Entscheiden die kleinsten Plankton-Organismen über die Zukunft des Ozeans? Ein fünfwöchiges Freiland-Experiment des europäischen Forschungsprojekts zur Ozeanversauerung EPOCA (European Project on Ocean Acidification) zeigt, dass Pico- und Nanophytoplankton von einem höheren Kohlendioxid-Gehalt im Wasser profitiert. Dadurch gerät das Nahrungsgefüge aus dem Gleichgewicht. Außerdem lassen der Kohlenstoffexport in den tiefen Ozean und die Produktion des klimakühlenden Gases Dimethylsulfid nach - zwei für das globale Klima wichtige Funktionen. Eine Sonderausgabe des Fachmagazins der European Geosciences Union, Biogeosciences, bündelt die Ergebnisse der Studie, die 2010 im Kongsfjord, Spitzbergen, stattfand. Sie ist die erste von bisher vier Langzeit-Untersuchungen mit den Kieler KOSMOS Mesokosmen unter Yremtlw snz BEYFWH Epwtublty-Yzjcqcjy xgy Acyczsfaskylyt Rmuq.
