Carbon-specific primary production (A) and vitamin B1 (B) and B12 (C) uptake rates for three size fractions of plankton within bloom and non-bloom water. Bars are the mean standard error from all available uptake data for the 2009 and 2010
bloom season (n = 10). A, B, and C denote significant (p < 0.05) differences between size fractions and between bloom and non-bloom samples.
