  abstract = {{T}he ocean's role in climate manifests itself through its high heat capacity, its own rich internal dynamics and its ability to transport vast quantities of heat and freshwater. {O}f particular interest is the global ocean circulation associated with the {A}tlantic meridional overturning ({AMOC}). {B}ecause observations are sparse, the detailed global structure of the {AMOC} remains poorly understood, particularly the pathways along which water returns to the {A}tlantic to compensate the export of {N}orth {A}tlantic {D}eep {W}ater ({NADW}). {H}ere we provide the first quantitative 3-dimensional global view of the {AMOC} using a {L}agrangian reconstruction which integrates hundred of thousands water particle trajectories in an ocean model. {T}he resulting pattern elucidates the role of the wind in structuring the pathways of the {AMOC}. {I}n particular, the {L}agrangian analysis reveals a strong link with the three subtropical gyres of the southern hemisphere ({SH}), which merge into a "supergyre' spanning the three ocean basins. {T}he coupling between the upper ocean wind-driven circulation and the overturning in the model suggests that changes in the {SH} winds can alter the pathways of the {AMOC}, and therefore the water properties and the associated heat and freshwater transports.},
