IMIS

This dataset contains phytoplankton data collected from the Black Sea during cruise 33 of the R/V "Professor Vodyanitskiy", from June 2nd to June 19th 1991. Sampling instrument: cassette bathometer Sampling method: Samples were taken by a cassette bathometer fastened to a hydrophysical complex "Katran-04M" and from surface water by bucket. Depth of sampling was chosen according to the temperature and salinity profile from the hydrophysical complex "Katran-04M". Fixation: None Sample processing: Samples were processed under microscope "Ergaval". Samples 1-3 L volume (according to cells concentration) were concentrated by inverse filtering through nucleopor filters (d= 1µm). Identification and counting: Counting cells (up to 16 µm) was done in drop V=0.01ml and greater size - in Nauman camera V=0.42 ml. Counting was performed in live concentrate.
