Trace metals in deep ocean waters: A review
A synthesis on the data available on the distribution of selected trace metals (i.e. Cadmium, Cobalt, Copper, Molybdenum, Nickel, Lead and Zinc) in the deep ocean from 1979 to 2009 […]
Science Highlights
Some recent GEOTRACES science findings are reported below.
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 […]
Measuring precisely with only 40 ml of sample
It is now possible to measure precisely manganese (Mn), iron (Fe), cobalt (Co), nickel (Ni), copper (Cu), zinc (Zn), cadmium (Cd), and lead (Pb) concentrations in seawater using only 40 […]
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 […]
Thanks to GEOTRACES-IPY, more and more iron data in the Arctic
Klunder, M. B., Bauch D., Laan P., de Baar H.J.W., van Heuven S., and Ober S. (2012), Dissolved iron in the Arctic shelf seas and surface waters of the central […]
Ocean margins: the missing term for oceanic element budgets?
Jeandel, Catherine, Peucker-Ehrenbrink, Bernhard, Jones, Morgan T., Pearce, Christopher R., Oelkers, Eric H., Godderis, Yves, Lacan, François, Aumont, 0livier and Arsouze, Thomas This paper underlines how poor is our understanding […]
GEOTRACES in the International Polar Year
The International Polar Year (IPY) 2007-2008 provided an excellent opportunity for a flying start of the GEOTRACES program. Major IPY GEOTRACES campaigns in the Arctic region (Figure 1) were the multiyear program […]
