However, the magnitude and thefate of this pollution are still open questions. Using data from theMalaspina 2010 circumnavigation, regional surveys, and previouslypublished reports, we show a worldwide distribution of plasticon the surface of the open ocean, mostly accumulating in theconvergence zones of each of the five subtropical gyres withcomparable density. However, the global load of plastic on theopen ocean surface was estimated to be on the order of tens ofthousands of tons, far less than expected. Our observations ofthe size distribution of floating plastic debris point at importantsize-selective sinks removing millimeter-sized fragments of floatingplastic on a large scale. This sink may involve a combination of fastnano-fragmentation of the microplastic into particles of microns orsmaller, their transference to the ocean interior by food webs andballasting processes, and processes yet to be discovered. Resolvingthe fate of the missing plastic debris is of fundamental importance todetermine the nature and significance of the impacts of plasticpollution in the ocean.
