  abstract = {{P}acific {O}cean tuna is among the most-consumed seafood products but contains relatively high levels of the neurotoxin methylmercury. {L}imited observations suggest tuna mercury levels vary in space and time, yet the drivers are not well understood. {H}ere, we map mercury concentrations in skipjack tuna across the {P}acific {O}cean and build generalized additive models to quantify the anthropogenic, ecological, and biogeochemical drivers. {S}kipjack mercury levels display a fivefold spatial gradient, with maximum concentrations in the northwest near {A}sia, intermediate values in the east, and the lowest levels in the west, southwest, and central {P}acific. {L}arge spatial differences can be explained by the depth of the seawater methylmercury peak near low-oxygen zones, leading to enhanced tuna mercury concentrations in regions where oxygen depletion is shallow. {D}espite this natural biogeochemical control, the mercury hotspot in tuna caught near {A}sia is explained by elevated atmospheric mercury concentrations and/or mercury river inputs to the coastal shelf. {W}hile we cannot ignore the legacy mercury contribution from other regions to the {P}acific {O}cean (e.g., {N}orth {A}merica and {E}urope), our results suggest that recent anthropogenic mercury release, which is currently largest in {A}sia, contributes directly to present-day human mercury exposure.},
