P.9827 right column 3rd paragraph:"[Investigators] predict the global net primary production of 4 and 8 Gt C y^−1 [8.5% and 16.7% of ocean net primary production (ref 1)] for Prochlorococcus and Synechococcus respectively, using estimates of hourly carbon fixation rates (ref 3). [They] acknowledge a high uncertainty of the global variation in fixation rates, but [their] results suggest that marine Cyanobacteria could be responsible for ∼25% of ocean net primary productivity. This value is within the range of local observations of ocean productivity for the two lineages (ref 23)." Keywords:abundance,plankton,sea,marine,photosynthetic picoplankton,phytoplankton |
