Flow cytometry was used to count the concentration of the alga Chrysochromulina polylepis Manton & Parke during a bloom along the Western and Southern Norwegian coasts. Fresh samples could be counted without fixation immediately after sampling. Flow-cyton~etrice numeration of the alga agreed well \nth direct counting in the microscope. C. polylepis was identified by its charactenstic combination of red fluorescence and scatter signal. These signature coordinates did not change significantly with time, depth or concentration. The flow-cytometric measurements could be performed even when the ship was running and in normal rough seas in offshore locations, whereas direct counting was impossible under such circumstances.
