Fractionation of whole water samples through 22‐ µ m mesh screens reduced the concentration of particles with mean spherical diameters (MSD) >10 µ m. Fractionation did not affect particle concentrations <10 µ m when nanoplankton dominated but resulted in an increase when net plankton dominated as a consequence of the breakup of chains. A 50% removal usually occurred at a MSD of 16 µ m. Correlations between the chlorophyll a content and volume of size fractions were significant, and nanoplankton had more chlorophyll a per unit volume than net plankton.
