  abstract = {{S}ubducting slabs carry water into the mantle and are a major gateway in the global geochemical water cycle. {F}luid transport and release can be constrained with seismological data. {H}ere we use joint active-source/local-earthquake seismic tomography to derive unprecedented constraints on multi-stage fluid release from subducting slow-spread oceanic lithosphere. {W}e image the low {P}-wave velocity crustal layer on the slab top and show that it disappears beneath 60-100 km depth, marking the depth of dehydration metamorphism and eclogitization. {C}lustering of seismicity at 120-160 km depth suggests that the slab's mantle dehydrates beneath the volcanic arc, and may be the main source of fluids triggering arc magma generation. {L}ateral variations in seismic properties on the slab surface suggest that serpentinized peridotite exhumed in tectonized slow-spread crust near fracture zones may increase water transport to sub-arc depths. {T}his results in heterogeneous water release and directly impacts earthquakes generation and mantle wedge dynamics.},
