Under the Vici project 鈥淭racing Marine Macroplastics by Unravelling the Ocean鈥檚 Multiscale Dispersion Patterns鈥, my research explores the complex transport and dispersion patterns of marine macroplastics in the North Sea. Using the framework for Lagrangian modeling, I aim to trace plastic trajectories and analyse the impact of various physical forces, such as wind and waves, on their movement and accumulation.
