  abstract = {{W}e present a quantitative analysis of deoxygenation drivers applied to an {E}arth {S}ystem {M}odel and easily transposable to large model ensembles. {T}he preindustrial ocean breathes in oxygen in polar regions and in subtropical gyres, and breathes out oxygen in the equatorial band and in subpolar gyres. {U}nder a high-{CO}2 emission scenario for the 21st century, small deviations of these large natural oxygen fluxes cause global deoxygenation. {W}e attribute half of this trend to a decrease in oxygen solubility. {T}he other half is explained by negative trends in subduction and respiration, which largely cancel out each other. {M}oreover, 75% of the subduction decrease occurs through changes in mixing across the mixed-layer base. {O}ur analysis also highlights strong modulations of subduction at the regional scale linked to shifts in wind patterns and associated {E}kman pumping.},
