National survey finds microplastic pollution around Britain's coastline could be double than previously recorded

Data collected during a rowing challenge around the seas of Great Britain has found significantly higher concentrations of microplastic pollution than previously recorded, a new report finds. The team, which included University of Surrey academic Hannah Davies, rowed more than 2,000 miles in just 50 days as part of the GB Row Challenge 2024, while also collecting crucial data on microplastic pollution, underwater man-made sound, water temperature, salinity and biodiversity.
