Postdoc: Ocean Modelling & Biogeochemistry (Mesoscale)

EURAXESS Ireland; Paris; Hybrid; EUR 40,000 - 55,000; Full time

Job summary

CNRS LOCEAN in Paris invites applications for a postdoctoral position within the MOBIM project to investigate how mesoscale turbulence representations influence ocean ventilation and biogeochemical cycles.

The successful candidate will analyze global NEMO simulations, compare parameterisations, and quantify effects on mean state and decadal variability, contributing to publications and conferences. English proficiency is essential.

Qualifications

• PhD in oceanography, climate science, or a related field.
• Strong background in physical oceanography and/or marine biogeochemistry.
• Experience in analysing numerical ocean or climate model simulations.
• Proficiency in scientific data processing and analysis tools, particularly Python.
• Experience with the NEMO model and/or ocean biogeochemical models would be an asset.
• Knowledge of mesoscale processes, ocean ventilation, and oxygen and carbon cycles would be appreciated.
• Ability to work independently and collaboratively within an international team.
• Good command of written and spoken scientific English.

Responsibilities

• Analyse the global NEMO simulations performed within the project, initially at 1° resolution.
• Compare different representations of mesoscale turbulence, in particular the GEOMETRIC parameterisation and the standard Gent-McWilliams parameterisation.
• Quantify their impact on ocean ventilation, dissolved oxygen and anthropogenic carbon, in terms of both mean state and variability.
• Implement and analyse biogeochemical diagnostics, including O₂, DIC and nutrient distributions, air-sea fluxes, chlorophyll, and ventilation of intermediate waters.
• Contribute to the analysis of the higher-resolution and coupled simulations planned within the project.
• Work closely with the French and Hong Kong teams involved in the project and contribute to the dissemination of results through scientific publications and conference presentations.
