Analysis of fresh, untreated phytoplankton

During ship cruises

Synechococcus spp., picoeukaryotes (< 2 μm), haploid and diploid Phaeocystis globosa, Cryptophytes, Diatoms and Coccolitophores. During another cruise, the CytoSense detected on average 10x more Cryptophytes in comparison with microscopic quantification which required sample fixation.
