The world's ocean currents have the potential to transport material like plastic over vast scales, connecting leakage on one continent to impacts on another. Yet, it had recently become clear that most plastics found at any particular location are relatively local, often originating from within the same country. Effective policies to reduce the impact of plastic pollution require knowledge of whose plastic ends up where.

In this seminar, I will present some recent work on using a Bayesian framework to analyze the sources of plastics found on beaches around the world. The input to this analysis comes from Lagrangian ocean analysis simulations with the tool, which I will also showcase. I will particularly highlight results from the Indian Ocean, the Galapagos, the South Atlantic and the North Sea.
