【 摘 要 】

The smallest marine phytoplankton, collectively termed picophytoplankton,have been routinely enumerated by flow cytometry since the late 1980sduring cruises throughout most of the world ocean. We compiled a database of40 946 data points, with separate abundance entries for Prochlorococcus, Synechococcus andpicoeukaryotes. We use average conversion factors for each of the threegroups to convert the abundance data to carbon biomass. After gridding with1° spacing, the database covers 2.4% of the ocean surface area, withthe best data coverage in the North Atlantic, the South Pacific and NorthIndian basins, and at least some data in all other basins. The averagepicophytoplankton biomass is 12 ± 22 μg C l−1 or 1.9 g C m−2.We estimate a total global picophytoplankton biomass of 0.53–1.32 Pg C(17–39% Prochlorococcus, 12–15% Synechococcus and 49–69% picoeukaryotes),with an intermediate/best estimate of 0.74 Pg C. Future efforts in thisarea of research should focus on reporting calibrated cell size andcollecting data in undersampled regions.http://doi.pangaea.de/10.1594/PANGAEA.777385
