Abstract

Marine plastic debris floating on the ocean surface is a major environmental problem. However, itsdistribution in the ocean is poorly mapped, and most of the plastic waste estimated to have entered theocean from land is unaccounted for. Better understanding of how plastic debris is transported fromcoastal and marine sources is crucial to quantify and close the global inventory of marine plastics,which in turn represents critical information for mitigation or policy strategies. At the same time,plastic is a unique tracer that provides an opportunity to learn more about the physics and dynamics ofour ocean across multiple scales, from the Ekman convergence in basin-scale gyres to individual wavesin the surfzone. In this review, we comprehensively discuss what is known about the differentprocesses that govern the transport of floating marine plastic debris in both the open ocean and thecoastal zones, based on the published literature and referring to insights from neighbouring fields suchas oil spill dispersion, marine safety recovery, plankton connectivity, and others. We discuss howmeasurements of marine plastics (both in situ and in the laboratory), remote sensing, and numericalsimulations can elucidate these processes and their interactions across spatio-temporal scales.
