  abstract = {{T}he evolution of the seawater oxygen isotopic composition (delta {O}-18) through geological time remains controversial. {Y}et, the past delta {O}-18(seawater) is key to assess past seawater temperatures, providing insights into past climate change and life evolution. {H}ere we provide a new and unprecedentedly precise delta {O}-18 value of -1.33 +/- 0.98% for the {N}eoproterozoic bottom seawater supporting a constant oxygen isotope composition through time. {W}e demonstrate that the {A}it {A}hmane ultramafic unit of the ca. 760 {M}a {B}ou {A}zzer ophiolite ({M}orocco) host a fossil black smoker-type hydrothermal system. {I}n this system we analyzed an untapped archive for the ocean oxygen isotopic composition consisting in pure magnetite veins directly precipitated from a {N}eoproterozoic seawater-derived fluid. {O}ur results suggest that, while delta {O}-18(seawater) and submarine hydrothermal processes were likely similar to present day, {N}eoproterozoic oceans were 15-30 degrees {C} warmer on the eve of the {S}turtian glaciation and the major life diversification that followed.},
