Some recent GEOTRACES science findings are reported below.
Local particulate maxima in many bioactive trace metals (cadmium, Cd; cobalt, Co; nickel, Ni; vanadium, V; and zinc, Zn) are found in the upper Oxygen Deficient Zone (ODZ), coincident with […]
Bridgestock and his co-workers reveal for the first time that natural lead can be detected again in the surface water of the North Atlantic.
First paper of the SCOR working group on modelling chemical speciation in seawater (WG145) The form in which a trace element or other component of seawater is present, and its […]
By coupling neodymium (Nd) and radium (Ra) isotopes and Rare Earth Element (REE) signals, Henning Fröllje and co-workers (2016, see reference below) show that the coastal Hawaiian waters are affected […]
Insoluble thorium (Th) isotopes are particle reactive while their radioactive parents are fairly soluble. This difference of behaviour has allowed chemical oceanographers to use Th isotopes to develop understanding about […]
High-quality dataset of dissolved zinc (Zn) from the US GEOTRACES EPZT cruise (GP16 section) allows Roshan and co-workers (2016, see reference below) to revisit the oceanic budget of dissolved Zn. […]
Since the phasing-out of leaded automobile gasoline, the imprint of industrial lead is decreasing everywhere.
The first modern data set of dissolved scandium (Sc) in the open ocean is presented. Thanks to three GEOTRACES cruises, its distribution is compared between the different oceanic basins. This […]
Gadolinium (Gd) is increasingly used in contrast agents for magnetic resonance imaging. It is therefore released in the wastes of hospitals and research centres. As a consequence, Hatje and collaborators […]
