Barium stable isotopes in the global ocean: Tracer of Ba inputs and utilization

YT Hsieh, GM Henderson - Earth and Planetary Science Letters, 2017 - Elsevier
Barium has been used as a biogeochemical tracer for alkalinity, productivity, and riverine
inputs in the ocean, but its oceanic cycle remains poorly constrained. Barium stable isotope …

Controls on the barium isotope compositions of marine sediments

L Bridgestock, YT Hsieh, D Porcelli, WB Homoky… - Earth and Planetary …, 2018 - Elsevier
The accumulation of barium (Ba) in marine sediments is considered to be a robust proxy for
