  abstract = {{T}he oxygen minimum zone ({OMZ}) in the {G}ulf of {C}alifornia entrance ({GCE}) is a crucial feature of the northeastern tropical {P}acific, significantly influencing regional biogeochemical cycles and marine ecosystems. {T}his study investigates the seasonal and interannual variability of the {OMZ} upper boundaries using a high-resolution physical-biogeochemical coupled model. {T}he model results are evaluated against satellite observations, {A}rgo profiles, and in situ data, demonstrating its capability to capture key dynamical processes, including mesoscale eddies, poleward undercurrents, and coastal-trapped waves ({CTW}s). {T}he high-resolution {CROCO}-{PISCES} model reveals two alternating periods of shoaling and deepening of the {OMZ} upper boundary in the {G}ulf of {C}alifornia {E}ntrance, modulated by seasonal mesoscale dynamics and coastal-trapped wave ({CTW}) propagation. {T}his study provides novel insights into the interannual influence of {E}l {N}ino {S}outhern {O}scillation ({ENSO}) events on {OMZ} dynamics, with {E}l {N}ino driving significant deepening and contraction of the {OMZ}, and {L}a {N}ina promoting shoaling and expansion. {T}hese variations are linked to changes in mesoscale dynamics, particularly the modulation of anticyclonic circulation at the {G}ulf's entrance by equatorially forced {CTW}s associated with {ENSO}. {T}he study highlights the complex interplay between local and remote oceanographic processes in determining the {OMZ} variability in the {GCE}. {T}his research provides insights into the mechanisms driving {OMZ} dynamics in the {G}ulf of {C}alifornia and underscores the need for integrated observational and modeling approaches to predict the response of {OMZ}s to ongoing climate variability.},
