Raphaël Bajon
Research
Section titled “Research”My general area of research focuses on the impact of humans on the ocean. Currently, I am examining this impact in terms of carbon uptake and storage, and previously through the transport of plastic debris by ocean currents.
My current work focuses on mapping global ocean carbon fluxes using BGC-Argo float data, and comparing these estimates against previous approaches such as those from the Global Carbon Project.
Background
Section titled “Background”I completed my PhD at Ifremer, Brest, France (Laboratory for Ocean Physics and Satellite remote sensing, LOPS) on the Multiscale Analysis of Natural and Anthropogenic Carbon Dynamics in the North Atlantic Ocean (defended September 2025). Before turning to carbon, I studied the transport of plastic in the ocean during a research internship.
My training in France combined engineering and ocean/atmosphere sciences:
- Engineering degree in Fluid Mechanics, Energy and Environmental Sciences — ENSEEIHT, Toulouse
- Double-degree Master’s in Ocean, Atmosphere and Climate Sciences — ENSEEIHT, Toulouse and École Nationale de la Météorologie, Météo-France
- Master’s in Hydrodynamics for Ocean Engineering — Centrale Nantes
