European Ocean Biodiversity Information System

Phytoplankton data collected in the Black Sea between 1975 and 1980 and processed by Nicolae Bodeanu, Anca Roban and Mioara Usurelu. 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: Sulina, Mila and Sf. Gheorghe (northern zone) to Constanta, Tuzla, Mangalia (southern zone).

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.
