Several hundred thousand tonnes of plastic waste enter the Indian Ocean (IO) every year, with an unknown fate. This thesis examines mechanisms that transport and accumulate floating plastics in the IO. In the northern IO, plastics likely end up stranded on coastlines as they move back and forth between the eastern and western side of the basin depending on the monsoon season. In the southern IO, plastics accumulate in a subtropical garbage patch that is very sensitive to wind and wave dynamics. The "drift factor" incorporates these dynamics and can improve numerical model simulations of plastic transport.
