Short summary
We tracked 33 floating devices released off the Korean coast to understand how debris moves across the East/Japan Sea. Their paths showed a route toward Japan and an early split caused by ocean circulation. By comparing observations with computer simulations, we found that the best predictions combine geostrophic currents, Stoke drift, and windage, while deeper devices also require Ekman currents. Winter favored faster eastward transport and beaching, whereas summer caused wider spreading.
