ClearEstimation of bottom microplastic flux in the Indonesian seas
Using ocean circulation models and Lagrangian particle tracking, researchers estimated microplastic flux to the seafloor from 68 Indonesian rivers, finding that accumulation concentrates within 50-100 km of major islands. The Karimata Strait, Java Sea, and South Java were identified as the primary accumulation zones within Indonesia's Fisheries Management Areas.

Hydrodynamic modeling was used to track microplastic transport in the Java Sea off North Indramayu, Indonesia, predicting accumulation zones influenced by tidal currents and seasonal winds. The study provides a modeling framework for understanding microplastic distribution in Indonesian coastal waters, which receive high plastic inputs from land.

Researchers used global Lagrangian particle tracking simulations incorporating ocean currents, waves, and variable windage to identify sources of marine debris accumulating at Seychelles and other remote western Indian Ocean islands, finding that high-buoyancy terrestrial debris originates primarily from Indonesia and South Asia, while fishing gear fragments and shipping waste also contribute significantly with seasonal accumulation peaking during February to April.

Researchers used numerical modelling combined with artificial debris pathway analysis to investigate how marine debris from the Citarum River disperses around Muara Gembong in Jakarta Bay, finding that debris trajectory patterns differ substantially between the northwest and southeast monsoon seasons due to varying ocean currents, tides, and wind patterns.

Researchers applied a probabilistic model to global satellite-tracked ocean drifter trajectories to map marine debris pathways, identifying five subtropical convergence zones maintained by Ekman currents where floating debris — including microplastics — preferentially accumulates, confirming predictions with direct ocean surface measurements.
A particle tracking model approach to determine the dispersal of riverine plastic debris released into the Indian Ocean
Researchers developed a particle tracking model to simulate the dispersal of riverine plastic debris released into the Indian Ocean from surrounding landmasses. The study found that plastic accumulation on beaches peaked during monsoon seasons, with ocean currents, wind, and wave action driving distinct transport patterns, providing valuable data for identifying high-risk coastal areas and informing cleanup strategies.

Researchers used a Lagrangian particle-tracking model to simulate microplastic transport in the Ionian Archipelago, finding that oceanographic currents drove significant dispersal of particles released from coastal population centers, with implications for biodiversity in this ecologically sensitive part of the Mediterranean.
Beaching patterns of plastic debris along the Indian Ocean rim
Researchers used Lagrangian particle-tracking simulations to model the beaching patterns of plastic debris along the Indian Ocean rim, finding that the absence of a subtropical gyre in the Northern Hemisphere Indian Ocean means plastics likely accumulate on coastlines rather than forming a garbage patch. Results showed a large amount of plastic ends up on coastlines in the Northern Indian Ocean while some crosses the equator into the Southern Hemisphere.
Simulation of microplastic transport and dispersion based on a three-dimensional hydrodynamic particle-tracking model in the Beibu Gulf
Researchers developed a three-dimensional hydrodynamic particle-tracking model of microplastic transport in the semi-enclosed Beibu Gulf, finding that monsoon-driven circulation controls dispersal patterns, with microplastics dispersing up to 205 km in spring and storm surges such as Typhoon Yagi significantly intensifying transport and expanding nearshore high-concentration zones.

Researchers used ocean circulation modeling to investigate the role of Indian Ocean dynamics in accumulating buoyant marine plastic debris, examining how Ekman convergence and regional current patterns shape the distribution of floating debris in the Indian Ocean subtropical gyre.
Marine Plastic Drift from the Mekong River to Southeast Asia
Using the OpenDrift ocean model with seasonal monsoon dynamics, this study simulated how plastic debris from the Mekong River spreads across Southeast Asia. Results show that most plastics end up stranding on the coastlines of the Philippines and Indonesia, with seasonal monsoon patterns strongly influencing dispersion pathways. The findings help prioritise where plastic management and clean-up efforts are most urgently needed in one of the world's most plastic-polluted regions.

Researchers found microplastics in sediments along Kaliratu Beach in Indonesia at concentrations of 25–57.5 particles/kg, with fibres, fragments, films, and pellets all present, and used hydrodynamic modelling to trace how seasonal monsoon currents distribute them along the coastline. The findings highlight that even relatively remote Indonesian coastal areas near shrimp ponds and other anthropogenic activity are accumulating measurable plastic pollution.
