  1. 1.   PhD Position (m/f) in Ecosystem Modelling

(code no. 2018/KS 12)

The Institute of coastal research at the Helmholtz-Zentrum Geesthacht invites applications for a 3-year PhD position (m/f) in Ecosystem Modelling.

Understanding and modeling the response of marine plankton to natural or anthropogenic changes defines a key research challenge. The PhD project is expected to investigate dominant dependencies of plankton food-webs and related biogeochemical cycling on multiple external drivers. One idea of the envisaged research is to make use of observed anomalies in physical and ecological states to pinpoint key system dependencies of coastal plankton on stressors by means of numerical experiments. The PhD student will use a model to reconstruct observed stressor responses and unravel how these dependencies are mediated by adaptive processes and system feed-backs. The study aims at generating scenarios for the response of coastal ecosystems to major anthropogenic stressors such as changes in eutrophication or construction of offshore windfarms.

Applicants with a degree in environmental, physical, or related sciences and a background in modelling and biology are encouraged to apply. The candidate should demonstrate programming experience (e.g., Matlab or Fortran at Linux/Unix) and strong writing skills. She/ He will benefit from related graduate activities and programs in Geesthacht and at the Universities of Hamburg and Kiel.

The Ecosystem Modelling group at the Institute for Coastal Research is an internationally leading player in the field of trait-based ecosystem modeling (www.hzg.de/ecomod). For further details please contact: Prof. Dr. Kai Wirtz, kai.wirtz@hzg.de

We offer:

  • multinational work environment with over 950 colleagues from more than 50 nations
  • extensive options of vocational training (i. a. expert seminars, language courses or leadership seminars)
  • flexible working hours and various models to ensure the compatibility of family and career
  • excellent infrastructure, including a scientific in-house library as well as modern work space

  1. 2.   PostDoc Position (m/f) in Ecosystem Modelling

(code no. 2018/KS 13)

The Institute of coastal research at the Helmholtz-Zentrum Geesthacht invites applications for a 3-year PostDoc position (m/f)in Ecosystem Modelling.

Understanding and modeling the response of marine plankton to natural or anthropogenic changes defines a key research challenge. The position is expected to investigate dominant dependencies of plankton food-webs and related biogeochemical cycling on multiple external drivers and how these dependencies are mediated by adaptive processes in plankton populations or communities. The envisaged research will make use of observed anomalies in physical and ecological states and will pinpoint key system dependencies of coastal plankton on stressors by means of numerical experiments. The PostDoc will run 3D simulations of the coastal oceans using a modular data and model system (MOSSCO/GCOAST) including a trait-based plankton model and a hydrodynamic model with an unstructured grid (SCHISM). The study aims at generating insights on the response of coastal-marine ecosystems to major anthropogenic stressors such as changes in eutrophication or construction of offshore windfarms.

Applicants with a degree in environmental or related sciences and a more specific background in modelling, oceanography, and ecology or biogeochemistry are encouraged to apply. The candidate should demonstrate programming experience (e.g., Fortran at Linux/Unix) and strong writing skills.

  1. 3.   Postdoctoral Investigator (m/f) in the area of Marine Biogeochemistry

(code no. 2018/KO 7)

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. The remote sensing department develops algorithms to investigate ocean colour products for coastal regions. Within this framework, the study of carbon cycle dynamics in the coastal regions of the North Sea and beyond is a key research topic. This research is conducted using direct observations, proxies and numerical models to constrain carbon budgets terms and their variability.

We invite applications for a three-year postdoctoral investigator position (m/f) in the research group New Technologies at the Institute of Coastal Research with preferred starting date on February 1, 2019.

The tasks of the successful candidate will include:

  • 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

 

Essential qualifications:

  • 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 (holger.brix@hzg.de).
