A global compilation of the neodymium isotopic composition of seawater for GEOTRACES

GEOTRACES will allow the collection of numerous data that will be archived in the GEOTRACES Data Assembly Centre (GDAC), and will eventually contribute to create a world atlas of tracers […]

New strategy to evaluate trace element fluxes to the ocean from aerosols

Scientists participating in GEOTRACES have developed a new strategy to evaluate trace element fluxes to the ocean from aerosols (Hsieh et al, 2011). The new approach uses the common geochemical behaviour […]

Recent and original results in the Southern Ocean on mercury speciation and cadmium isotopes

For the first time detailed mercury (Hg) speciation was determined along an Australia-Antarctic section (Cossa, et al., 2011) and cadmium (Cd) isotopes along a South Africa-Antarctic section (Abouchami W., et […]
