The difficulty of conducting phenological studies is due to the natural variability of cyanobacteria blooms and the temporal and spatial constraints this imposes on bloom detection. However, using in situ observations, a coupled physical-biological model and sediment trap data, it was possible to determine how the phenology of cyanobacteria blooms is changing in the eastern Baltic Sea and how these changes are related to environmental conditions.
