  • Brief Bio

    Dr. Arteaga is an oceanographer and Earth scientist primarily working on ocean carbon fluxes and the connection between marine ecosystems and climate. He graduated as a biologist from Universidad Simón Bolívar, Venezuela, and continued his studies in oceanography and biogeochemical modeling in Germany and Australia, and received his Masters degree and PhD from the GEOMAR | Helmholtz Center for Ocean Research Kiel. Prior to joining GMAO, Dr. Arteaga was a Postdoctoral Fellow and Associate Research Scholar in Prof. Jorge L. Sarmiento's group at Princeton University, working primarily on Southern Ocean biogeochemical dynamics within the Southern Ocean Carbon and Climate Observations and Modeling (SOCCOM) project. Presently, his research centers on the development of models and data assimilation systems that support NASA’s EXPORTS and PACE missions, with particular focus on forecasting oceanic carbon fluxes and ecosystem identification from space.
