  abstract = {{W}e study the dispersion and convergence of marine floating material by surface currents from a model reanalysis that represents explicitly mesoscale eddy variability. {L}agrangian experiments about the long-term evolution (29 years) of an initially homogeneous concentration of particles are performed at global scale with horizontal current at one fourth degree resolution and refreshed daily over the 1985-2013 period. {R}esults not only confirm and document the five known sites of surface convergence at the scale of individual oceanic basins but also reveal a convergent pathway connecting the {S}outh {I}ndian subtropical region with the convergence zone of the {S}outh {P}acific through the {G}reat {A}ustralian {B}ight, the {T}asman {S}ea, and the southwest {P}acific {O}cean. {T}his "superconvergent" pathway at the ocean surface is robust and permanent over a distance longer than 8,000 km. {T}he current variability is crucial to sustain this pathway. {P}lain {L}anguage {S}ummary {U}nderstanding the fate of marine and plastic debris at the ocean surface is an objective to be achieved before informing and discussing with policy and decision environmental makers. {T}he transport pathways of such material need to be precisely determined to estimate the pollution at a global scale. {B}y considering nonstationary ocean dispersion by mesoscale eddy variability, this study reveals a novel convergent zone, over a distance larger than 8,000 km, that connects the subtropical {S}outh {I}ndian {O}cean with the core of the convergent zone of the {S}outh {P}acific {O}cean. {T}he existence of a "superconvergent" pathway in addition to the five convergent zones is of interest to scientists studying plastic debris and more broadly to modelers and experimentalists studying ocean physics and biogeochemistry.},
