a Salinity (blue curve; psu), potential temperature θ (red curve; ∘C), and potential density σ0 (green curve; kg m−3). b Oxygen concentration O2 (black curve; μmol kg−1) and the oxygen at 93% of saturation (red curve and dots). c Apparent Oxygen Utilization AOU (blue curve; μmol kg−1) and oxygen at saturation \({{{{{{{{\rm{O}}}}}}}}}_{2}^{{{{{{{{\rm{sat}}}}}}}}}\) (red curve; μmol kg−1). Plain curves represent Argo data, and dots represent the hydrographic sections. The uncertainty for the Argo data is computed as the standard deviation around the spatial average (gray shading), and for the hydrographic section it is computed as the standard deviation over the layer depth (error bars). The three periods (P1, P2, and P3) discussed throughout the manuscript are indicated with arrows on top of the figure.
