In the modern marine environment, barium isotope (δ138Ba) variations are primarily driven by barite cycling-barite incorporates 'light' Ba isotopes from soluti

Reconstruction of ocean paleoproductivity and paleochemistry is paramount to understanding global biogeochemical cycles such as the carbon, oxygen and sulfur cy

Lithium isotopes are a relatively novel tracer of present and past silicate weathering processes. Given that silicate weathering is the primary long-term method
