  abstract = {{O}xygen minimum zones ({OMZ}s) are currently expanding across the global ocean due to climate change, leading to a compression of usable habitat for several marine species. {M}ercury stable isotope compositions provide a spatially and temporally integrated view of marine predator foraging habitat and its variability with environ-mental conditions. {H}ere, we analyzed mercury isotopes in blue sharks {P}rionace glauca from normoxic waters in the northeastern {A}tlantic and from the world's largest and shallowest {OMZ}, located in the northeastern {P}acific ({NEP}). {B}lue sharks from the {NEP} {OMZ} area showed higher delta {H}g-199 values compared to sharks from the north-eastern {A}tlantic, indicating a reduction in foraging depth of approximately 200 m. {O}ur study suggests for the first time that blue shark feeding depth is altered by expanding {OMZ}s and illustrates the use of mercury isotopes to assess the impacts of ocean deoxygenation on the vertical foraging habitat of pelagic predators.},
