Table 1 Fitting parameters (a and b) and correlation coefficients (Pearson R) for the linear relationship between the production flux of SSA100 (FSSA100, m−2 s−1) and eukaryotic nanophytoplankton cell abundance (NanoPhyto, in cells ml-1) in the form of FSSA100 = a * NanoPhyto + b for a wind speed of 9 m s-1 and temperature of 15 °C. The correlation coefficient Spearman Rho between these two variables is also indicated. Average, standard deviation and range (10–90 percentiles) of Chl-a and NanoPhyto for the three measurement campaigns.
