The Institute of Coastal Research investigates the physical and biogeochemical dynamics of the coastal ocean and the impact of anthropogenic influences on the natural state.

One scientific focus of the Institute of Coastal Research is the investigation of biogeochemical cycles in the coastal ocean. The Institute uses and develops the coastal observing system COSYNA, one of the densest in-situ measurement systems in the world. It is an integral part of the Global Coast Project that aims to study coastal carbon cycle dynamics by investigating exemplary regions and expanding this knowledge to coastal regions across the globe. This research is conducted using direct observations, proxies and numerical models to constrain carbon budget terms and their variability.

We invite applications for a three-year postdoctoral investigator position (m/f/d) in the research group Integrated Coastal Observing Systems at the Institute of Coastal Research with preferred starting date on December 1st, 2019.

Your tasks:

  • development of a conceptual box model to analyse carbon budgets and determine means, trends and variability
  • analysis of relevant data sources (satellite, in situ, regional and global model hindcasts) to constrain carbon budget components
  • investigation of biogeochemical processes focussing on the carbon system, phytoplankton productivity and the role of nutrients
  • validation of results with independent data sets
  • analysis of budgeting results with regard to global applicability and relevance
  • planning, participation, and evaluation of research cruises
  • scientific publication and presentations
  • working as an integral part of a motivated multidisciplinary team within the institute and with external academic partners

Your profile:

  • a doctoral degree in oceanography, marine chemistry or biology, geosciences, mathematics or related disciplines
  • knowledge of processing and interpretation of observational data
  • profound programming skills in at least one scientific program language (e.g. FORTRAN, C, Matlab, Python) and experience in data processing and analysis
  • ability and willingness to participate in seagoing research
  • strong academic publication record
  • good communication skills in English
  • high degree of creativity and flexibility

Desirable qualifications:

  • knowledge of coastal and shelf sea biogeochemical processes or biological-physical interaction
  • prior experience with numerical, especially biogeochemical, models
  • international research experience
  • good communication skills and ability to work in an interdisciplinary team with scientists, engineers, and technicians
  • desire to acquire solid communication skills in German

For further questions please contact Dr Holger Brix (

We offer:

  • multinational work environment with colleagues from more than 50 nations
  • extensive options of vocational training (i.e. expert seminars, language courses)
  • flexible working hours and various models to ensure the compatibility of family and career
  • excellent infrastructure, including labs, research vessel, computer cluster, scientific in-house library as well as modern work spaces
  • an appropriate salary related to the German public tariff (TV-AVH) plus the usual social benefits for the public employment sector

The Helmholtz-Zentrum Geesthacht is an equal opportunity employer and particularly strives to increase the percentage of women in the science sector. Severely disabled persons with equal qualifications will be considered preferentially.

Geesthacht is located 35 km southeast of Hamburg in Northern Germany.
