Plastics and other man-made debris enter the ocean by a variety of pathways, including beaches, rivers and waterways, but also as a result of natural disasters as storms, tsunamis, floods, losses during fishing activities, and accidental or illegal dumping from ships. Whatever its source, debris in the ocean is transported by ocean currents, waves, and wind. The movement of litter of various size and buoyancy is difficult to predict because of poorly known near-surface currents and complex hydrodynamics of interaction of solid objects with these currents, waves, and wind. Furthermore, solid materials behave differently from oil spills or other liquid chemical contaminants. Litter in the ocean, from microplastics to large visible objects, is a major environmental concern because of the potential effects of these, often human-made, materials on individual marine organisms and the whole ecosystem. The purpose of this SCOR working group is to identify gaps in our knowledge of the processes that control the distribution and movement of ocean debris and suggest steps to improve the modeling and observation of these processes, including remote sensing with satellites.
