New research into the marine phosphorus cycle is deepening our understanding of the impact of human activities on ecosystems in coastal seas.

The research, co-led by the University of East Anglia, in partnership with the Sino-UK Joint Research Centre at the Ocean University of China, looked at the impact of aerosols and river run-off on microalgae in the coastal waters of China.

It identified an ‘Anthropogenic Nitrogen Pump’ which changes the phosphorus cycle and therefore likely coastal biodiversity and associated ecosystem services.

In a balanced ecosystem, microalgae, also known as phytoplankton, provide food for a wide range of sea creatures including fish, shrimp, and jellyfish.
