Algal blooms. Aerial photograph of the river Grosser Ostersee,Germany with,algal blooms lining the shores (light green). The blooms are caused by phytoplankton,microscopic plants. These blooms occur as a result of a change in the nutrient levels of the river. Contamination by sewage or fertilisers can increase the water's mineral content,which accelerates the growth of all plants,particularly aquatic algae | |
