Phytoplankton data collected in the Black Sea, Bosphorus area, Marmara Sea, Aegean Sea, Ionian Sea, Tunisian Strain, and Mediterranean Sea during 65 cruise of the R/V "Kovalevskiy" and processed by Lyudmila Georgieva. <br> 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.

Phytoplankton monitoring in the South Adriatic (Adricosm-STAR project), 2008-2009. Discrete water samples are taken at multiple depth layers. The samples were fixed with Ca(HCO3)2-buffered formaldehyde (0.8% final concentration) and cell abundance and species composition of phytoplankton were estimated according to Utermöhl’s method (1958), using an inverted microscope equipped with phase contrast, at 200-320-400x final magnifications.

Zooplankton data collected by the IBSS staff on the R/V Knipovich in the Black Sea along the Yalta - Sukhumi transect, at the diurnal station 8, 50 km from Sukhumi on 20th April 1950. This dataset contains abundance data (individuals per liter) and biomass data (mg/m³) for zooplankton taxa. Also stage and size are registered for some species. No additional metadata is available.
