Decoupling of Barium and Silicon at the Congo River‐Dominated Southeast Atlantic Margin: Insights From Combined Barium and Silicon Isotopes
The correlation between concentrations of dissolved barium (dBa) and silicon (dSi) in the
modern ocean supports the use of Ba as a paleoceanographic proxy. However, the …
