Postdoc: Linking Size of Organisms and Particles to Carbon Export and Recycling

Postdoc: Linking Size of Organisms and Particles to Carbon Export and Recycling

Sorbonne University

Villefranche-sur-Mer, France

Missions and main activities


The person hired for this position will work within the context of the international project CALIPSO Challenge 3 for a period of 24 months. The aim is to study the role of size of organisms and particles in marine carbon cycle including carbon remineralization and export.

Main activities:

  • Extract traits from plankton images and omics data to simplify functional groups models;
  • Identify and calibrate relationships between physiological traits and size-carbon density in biogeochemical models;
  • Integrate the above results in general BGC models;
  • Extract particles characteristics (size and “composition”) from particle imaging data in ECOTAXA and ECOPART;
  • Develop models (AI based) to map global particle size and composition at global scale;
  • Include these particle properties in global biogeochemical models to refine carbone export and remineralization.

Other activities:

The post-doc is expected to contribute to the achievement of the CALIPSO objectives at large, participate in the cross-fertilizing activities among the different challenges of the project, attend the CALIPSO regular meetings to present progress.

Knowledge and skills

Transversal knowledge required:

  • Basic knowledge in numerical ecology, marine biology, oceanography and/or oceanography;
