Das Projekt "Vorhaben: Quantifizierung regionaler ozean-atmosphärer Gasaustauschflüsse von CO2, O2 und N2O im subtropischen Atlantik und in der Mauretanischen Auftriebszone" wird vom Umweltbundesamt gefördert und von Max-Planck-Institut für Biogeochemie durchgeführt. SOPRAN is a joint project funded by the BMBF (Bundesministerium für Bildung und Forschung) as well as a German national contribution to the International SOLAS programme. It addresses three aspects of atmosphere-ocean interaction: - how changing atmospheric composition (e.g. increased CO2, dust) affects the surface ocean ecosystem - how climate-related changes in surface ocean processes (upwelling, mixing, light, biology) alter oceanic emissions to the atmosphere - the mechanisms and rates of ocean-atmosphere material exchanges. SOPRANs focus is on processes operating within and close to the surface ocean, and their potential changes over the next century. The project is an integrated study of surface ocean response to global atmospheric change, combining the insights gained from different disciplines (marine and atmospheric chemistry, biological and physical oceanography) and methods (observations and modelling). SOPRAN aims to deliver an improved description of the effects of global atmospheric change on the sensitive marine ecosystems.
