Particle tracking simulation of marine debris using Lagrangian discrete and mesh spatial discretization in Banda Aceh waters
AI summary Read the abstract
Researchers used Lagrangian particle tracking simulations with oceanographic data to model the movement and dispersal of marine debris in the coastal waters of Banda Aceh, Indonesia. Such models help predict where plastic debris accumulates in coastal environments.
Ocean dynamics has a direct impact on the distribution of objects or dissolved particles such as marine debris. Hydrodynamic studies are currently an important tool to identify the potential pollution in the region. Data were collected from March to September 2019 in the northern waters of Banda Aceh. Wind data were obtained using AWS and bathymetry data were collected using the single beam echosounder. The results showed that the wind direction on the coast of Banda Aceh City was dominant towards the Northwest and Northeast with a maximum speed of 9 m/s. Wind direction will highly influence the sea surface currents dynamics that lead to longshore currents and radiation currents occur in coastal areas.Keywords:Marine debrisWasteFishery

A particle tracking model approach to determine the dispersal of riverine plastic debris released into the Indian Ocean
AI summary Read the abstract
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.
Medium-Term Oceanic Transport of River-Derived Microplastics in the South China Sea Analyzed with a Particle Tracking Model
AI summary Read the abstract
Researchers used 3D Lagrangian particle tracking simulations to model how microplastics discharged from four major rivers spread through the South China Sea over months. The study showed that particles can travel far from their sources and that the ocean floor receives substantial long-term deposition of river-derived microplastics.
Numerical Simulation of River-Borne Debris Trajectories and Dispersion Patterns in Lamong Bay, Indonesia
AI summary Read the abstract
Scientists used computer modeling to track how plastic waste moves through Lamong Bay in Indonesia, finding that ocean currents and seasonal wind patterns push floating plastic debris toward river mouths and different parts of the bay depending on the time of year. This matters because that plastic breaks down into microplastics that can enter the food chain through fish and shellfish harvested from these waters, and this kind of pollution-tracking research helps identify where cleanup efforts would have the biggest impact.
