Decreasing of the industrial lead contamination in the Amundsen Sea area
Since the phasing-out of leaded automobile gasoline, the imprint of industrial lead is decreasing everywhere.

Some recent GEOTRACES science findings are reported below.
Scandium: a new oceanic tracer with surprising properties
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 […]
Gadolimium, a Rare Earth Element becoming a human contaminant and tracer of wastewater discharge in the ocean
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 […]
Onboard analysis of dissolved zinc everywhere in the open ocean with a Lab on Valve (LOV) system of the size of a bottle of wine is becoming possible
Thanks to the work of Maxime Grand and collaborators (2016, see reference below), it is now possible to analyse dissolved zinc (DZn) on board, from any kind of seawater using […]
Are the dissolved iron distributions well represented by the global ocean biogeochemistry models?
Alessandro Tagliabue and co-workers (2016, see reference below) have conducted the first intercomparison of 13 global ocean iron models against the latest datasets emerging from GEOTRACES. A large disparity in […]
An example of a fruitful international intercomparison
The reliability of the GEOTRACES data products including the eGEOTRACES Electronic Atlas is strongly related to the quality of the data acquired by the different laboratories contributing to this international effort. A […]
All mercury species measured along the GEOTRACES-UK section, South Atlantic Ocean
Total mercury (THg), methylated mercury (MeHg), and dissolved gaseous mercury (DGM) concentrations were determined along 40°S in the Atlantic Ocean. All Hg species had higher concentrations in western than in […]
Amazingly detailed compilation of the silicon cycle, with an emphasis on the oceanic silicon isotope budget
Although this article is not resulting from GEOTRACES activity, its content is definitely GEOTRACES relevant. The authors constructed an up-to-date compilation of the continental silicon (Si) cycle, including the fate […]
Water masses traced by neodymium isotopic compositions at an unprecedented level in the North Atlantic Ocean
As part of the Dutch GEOTRACES GA02 section, Myriam Lambelet analysed neodymium (Nd) isotopic compositions and concentrations at 12 profiles in the North West Atlantic Ocean, extending from the south […]
