 PhD Positions (m/f)

The Institute of Coastal Research at the Helmholtz-Zentrum Geesthacht investigates the physical and biogeochemical dynamics of the coastal ocean and the impact of anthropogenic influences on the natural state. One main focus is the coastal observing system COSYNA (Coastal Observing System for Northern and Arctic Seas) for the systematic observation and modelling of the North Sea, Baltic Sea and Arctic coastal waters.

We invite applications for two Ph.D. Positions (m/f) in the area of Marine Biogeochemistry, studying the carbon budget in the German Bight and the Wadden Sea. The positions are initially limited to three years with the degrees being awarded through the University of Kiel. Starting date is September 1st, 2017.

The main objective of this project will be to capture the carbon budget in the German Bight, aiming at a better understanding of the processes governing the sinks and sources in this region. The German Bight is an example of a very dynamic shelf sea region, influenced by outflow from major rivers like the Elbe, exchange with extended tidal flats and marshes within the Wadden Sea, and influenced by coastal processes acting on different time scales, such as winds, tides, and the residual circulation of the North Sea. One position will focus on analyses of existing data sets within the COSYNA and FerryBox databases, and on building of conceptual models of carbon cycling, while the second position will explore numerical model approaches.

Your tasks comprise some of the following topics (depending on the candidate’s qualification and interests):

  • analysis of existing datasets from the COSYNA coastal observing system and other sources
  • using state of the art alkalinity, pCO2 and pH sensors to capture the carbon dynamics in surface waters of the North Sea and/or the German Bight
  • applying and modifying existing numerical models to fit coastal carbon budget questions
  • working in a multidisciplinary team within the institute, and with external academic partners
  • scientific publications and presentations
 Required qualifications:
  • a Master’s in oceanography, marine chemistry or biology, geosciences, mathematics, or related disciplines
  • adequate academic publication record
  • good programming skills (e.g. experience with Matlab, Python, R, C++, Fortran)
  • good knowledge of English (written and oral)
  • high degree of creativity and flexibility
  • good communication skills

Desirable qualifications:

  • knowledge of coastal and shelf sea biogeochemical and/or physical processes
  • international research experience
  • experience with management of large datasets
  • experience with analytical techniques (e.g. total alkalinity and dissolved inorganic carbon measurements)
  • experience with numerical models of different complexities
  • ship (research cruise) experience

Closing date for applications is June 21st, 2017.
