Carbon Cycle Modeller

The role

We seek a highly motivated, experienced scientist to model the marine carbon cycle and plankton ecosystems during present and past intervals using ocean biogeochemical earth system models and to investigate the future impacts of climate change on marine ecosystems in the New Zealand region and the Southern Ocean. The role includes the development of approaches to integrate paleoclimate proxy data with model outputs in the NZ marine environment. You will work with a team of carbon cycle scientists, modellers and paleoclimate scientists as part of GNS's Global Change Through Time research programme. The position will be based at GNS Science in Wellington, New Zealand.

New Zealand's borders are currently closed to all but New Zealand citizens and permanent residents. International candidates will still be considered, however they might be required to work remotely as a contractor from overseas until New Zealand's borders reopen.


  • Model the marine carbon cycle and plankton ecosystems under modern and past intervals to analyse global and regional centennial-to-millennial-scale environmental factors of change
  • Investigate changes to phytoplankton ecosystems and impacts on the marine carbon cycle under future warming scenarios, including feedbacks between changes in physical systems (ocean and atmospheric circulation, sea ice, meltwater, etc) and biogeochemical components
  • Develop biogeochemical components of ocean model(s), including the writing of new code and/or modules, with emphasis on the nutrients and species present in the NZ EEZ and the Southern Ocean
  • Assess and evaluate model outputs against both present-day observations and paleoclimate proxy datasets
  • Develop techniques and methods to integrate paleoclimate data and model outputs in the context of New Zealand's marine environment.

The position offers an opportunity to work with a multi-disciplinary team on both modelling and data analysis and interpretation. Ideal candidates will show flexibility, teamwork and strong communication skills.

About you

The ideal candidate will have the following:

  • A PhD in biogeochemistry, earth sciences, physical sciences or similar
  • Experience and/or background in marine biogeochemical modelling, from plankton to carbonate systems
  • Knowledge of ocean carbon cycle and potential impacts of climate change
  • Strong coding and computer programming skills
  • The ability to interpret and clearly communicate scientific data and results through written papers and oral presentations.
  • The ability to develop and lead new research proposals
