Some recent GEOTRACES science findings are reported below.
De and colleagues provide a high-resolution record of magmatic input and associated hydrothermal activity over the past 49 kyr from a core recovered from a magmatic segment of the slow-spreading Carlsberg Ridge in the Indian Ocean.
Since neodymium isotopes are used as proxies for past ocean circulation and, more rarely, past weathering, constraining the modern Nd cycle is a major challenge for marine geochemists…
By analysing peat cores, Chuxian Li and her colleagues have shown how populations of nesting seabirds have fluctuated on a sub-Antarctic Island over the last 8,000 years.
Thanks to the thorough development proposed by Alifia and co-workers, the community may have a solution to the shortage of Nobias Chelate PA-1…
Tian and co-authors investigate dissolved iron concentrations and isotope compositions in the western Weddell Sea…
In the ocean, up to 99% of the dissolved iron is strongly complexed with organic compounds known as iron-binding ligands…
The equatorial Pacific Ocean is a region of contrasts: in the west, rivers and sediments supply large amounts of iron, while in the east, iron deficiency limits the growth of phytoplankton…
Measurements of beryllium-7 activity in surface waters provide a promising approach for quantifying the deposition of aerosol-bound elements at the ocean surface…
Dickson and his colleagues investigated the fate of cadmium in the Black Sea using its concentration and isotopic composition…
