ClearA coupled Lagrangian-Eulerian model for microplastics as vectors of contaminants applied to the Mediterranean Sea
A coupled Lagrangian-Eulerian ocean model was developed to simulate microplastics as vectors for adsorbed chemical contaminants in the Mediterranean Sea, tracking plastic particle trajectories alongside pollutant exchange dynamics. The model demonstrates that microplastics can transport contaminants across basin-scale distances and deliver them to organisms far from the original pollution source.
Lagrangian tracking of river microplastics in the Mediterranean Basin
Researchers applied a Mediterranean river microplastic source scenario to Lagrangian dispersion simulations using high-resolution 3D current fields from the SYMPHONIE hydrodynamic model, tracking river MP inputs through the semi-enclosed Mediterranean Basin to quantify sources, transfers, and accumulation hotspots.
Lagrangian Transport of Marine Litter in the Mediterranean Sea
Researchers analyzed the largest available set of Lagrangian drift data from the Mediterranean Sea to model floating litter transport, finding a general tendency for plastic debris to accumulate in the southern and southeastern Levantine basin — areas not yet targeted by observational campaigns.
Influence of Particle Size and Fragmentation on Large-Scale Microplastic Transport in the Mediterranean Sea
Modeling of microplastic transport in the Mediterranean Sea showed that particle size and density strongly influence vertical distribution and large-scale dispersal patterns. Incorporating plastic fragmentation into the model predicted mass loss over time but also a shift toward smaller, more numerous particles that travel further and are harder to remove.
A Regional Lagrangian Model for Assessing the Dispersion of Floating Macroplastics from Different Source Types over the Iberian Peninsula in the North Atlantic Ocean

Modeling the Pathways and Accumulation Patterns of Micro- and Macro-Plastics in the Mediterranean
A basin-scale hydrodynamic model tracked plastic debris pathways in the Mediterranean Sea, showing that coastal currents concentrate plastics in the northwestern basin and that both riverine inputs and sea-based sources contribute substantially to the distribution hotspots observed at the surface.
The dynamics of microplastics and associated contaminants: Data-driven Lagrangian and Eulerian modelling approaches in the Mediterranean Sea
Researchers compared Lagrangian and Eulerian data-driven modelling approaches to simulate microplastic dispersal and associated organic pollutant transport in the Mediterranean Sea, finding that adsorption-desorption dynamics between microplastics and hydrophobic contaminants must be coupled for accurate pollution assessment.

Pathways and Hot Spots of Floating and Submerged Microplastics in Atlantic Iberian Marine Waters: A Modelling Approach
Researchers combined a global ocean reanalysis model with a Lagrangian particle-tracking model to simulate the transport pathways and accumulation zones of both floating and submerged microplastics originating from southwestern Iberian coastal waters. The modelling approach identified key hotspots and transport corridors for microplastic pollution in Atlantic Iberian marine waters.

Researchers used the Campania Regional Ocean Model coupled with a Lagrangian particle tracking algorithm to simulate three-dimensional transport of microplastics of varying size and density in the Gulf of Naples during winter and summer 2016. The simulations reveal how seasonal hydrological differences and polymer properties drive distinct horizontal and vertical dispersion patterns for microplastics in this heavily anthropogenically stressed coastal sea.

Researchers combined Lagrangian particle-tracking modelling with in-situ manta-net trawls north of the Balearic Islands and along the Balearic Front in autumn 2019 to infer the origins of Mediterranean microplastics. They found that the area north of Mallorca acts as a temporary three-month retention zone for microplastics originating from the Northern Current and Gulf of Lion, while retention along the Balearic Front was less clear due to frontal dynamics and strong northerly winds.

The findings reveal how riverine microplastics from Europe can reach remote Arctic regions through ocean current pathways.
