Short summary
The Indian Ocean receives a large proportion of plastics, but very few studies have addressed the sources, transport pathways, and sinks. There is a scarcity of observational data for the Indian Ocean. Most plastic sources are derived from rivers, although the amount derived from fishing activity (ghost nets, discarded ropes) is unknown. The unique topographic features of the Indian Ocean that create the monsoons and reversing currents have a large influence on the transport and sinks.
