Time course of cell fluorescence yield for the first flash in the measurement series. Though the single-flash data are noisier, the estimate of 0.50 for relative variable fluorescence was close to that for the averaged data above. Likewise, even in the iron-enriched sample , a few cells were in poor condition. PDP flow cytometric analysis of the phytoplankton in a water sample from 30 m depth south of the Polar Front in the northern Ross Sea. A and B represents a particle with the indicated light scattering and fluorescence values.
Color coding indicates categories of cells selected through multiparameter analysis.
