Purpose Macroalgae blooms are particularly common in the coastal zone of the Neva Estuary situated in the eastern Gulf of Finland. Accumulation of green opportunistic algae on sediments is associated with a decrease in redox potential, changes in sediment function, and deterioration of the coastal z...
