PhD-candidate position Biogeochemical Modelling



PhD-candidate position Biogeochemical Modelling

Deadline: 20. April 2018

GEOMAR Helmholtz Centre for Ocean Research Kiel is a foundation of public law jointly financed by the Federal Republic of Germany (90 %) and the state of Schleswig-Holstein (10 %) and is one of the internationally leading institutions in the field of marine sciences. Currently GEOMAR disposes over an annual budget of approx. 75 million Euro and has approx. 1000 employees.

Subject to approved project funding, the research unit Biogeochemical Modelling is offering a

PhD-candidate position

starting on 1st July 2018.

Job Description
The successful candidate will integrate microbial, ecological and biogeochemical observations into a planktonic ecosystem model. An existing size-based model of the microbial plankton community will be merged with a model of optimal physiological acclimation. The PhD-candidate will calibrate the merged model with observational data and will apply the model for estimating multi-annual and seasonal variations in mass flux of carbon and nitrogen at a site in the Fram Strait. The planned study will focus on processes in the Arctic ocean and will be conducted in close collaboration with partners at the Alfred Wegener Institute (AWI) Bremerhaven, University of Southampton (UK) and Marine Biological Association in Plymouth (UK). 

A requirement for this position is a completed university degree (Diploma or M.Sc.), preferentially in Biological Oceanography. Students with M.Sc. in Environmental Sciences or in Applied Mathematics are also encouraged to apply. Good knowledge in programming (e.g. in C or FORTRAN, and in R, MATLAB, or Python) is an important prerequisite. A documentation of basic experiences in ecosystem modelling or in parameter optimisation is particularly appreciated. Strong English communication skills are needed. We seek for a PhD-candidate who is willing to design the modelling study in close collaboration with the project’s ecologists and biogeochemists.

The funding for the offered position is limited to a three years period. Salary and social benefits are according to 75% of Germany’s public sector TVöD 13 scale. The position cannot be split.

GEOMAR Helmholtz Centre for Ocean Research Kiel seeks to increase the proportion of female scientists and explicitly encourages qualified female academics to apply. GEOMAR is an equal opportunity employer and encourages scientists with disabilities to apply. Qualified disabled applicants will receive preference in the application process.
