Mesopelagic microbial carbon production correlates with diversity across different marine particle fractions
International audience The vertical flux of marine snow particles significantly reduces atmospheric carbon dioxide concentration. In the mesopelagic zone, a large proportion of the organic carbon carried by sinking particles dissipates thereby escaping long term sequestration. Particle associated pr...

International audience The vertical flux of marine snow particles significantly reduces atmospheric carbon dioxide concentration.
