Do not mourn Nobias any longer: InertSep ME-2 is coming!
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…
Long-range transport of iron off the Antarctic Peninsula
Tian and co-authors investigate dissolved iron concentrations and isotope compositions in the western Weddell Sea…
Seasonal variation of the dissolved iron ligands in the South Atlantic sector of the Southern Ocean
In the ocean, up to 99% of the dissolved iron is strongly complexed with organic compounds known as iron-binding ligands…
Tracing the origin of iron in the equatorial Pacific: an isotopic study
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…
Comprehensive inverse model constrains the application of beryllium-7 as a deposition tracer
Measurements of beryllium-7 activity in surface waters provide a promising approach for quantifying the deposition of aerosol-bound elements at the ocean surface…
When cadmium faces the Black Sea contrasting environment
Dickson and his colleagues investigated the fate of cadmium in the Black Sea using its concentration and isotopic composition…
Lead isotopes reveal that hydrothermal variability is driven by Sea‐Level change and transient magmatism
De and colleagues present the first millennial-scale reconstruction of hydrothermal variability at a mid-ocean ridge using lead isotopes from iron-manganese coatings…
Trace Element Dynamics in the Oligotrophic Northwest Pacific: Insights from the China GEOTRACES GP09 Cruise
This highlight summarises several articles arising from the GP09 cruise in the Northwest Pacific Ocean…
