Description: This work introduces a novel model inspired by raindrop formation, incorporating local oceanographic processes and fragment size, aiming to improve the understanding and prediction of plastic fragmentation in marine environments. The model incorporates the dependence on local oceanographic process, plastic aging and fragment size as criteria for fragmentation that were not previously addressed.

Description: In this study, using modelling tools, the dispersion of particles from land-based sources located on the Spanish Atlantic coast was analyzed over a seven-year period. The results show that the highest concentrations of plastic are found near the coast. The particle dispersion is consistent with the oceanic dynamics of each region studied. The seasonal behavior of plastics arriving in neighboring countries was also analyzed. The time-varying patterns are consistent with local hydrodynamics and the general circulation of the ocean.
