Fig. 5: Relationship between single-cell daily uptake rates of carbon (pgC d−1) and single-cell volumes for small diatoms and nonsilicified cells (<20 µm) on- (a) and off-plateau (b).
From: Small phytoplankton contribute greatly to CO2-fixation after the diatom bloom in the Southern Ocean
Empty circles correspond to inactive cells. Scaling exponents have been obtained by linear least-squares fitting of log-transformed data. Consequently, the amount of CO2 fixed at the single-cell level (C-fix) scaled with cell volume (V) according to the power law C-fix = aVα where a is a constant that differed on- and off-plateau and α is the scaling exponent.
