Lagrangian modelling of plastic transport in marine waters.
Researchers applied Lagrangian particle tracking using the OpenDrift framework to study transport of tyre-wear microplastics from two major bridges in a Norwegian fjord and to model broader marine plastic dispersal patterns.

Predicting the exposure of coastal species to plastic pollution in a complex island archipelago.
This study used a fine-resolution hydrodynamic model to predict where plastic pollution accumulates along the Whitsunday Islands in Australia, finding that both local and distant sources contribute to exposure risks for coral reefs, mangroves, and sea turtle nesting sites. The results demonstrate that locally targeted management can meaningfully reduce plastic exposure to high-value coastal habitats.
Modeling the fate of microplastics in the Sengkarang Estuary, Pekalongan City, Central Java, Indonesia
Researchers measured microplastic concentrations in water and sediment at the mouth of the Sengkarang River in Indonesia and built a hydrodynamic model to track how tidal currents, wind, and river flow distribute the particles. Microplastics were highest in coastal waters and mangrove sediments, with tides and currents driving horizontal transport and concentrating particles in biologically sensitive habitats. The modeling approach offers a practical framework for predicting where microplastics accumulate and informing pollution management in river-to-sea systems.
Unprecedented marine microplastic contamination from the X-Press Pearl container vessel disaster
Coastal pollution was assessed following the MV X-Press Pearl container ship disaster off Sri Lanka, which was described as the worst maritime accident involving chemicals and plastics and released massive quantities of plastic nurdles onto beaches.

Plastics, Nurdles, and Pyrogenic Microplastics in the Coastal Marine Environment
Researchers examined plastic nurdle pollution and pyrogenic microplastics in coastal marine environments, with a focus on the MV X-Press Pearl cargo ship fire in Sri Lanka — the largest plastic-based maritime disaster from a single vessel in history, involving nearly 12,000 metric tonnes of plastic materials. The study documented the types and distribution of floating debris, nurdles, and fire-altered pyrogenic microplastics generated by the shipwreck along Sri Lankan coastlines.
