Description:
Fossil black smoker yields oxygen isotopic composition of Neoproterozoic seawater Fossil black smoker yields oxygen isotopic composition of Neoproterozoic seawater, Published online: 13 April 2018; doi:10.1038/s41467-018-03890-w Uncertainty regarding the evolution of the oxygen isotopic composition of seawater casts doubt on past temperature reconstructions. Here, the authors present a new, precise δ18O value for the Neoproterozoic, and propose that ocean temperatures on the eve of the Sturtian glaciation were 15–30 °C warmer than present.
