Short summary
Particle tracking models allow us to explore pathways of floating marine litter, source to sink, between countries. This study shows the influence of seasonality for dispersal in the Bay of Bengal and how ocean current forcing impacts model performance. Most litter beached on the country of origin, but there was a greater spread shown between countries during the post-monsoon period (Oct–Jan). Results will inform future model developments as well as management of marine litter in the region.
