Data for Buoyancy-dependent sorting of microplastics in a numerical wave-flume with a sloping beach

Summary

Scientists used a computer model of ocean waves hitting a sloping beach to track how tiny plastic particles move based on how buoyant (floaty) they are. This matters because it helps explain why some microplastics wash up and get trapped on beaches while others get pulled back out to sea — knowledge that's important for figuring out where plastic pollution accumulates and how it might end up in the food chain, including seafood we eat. Note: this particular dataset is the underlying trajectory data from the simulations, not a full write-up of the findings themselves.
