  abstract = {{T}he connection between the equatorial mean circulation and the oxygen minimum zone ({OMZ}) in the {E}astern {T}ropical {P}acific is investigated through sensitivity experiments with a high-resolution coupled physical-biogeochemical model. {A} validation against in situ observations indicates a realistic simulation of the vertical and horizontal oxygen distribution by the model. {T}wo sets of climatological open-boundary conditions for the physical variables, which differ slightly with respect to the intensity and vertical structure of the {E}quatorial {C}urrent {S}ystem, are shown to lead to contrasting characteristics of the simulated {OMZ} dynamics. {F}rom a {L}agrangian perspective, the mean differences near the coast originate to a large extent from the different transport of deoxygenated waters by the secondary {T}suchiya {J}et (secondary {S}outhern {S}ubsurface {C}ountercurrent, s{SSCC}). {T}he {O}-2 budget further indicates a large difference in the balance between tendency terms, with advection exhibiting the largest difference between both simulations, which is shown to result from both linear and nonlinear advection. {A}t regional scale, we also find that the variability of the physical contribution to the rate of {O}-2 change is one order of magnitude larger than the variability associated with the biogeochemical contribution, which originates from internal high-frequency variability. {O}verall our study illustrates the large sensitivity of the {OMZ} dynamics to the equatorial circulation.},
