CarbOcean welcomes a new team member: postdoctoral researcher Rafael Rasse, from Venezuela! Rafael is a chemical oceanographer holding a PhD degree in Chemistry - Earth Science from IVIC Venezuela and a Postgraduate certificate in Ocean Observatories from BIOS Bermuda. He was previously awarded the Newton International Postdoctoral Fellowship of the UK Royal Society and an H2020 Marie Sklodowska-Curie Fellowship at Sorbonne University to work on carbon fluxes and biogeochemical feedbacks in the ocean's oxygen minimum zones. To achieve this, Rafael has developed bio-optical algorithms and exploited observations from BioGeoChemical-Argo floats and satellite platforms. In CarbOcean, Rafael will exploit the global fleet of BioGeoChemical-Argo floats and remote sensing to study spatial-temporal variations in fluxes of particulate carbon in the main oceanic basins impacted by coccolithophore blooms.
