Neodymium budget in the Arabian Sea is governed by a combination of water mass advection and dominant boundary exchange processes
Karri and Singh established the neodymium concentrations and isotopic compositions along a North-South section in the eastern Arabian Sea…
Cerium isotopes confirm that hydrogenetic iron-manganese crusts are precipitating from the oxygen minimum zone to abyssal depths
Li and co-authors provide new insights on the formation mechanism of ferromanganese crusts.
Continuous record of the Antarctic Circumpolar Current latitude over the last glacial-interglacial cycles
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…
23 Million Years of iron sources reconstructed in the Northwest Pacific Ocean using iron isotopes in a ferromanganese crust
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…
Variability of the past deep-water masses in the Arabian Sea over the last 41ka
Shukla and colleagues propose a high-resolution authigenic ƐNd record measured from a sediment core located in the eastern Arabian Sea…
Arctic outflows to Davis Strait and the Labrador Sea traced by radionuclide distributions
This study demonstrates that Arctic outflows through the Canadian Arctic Archipelago play a much more significant role than previously recognised.
Zinc and lead isotopes reveal human footprint on the most remote oceanic regions
Benaltabet and co-workers analysed suspended particles collected on GEOTRACES GP21 cruise tracked from Chile to New Caledonia.
Organic binding site heterogeneity controls amorphous ferric oxy-hydroxides oceanic sink
In oxygenated seawater iron binds to hydroxide ions, which results in authigenic Fe precipitation as amorphous ferric oxy-hydroxide…
