  abstract = {{M}icroplastics ({MP}s) are ubiquitous contaminants in the ocean. {Z}ooplankton is thus widely exposed to {MP} ingestion. {H}ere, we use a global coupled physical-biogeochemical model enriched with a 3{D} representation of {MP}s to assess the global zooplankton exposure to {MP}s. {A}s expected, our results indicate that water {MP} concentration is the highest in the surface layers of subtropical gyres and coastal areas close to major {MP} sources, which is mostly due to floating {MP}s, while neutral {MP}s contaminate the mesopelagic zone. {A}dditionally, we showed that floating {MP}s may be also transported to the mesopelagic waters during the seasonal deepening of the mixed layer depth. {W}e then estimate zooplankton exposure to {MP}s based on water {MP} concentrations, plankton biomass, and zooplankton grazing rate. {T}wo main drivers lead to high zooplankton exposure to {MP}s: 1) high water {MP} contamination and 2) intense grazing activity. {S}easonally, re-stratification of surface waters may lead to {MP} vertical concentration coinciding with planktonic blooms, thus increasing contamination risk.},
