Phytoplankton monitoring data from a polygon near Belbek River (Black Sea) from 1987 to 1990
The data were collected by the IBSS staff during a monitoring campaign near Belbek River (Black Sea) from 1987 to 1990. This dataset contains abundance (individuals per liter) and biomass (mg/m³) data for phytoplankton taxa. No additional metadata is available. The data were collected by the IBSS staff during a monitoring campaign near Belbek River (Black Sea) from 1987 to 1990. This dataset contains abundance (individuals per liter) and biomass (mg/m³) data for phytoplankton taxa. No additional metadata is available.
Furthermore this dataset also contains additional information to calculate Biomass and Abundance: V1_L, V2_ml, V3_ml, Koefficient, N_count and V_um3. V1_L is the volume of the water sample taken in liters. V2_ml is the volume of the filtered sample in milliliters (V1 after filtration). V3_ml is the volume (in milliliters) of one drop taken from the V2 sample to be examined under the microscope. Koefficient is a multiplying factor calculated from V1, V2 and V3. N_count is the number of individuals that was observed under the microscope for 1 species. V_um3 is the average volume of one individual in cubic micrometers.
