Field data constrain ocean mercury budget

Thanks to recent measurements during several oceanographic expeditions, among them GEOTRACES cruises, estimates of the total amount and spatial distribution of anthropogenic mercury in the global ocean were substantially improved. Global budgets of total mercury suggest that there has been a tripling of the surface water mercury content and a ~150% increase in the amount […]

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 al., 2011). Both were acquired along two IPY-GEOTRACES sections: SR3 CASO-GEOTRACES (GIPY6) and ZERO&DRAKE (GIPY5) respectively. Hg species distribution suggests distinct features in the Southern […]
