Some recent GEOTRACES science findings are reported below.
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…
Silicon isotopes reveal significant lithogenic input to dissolved silicon on the Kerguelen Plateau
Establishing sources, transformations and sinks of dissolved silicon, a major nutrient in the Southern Ocean, is of primary importance…
Conservative behavior of radiogenic neodymium isotopes in the South Pacific interior
Zhang and co-workers present full-depth measurements of εNd and Nd concentrations along the GP21 transect across the South Pacific basin…
