This section presents the GEOTRACES scientific activities.
The meridional positions of the oceanic fronts separating subtropical and Antarctic waters are key to constraining the mechanisms that drive the degassing of deeply-stored CO2 at the end of the glacial periods…
Using iron isotopes and elemental records, Chu and co-workers analysed an iron-manganese crust recovered from the Hongyan Seamount, and reconstructed the sources of dissolved Fe to the Northwest Pacific Ocean…
Shukla and colleagues propose a high-resolution authigenic ƐNd record measured from a sediment core located in the eastern Arabian Sea…
This study demonstrates that Arctic outflows through the Canadian Arctic Archipelago play a much more significant role than previously recognised.
Benaltabet and co-workers analysed suspended particles collected on GEOTRACES GP21 cruise tracked from Chile to New Caledonia.
In oxygenated seawater iron binds to hydroxide ions, which results in authigenic Fe precipitation as amorphous ferric oxy-hydroxide…
Zhang and colleagues used genes coding for membrane transporters as proxies to map the distribution of the uptake and efflux of the trace metals…
Blaser and co-authors propose a new distribution of deep-water masses in the Atlantic Ocean during the Last Glacial Maximum and the Heinrich Stadial 1…
The neodymium isotopic signature of the sediment authigenic fraction is, a priori, a valuable proxy for reconstructing deep-water mass trajectories…
