Seawater Chemistry and Hydrothermal Controls on the Cenozoic Osmium Cycle
Geophysical Research Letters, 2021 Osmium isotope ratios are a key tool to track changes in global weathering and carbon cycle evolution through time. Long‐term changes in seawater Os isotope records over the Cenozoic have been used to argue for changes in weathering from increased uplift,
