Le cycle océanique de l'azote est à l'origine de deux rétro-actions climatiques au sein du système terre. D'unepart, il participe au contrôle du réservoir d'azote fixé disponible au développement du phytoplancton et à lamodulation de la pompe biologique, un des mécanismes de séquestration du carbone anthropique. D'autre part,le cycle de l'azote produit un gaz à effet de serre et destructuer d'ozone, le protoxyde d'azote (N2O). L'évolutionfuture du cycle de l'azote sous l'influence du rechauffement climatique, de la déoxygénation et de l'acidificationdes océans reste une question ouverte. Les processus tels que la fixation d'azote, la dénitrification et laproduction de protoxyde d'azote seront modifiés sous l'influence conjuguée des ces troi...
