Microplastic pollution in the Arctic represents a critical environmental challenge, driven by the region's intricate hydrodynamics and rapidly evolving climatic conditions. This study integrates high-resolution TELEMAC-3D, TOMAWAC, and CaMPSim-3D models to analyze source-receptor pathways and identify accumulation zones for microplastics. The modeling framework incorporates wind, wave dynamics, and other processes influencing particle transport. Hydrodynamic validation was conducted via a combination of in-situ and remote sensing datasets. Results highlight potential accumulation areas and underscore the necessity of accounting for diverse transport mechanisms to accurately predict microplastic movement and deposition in Arctic waters.

Microplastic pollution in the Arctic represents a critical environmental challenge, driven by the region's intricate hydrodynamics and rapidly evolving climatic conditions. This study integrates high-resolution TELEMAC-3D, TOMAWAC, and CaMPSim-3D models to analyze source-receptor pathways and identify accumulation zones for microplastics. The modeling framework incorporates wind, wave dynamics, and other processes influencing particle transport. Hydrodynamic validation was conducted via a combination of in-situ and remote sensing datasets. Results highlight potential accumulation areas and underscore the necessity of accounting for diverse transport mechanisms to accurately predict microplastic movement and deposition in Arctic waters.
