In a new study published in the journal Chaos, scientists Larry Pratt and Irina Rypina from the Woods Hole Oceanographic Institution in Massachusetts turned to 3D modeling to understand how microplastics move in chaotic environments like the ocean. Because oceans are so vast, gathering sampling data isn’t an option. So the researchers delved deep into modeling how tiny particles move in a 3D fluid, and found that microplastics tend to eventually form an “idealized eddy” (circular current) that closely resembles a kind of closed-loop tornado of ecological destruction.
