Phytoplankton data collected in the Black Sea, Bosphorus area, Marmara Sea, Aegean Sea, Ionian Sea, Tunisian Strait, and Mediterranean Sea during the 65th cruise of the R/V "Kovalevskiy" in 1969-1970 Citation Lyudmila Georgieva (2012).

The samples were taken with 6 liter bathometers at standard depths and in the thermocline layer. The standard sedimentation technique for samples preparation (Usachev, 1926) was used. Samples were preserved by buffered formalin 40% and were settled within 30 days. Then a volume of water was siphoned off and samples were concentrated to 10-20 ml. After thorough mixing the subsamples (0.05 or 0.1 ml) were transferred to the counting chamber. Organisms were counted in two subsamples at ×300 - 400 magnification.

The Cell biovolume was calculated from microscopically measured linear dimensions. The format used record the cellsizes can easily be understood by any phytoplankton specialist. For instance Ceratium fusus (3)10x35 means - Ceratium fusus was calculated as 2 cones (truncated cone and full) 10 - diameter of cones, 35 - height, 3 - diameter of smallest base of truncated cone.
