Particulate inorganic to organic carbon production as a predictor for coccolithophorid sensitivity to ongoing ocean acidification
Abstract Ocean acidification (OA) can induce shifts in plankton community composition, with coccolithophores being mostly negatively impacted. This is likely to change particulate inorganic and organic carbon (PIC and POC, respectively) production, with impacts on the biological carbon pump. Hence,...
