Lead isotopes tracks leakage of Indian Ocean seawater into the Atlantic Ocean
Stable lead isotopes have been measured by Maxence Paul and co-workers along 40°S during the first and second legs of the UK GEOTRACES cruise (GA10) in the Atlantic Ocean. They […]

Analyzing rapidly, precisely and semi-automatically lead isotopes on variable volumes of seawater (up to 1000 ml)
Zurbrick and co-authors present a relatively fast (2.5–6.5 hours), semi-automated system to extract lead (Pb) from seawater, with few chemicals yielding low blanks. They also demonstrate that subsequent Pb isotopic […]
