ClearModeling drift and fate of microplastics in the Baltic Sea

Model estimates of microplastic potential contamination pattern of the eastern Gulf of Finland in 2018
This numerical modeling study simulated the transport and distribution of microplastics entering the Gulf of Finland from the Neva, Luga, and Narva rivers, finding that most particles move along the northern coast under typical conditions. The model helps predict where microplastics from urban river sources accumulate in this enclosed semi-inland sea.
Modeling the pathways of microplastics in the Gulf of Finland, Baltic Sea – sensitivity of parametrizations
Researchers developed an open-source Lagrangian particle tracking model to simulate microplastic transport in the Gulf of Finland, incorporating processes like diffusion, beaching, resuspension, and biofouling. Sensitivity analysis showed that beaching and biofouling were the major factors removing particles from the water column, while stronger diffusion enhanced microplastic export from the gulf. The study provides a foundation for improving microplastic transport simulations in coastal environments.
Mapping microplastic pathways and accumulation zones in the Gulf of Finland, Baltic Sea – insights from modeling
A hydrodynamic-particle tracking model of the Gulf of Finland found that rivers contribute 76% of microplastic inputs while wastewater treatment plants account for 24%, with most plastics accumulating within the gulf rather than drifting to the broader Baltic Sea.
Model uncertainties of a storm and their influence on microplastics / sediment transport in the Baltic Sea
Researchers used ocean circulation modeling to simulate how microplastics and sediment are transported in the Baltic Sea during storm events, identifying uncertainty in the models as a key challenge. Despite this, the approach helps predict where microplastics accumulate on the seafloor, which is otherwise expensive to measure directly.
Transport and Behavior of Microplastics Emissions From Urban Sources in the Baltic Sea
Researchers compiled microplastic emission data for urban sources in the Baltic Sea region and modelled transport and deposition of polyethylene, polypropylene, and PET particles using 3D simulations. The study found that combined sewer overflow systems and untreated wastewater are major pathways for microplastics, with particle density strongly influencing transport trajectories and depositional patterns.
Modeling transport of microplastics in enclosed coastal waters: A case study in the Fethiye Inner Bay
A numerical model was used to simulate how microplastic particles move through the Fethiye Inner Bay in Turkey, identifying coastal areas where plastics are likely to accumulate. Such transport models are essential for predicting where marine protected areas and cleanup efforts will be most effective.
Modeling the Accumulation and Transport of Microplastics by Sea Ice
Researchers used numerical modeling to examine how positively and neutrally buoyant microplastics accumulate in and are transported by Arctic and Southern Ocean sea ice, finding that sea ice acts as a significant seasonal reservoir and redistribution mechanism for microplastic pollution in polar regions.
Emission, Transport, and Deposition of visible Plastics in an Estuary and the Baltic Sea—a Monitoring and Modeling Approach
Researchers combined field monitoring and computer modeling to track how large micro- and mesoplastics (1–25 mm) travel from a German city through a river estuary and into the Baltic Sea, finding that estuaries and nearby beaches are major accumulation hotspots. The study shows that visible plastic particles are useful for modeling large-scale transport patterns, but cannot serve as reliable indicators for the far more abundant smaller microplastics below 1 mm.
Physical transport properties of marine microplastic pollution
Researchers reviewed the physical transport properties of marine microplastics — including buoyancy, settling velocity, and biofouling effects — and developed models predicting the dispersal of both pelagic and benthic plastic pollution from land-based sources across different ocean regions. The study highlights how hydrodynamic behavior varies by polymer type and particle size, leading to differential accumulation patterns in surface waters, the water column, and seafloor sediments.

Modeling the influence of biogeochemical processes on the transport of microplastics in the Arctic Ocean
Researchers modeled how seasonal marine biological processes — including biofouling by algae and zooplankton ingestion and excretion of microplastics — affect vertical transport of microplastics in the Arctic Ocean. The model showed that biological processes significantly alter where microplastics accumulate in the water column across seasons. These findings improve predictions of how microplastics distribute in polar oceans, where they can be sequestered or released back to the surface.
