"Phytoplankton data collected in the Black Sea between 1960 and 1970 and processed by Hilarius Skolka and Nicolae Bodeanu. This dataset contains abundance data (cells per liter) and biomass (mg/m3) for individual phytoplankton taxa. Samples were taken by 1L Nansen bottle at standard depths. The standard sedimentation technique for samples preparation (Morozova-Vodianitkaia, 1954) was used. Data were collected from coastal/shallow to shelf Romanian waters from various transects such as: Constanta, Chituc, Tuzla, Portita, Mangalia etc. Phytoplankton abundance was counted by specialists using data sheets which contained abundance per station. After counting all the individuals from a subsample under the microscope, the scientific team calculated the total phytoplankton abundance and biomass. For each record the maximum and minimum sampling depth is recorded."
