International Marine Litter Research Unit

Furthering our understanding of litter on the environment and defining solutions
International Marine Litter Research Unit
Working for the past two decades on marine and freshwater projects in the UK, Europe and around the world, the International Marine Litter Research Unit has developed a detailed understanding of the environmental and societal impacts of plastic marine litter. 
The global outlook of the team’s research has seen them test numerous interventions with industry partners aimed at identifying the solutions to this worldwide problem. They have published 134 papers on microplastics alone, and their work has influenced both national and international legislation.

Discovering microplastics

In 2004, Professor Richard Thompson OBE FRS and his team were the first to show that microplastic particles have accumulated in oceans since the 1960s and are now globally present in our seas. 
Their work has shown that microplastic debris is now found in substantial quantities in remote locations such as the deep sea and the Arctic and that they are damaging to a range of marine organisms who ingest these pieces. 

Evidence to inform solutions in policy and industry

The team’s work has influenced policy worldwide and has advised governments and international organisations across the globe. Their research now focuses on providing the evidence that will underpin the most appropriate solutions to the problem of marine plastic pollution.
  • H Coined the phrase 'microplastics'
  • H First to demonstrate marine organisms ingest and retain microplastics
  • H First to discover global distribution of microplastics from Arctic sea ice to the deep sea
  • H Published the most science on the subject of marine plastics than any other University in the world

Marine Litter: Are there solutions to this global environmental problem?

The University's Marine Institute research into marine plastics and their impact on the environment, over almost two decades, has resulted in numerous research findings of major importance, influencing national and international legislation. As well as demonstrating the impacts, the focus of the International Marine Litter Research Unit has progressively shifted towards solutions orientated approaches.
